Charger for a laptop from the cigarette lighter with your own hands. Car adapter for laptop


Currently, the problem of the work of the laptop in the car is quite relevant. There is no enough battery in a laptop for a long time, and traveling by car can last much longer than its work time. To ensure normal operation of the laptop from the automotive network and serve adapters.
Different adapters for laptop work in a car. It can be purchased in the retail network, and you can make it yourself. This article is for those who do not seek light paths and can do something with their own hands.
Different schemes on the Internet set. The general requirement for such an adapter is an output voltage of 18-19 volts, with a load current of about 2.5-3 amps.
I decided to assemble various diagrams of such adapters in this article, the performance of which was tested by practice. The schemes of these adapters with the correct assembly of the serviceable parts practically do not need to be established and are collected from quite affordable parts. So choose, as they say on your taste and color.

Auto adapters for laptop on timer 555.

As a PWM shaper for this converter, an integral Timer KR1006Vi1 is used, imported analog NE555, LM555. From its output, the signal enters the key performed on the field transistor 45N03, which can also be applied as BUZ11, CEB603, CEP703, NDP406, IRFZ33 and many others, the main thing that the maximum voltage is at least 40B, and the maximum current of at least 15a Well, the body is desirable TO-220.

The frequency of conversion of the timer generator is determined by the C1 condenser, and when the container indicated in the diagram is about 40 kHz. Pulse stop management, carried out after 5 output of the timer. Some types of imported timer analogs have another control scheme for this input, and this may not work correctly.
A paired Schottky diode can be applied as a VD2 diode, with a reverse voltage of at least 40V and the maximum current of at least 15a, as preferably in the Case-220. For example SLB1640, or STPS1545, etc. Diode VD1 - protection against cords, direct current of at least 6a. Instead of VT2, it is perfectly suitable CT315. Stabilodron VD3 Determines the output voltage of the converter.
One of the most responsible parts in this converter is choke. It is wound on a powder iron ring, a diameter of about 27 mm, used in computer blocks as a group stabilization throttle. The choke has 21 rounds, three folded with wires of PEV-1, with a diameter of 0.75 mm. Its inductance is about 44 μH and active resistance of about 0.1 Ohm.

As a housing for the adapter, a metal case is used from 50-watt electronic transformer. Her dimensions 67? 46? 30 mm. In this case, instead of two keys of the semi-bridge, you can conveniently post field-effect transistor and a diode to press them to the wall of the housing for heat removal. The transistor and diode housings must be isolated from the body with a gasket from fluoroplast or mica.
Pricing fee and location of parts on the board below in the picture.

The following scheme is almost similar to the first. Differs in the types of parts applied in the scheme. If the exact setting of the output voltage in this scheme is not needed, then instead of PR1, VD2, R5, you can put a chain from a stabitron and a constant resistor, similar to VD3, R5 in the diagram above.

The throttle in this scheme can be winding on a ferrite ring with an outer diameter of 20 to 40 mm. With magnetic permeability not lower than 2000, and may contain 50-60 turn turns, with a diameter of 1.0 mm. Its data is not particularly critical, it is also possible to wind it also on the segment of the ferrite rod, with a diameter of 8-12 mm. and a long 30-50 mm. You can also use the finished throttle from the computer power supply.
If the voltage under load of this converter is less than the required, then it is necessary to increase the number of turns of the throttle used.

The following scheme is also performed on an integral timer. In difficulty, it is practically no different from the above. This scheme implements defense against reduced input voltage The on-board network of the car, and if it is reduced below 9 V - the output voltage of the converter also begins to decline, preventing the saturation of the throttle and failure the power key. There is also a protection of exit from significant overvoltage: in case of feedback disorders, the output voltage of the converter is limited by the value of about 25 V.
The output voltage of this converter 19 volts, the maximum load current is about 4.7 amps.

The transformation frequency of this adapter can be in the range of 55 ... 84 kHz. The output voltage 5 is 4.1 ... 6 V, depending on the input voltage. This range is determined by the resistor resistor R1. In the case of low load, the modulating voltage may be lower than the specified values. The output of 4 chips is connected to the output 5 so that the generator can, if necessary, turn off and skip pulses. Such a need happens when the converter is working with a small load or without load, so that the further growth of the output voltage would occur, leading to the overload of the feedback circuit. Therefore, if the modulating voltage decreased to about 0.7 V, the reset signal arrives at the output 4 of the chip and suspended the operation of the generator. Since at low load, the generator operates in the "Stop Start" mode, the appearance of acoustic noise, but this does not prevent the normal functioning of the converter.

Power transistor KP727B can be replaced by KP723 C letters a-in, KP746 with letters A-B, as well as any similar imported, designed for permanent current of at least 15 A and having, if possible, the small resistance of the open channel.
A diode with a barrier of Schottky CD272A is replaced by 2D2998 with letters B, B, CD2998 with letters B-D, MBR1635, MBR1645, as well as any other Schottky diodes, designed for direct current of at least 15 A and reverse voltage of at least 25 VD2 diode and the VT2 transistor must be equipped with heat sinks of 50 cm2 each.
The VT1 transistor is on any other transistors in which the typical value of the base transmission coefficient is about 100 at a 1 mA collector current.
The throttle L1 is wound with a wire of PEV-2 with a diameter of 1.25 mm on two folded together ring magnetic systems KP27? 15? 6 from Permalloe MP140. It is suitable and a thinner wire, connected to a few lived with a total cross-section area of \u200b\u200babout 1 mm2. Winding contains 16 turns.
You can also apply the yellow-white ring magnetic circuit T106-26 with dimensions of 27x14x12 mm from a lot of winding choke in the computer power supply, in which case the winding of the wire with a diameter of 1 mm with a diameter of 1 mm is left, the remaining windings are removed. With an independent winding, it is performed in one full layer of wire with a diameter of 1 ... 1.25 mm. Other chokes are suitable with inductance of at least 18 μg, calculated on the tripled maximum load current.
On the other hand, the inductance of the choke should not be too large: with its inductance of the order of 100 μg and more feedback of the stabilizer, the stability may lose the sustainability, and at the collector of the VT1 transistor will be unlucky oscillations.

To connect this device to the car on-board network, or similar - wires connecting the plug and the input of the converter must be a cross section of at least 2.5 mm2. It should be borne in mind that the input current of such devices can reach 10 A. It should not flow through the spring inside the "cigarette lighter" fork. For this spring is duplicated with wire.

Auto-adapters for a laptop on the UC3843 chip.

The adapter described below is a single impulse enhancement converter collected by typical scheme On the UC3843 chip. It provides at the output voltage 16.5 V at a current to 4 A.

When assembling this scheme used SMD componentsDue to which the dimensions of the collected device are 45x30x15 mm.
The device is collected on a double-sided printed circuit board, size 37? 23 mm. From a fiberglass, a thickness of 1.5 mm. The top side of the board is used only as a screen and a common wire. Printing the device (mirror image) is shown below in the figure.

The L1 coil and C9 capacitor are installed on the reverse side of the board (a cutout is made under the coil in the board), all other parts are the same as shown in the picture. Types of applied components are shown in the table.

The correctly assembled device is not required. If another output voltage is required, the R9 resistor should be changed, based on the fact that the resistor R10 should turn out to be voltage, equal to 2.5 V.

Here, look at another embodiment of this adapter using SMD elements.

Picture of the printed circuit board of this device.

The location of the elements on the printed circuit board of this device.

The scheme of the second adapter is practically no different from the above. The only difference is that in this scheme you can adjust the output voltage in the range of 14-27 volts. The average load current is 2.5 amps.

The transistors, diodes, as well as the data of the throttle used are similar and replaced by those described in similar schemes above. Therefore, it will not stop in detail.
Below in photos, the embodiment of this scheme using the same SMD- \u003d components.

If there is no need to adjust the output voltage at the output of this converter, then the variable resistor R9 can be excluded, and select the R8 resistor so that the output voltage of the converter corresponds to the necessary one.

Auto adapters for a laptop on the KR1156EU5 chip (MS34063).

The described device increases the voltage of the on-board network of the car from 12 to 18 volts, while providing an output current equal to 3.2 amps, which is enough to work a laptop. The device is collected based on the popular domestic chip KR1156EU5 (foreign analogue - MS34063).

An embodiment of this converter in the photo below. The printed circuit board of this converter is placed in the cast aluminum housing and is closed with a lid.

Establishment reduces to the conversion frequency setting corresponding to the maximum efficiency. To do this, the input of the converter through the ammeter is connected to the source. direct current 12V voltage and a power of at least 100 W, which can be used a pulse power supply from the computer. To the output of the converter, a load resistor with a resistance of 5.1 Ohm with a capacity of 50W (for example, PEV-50) and in parallel to it - the voltmeter of the DC was connected. Capacitor C4 smoothly changing the frequency of the conversion, achieve the minimum value of the output current at a constant output voltage. If you do not need to get the maximum transducer efficiency, C4 capacitor can not be installed, but the C3 capacitor can be 360pf.
The version of the printed circuit board and the placement of parts on it is shown in the figures below.

Another adapter, made on a similar chip, differs from the above that the output voltage can be installed within the limits of the stereo resistor, and a slightly complicated output scheme.

This adapter is assembled on the printed circuit board, the size of 60x35 mm. PCB Drawing in "SL-6,0" format can be downloaded from the server.

Auto adapter for laptop on the TL494 chip.

The next auto adapter for the laptop operation from the on-board network of the car is assembled from parts from computer power supplies. As a PWM regulator, this adapter uses widespread in such power supplies, the TL494 chip and its analogues.

The PWM controller on the TL494 chip works here at a frequency of 40 kHz and controls the power field transistor.
The diagram provides at an output power of 50-60 W (at 20 V at the output) of the efficiency of 90%, and with a load of 100 W - the efficiency of 85%. The pulsation of the output voltage can reach 0.5 volts, and the maximum average input current 12a. If such pulsations are not suitable, they can be reduced by increasing the capacity of output electrolytic capacitors.
Large input current (with a load of 100 watts) requires careful printed circuit board. Power conductors (tracks) can be reinforced wire. The power input cable should have at least a sub-section of 1.5 mm?, And directly soldered to the printed circuit board.
As a weekend power transistors, it is desirable to use those in which the small resistance of the open channel. In particular, SUP75N06-07L, SUP75N03-08, SMP60N03-10L, IRL1004, IRL3705N. The BUZ11 transistor will work worse, as compared to the first, he has a five-time resistance to the open channel.
It should also be seriously related to the choice of the power diode and choke, which must be calculated on the current, not less than 10a.

Auto adapter for laptop on the UC1843 chip.

Another auto adapter for the work of the laptop from the onboard network of the car is assembled for not very cheap and not so common chip, PWM-regulator UC1843. The diagram provides at the output of the voltage 18 volts with a load current up to 5 amps. Consider the chart of the adapter.

The output voltage of this adapter can be installed in the range of 16-35 volts, variable resistor R2. To cool the transistor and diode at a load current up to 5 amps - a sufficiently small radiator, for example, from computer power supplies. Option of execution of this scheme, see below in the figure.

In this adapter, you can also apply transistors and diodes, which have been described in the above schemes, since all of them are mainly built according to one principle, therefore I will not stop in detail on their replacement.

Auto adapters for laptop on the LT1070 chip, LM2577T-ADJ.

I will give a couple more schemes of auto-adapters, using not so widespread and not very cheap chips.

The first auto adapter is assembled on the LT1070 chip. This is perhaps the most expensive and less affordable chip from all designs described here. This is a DC-DC converter that supports a 19 volt voltage at the output, with a load current 2.5-3A.

To control the level of output voltage and its stabilization, the internal stabilization scheme of the LT1070 chip is used. The essence of her work is that it thus changes the diet of pulses entering the primary winding of the transformer so that at the output 2 A1 was constant pressure 1.24V.
The day of obtaining a stable output of the voltage, you need from the output of the secondary rectifier on VD2, constant voltage through the divider - to submit to the output 2 A1. And the ratio of the separator resistors should be such that, with proper voltage at the output, the output 2 A1 was 1.24V voltage. Divider resistors are R3 and R4.
The exact selection of R4 set the required nominal stabilized output voltage. In this case, it is 19V.

For winding the transformer, a ferrite ring is taken by an outer diameter of 32 mm. from ferrite 2000nm. The ring must be wrapped with a thin layer of fluoroplastic film or lacker. It is possible to turn the ring with nothing, but to cover the epoxy paca layer. After its drying, you can wind up windings. It is possible that the ring of different diameter and the ferrite brand can be used to wind the transformer, - you need to experiment!
The primary winding contains 40 turns of the winding wire consisting of two together folded wires of PEV 0.43. You can use a single wire with a cross section of 0.9, but the secondary winding will be hardened it contains 70 turns of the same double wire. First, the primary winding is wound, and then onto its surface is secondary, laying the wire in the same direction as the primary wound. The diagram of the start of the transformer windings is marked with points.
For chokes, rings with a diameter of 18-20 mm are used. They contain 30 turns of the same double wire, as well as for winding the transformer.
The circuit of the converter is collected on the printed circuit board with one-sided location of the printed tracks.

The chip and diodes must be strengthened on radiators. A common radiator can serve a metal housing in which the converter is collected.
With proper installation and serviceable parts, the establishment is reduced to checking output voltage. If it differs from the required need to change the resistance of the resistor R4. Reducing the resistance leads to an increase in voltage, and an increase in its decrease.

The second, similar to the characteristics of the adapter, is assembled on the LM2577T-ADJ chip. This scheme is from all given, probably the simplest, but the chip applied here is also not as widely available, although much more often is on sale than LT1070 Yes, and not so road as the aforementioned (saw from $ 5).

The printed circuit board for this adapter was not done, the details were installed on the dump fee and the installation was made by mounting wires. On the choice of throttle and diode, I will not stop, all this is in the descriptions above, so choose to your taste.

The microcircuit is attached to the aluminum plate, which serves as a radiator, and the whole design is placed in a suitable plastic case.

I hope that of the whole diversity of the schemes described, you will find yourself the most suitable on the execution and applied in the assembly of the most affordable radio components.
Good luck in the assembly.

Many have a car, and there is almost everyone a laptop. There are situations when you need to power or charge your battery in a car, but the question arises like?

Nutrition Laptop from Auto It is impossible, eating the voltage of the on-board network is only 13.5 volts (on average). It is for solving this problem and use the voltage converter made by its own hands.
The scheme of this non-complex self-container is presented below.

The current for the current of this scheme is 8 amp, at a voltage of 19 volts. At the time when any modern laptop consumes no more than 4 amps, the stock is decent.

Let's look at the applied details and the principle that this converter works. Its heart is a UC3843 chip (a generator with pulse modulation and a comparator to stabilize the output voltage) in the type-inclusion. The muscles are choke L1 and the assembly of field transistors VT1 (IRF7341), in my case it is applied P1203, powered from motherboard Some laptop. Small dimensions of the device are achieved by the use of parts for surface mounting and high frequency of conversion (150 kHz, respectively, elements R2 C2). Pumping increased voltage It occurs on the throttle L1 and the Schottky Diode VD1 rectifier. The throttle is wound on a standard yellow-white ring from computer Block Nutrition. The number of turns of 20 - 25, with a wire of 1.5 mm (it is more convenient to wind up a three-wire conducted with a wire of 0.6). Vd 1 diode is applied from the same block as the ring. And has a marking F2020CT. The output voltage, if desired, you can get another, for this you need to select the R9 resistor.
A little about possible replacements and design features.

As I said instead of the IRF7341 matrix, the P1203 field transistor was applied, but something simpler, type IRFZ48N, IRFZ44N, IRFZ34N, CP727B, KP723, KP746, any of the KP812 series, or other powerful N-channel are applied from domestic transistors. feller.

It is constructive homemade The converter is executed on circuit board, 5 to 4 centimeters. Of course, it was possible to ship a printed fee, but there was little time therefore.

Every year the number of users with electronic gadgets increases. In the modern world, it is quite rare to find a person who does not at least one electronic device. Most often, the user has much more such gadgets. But since all these devices are powered by rechargeable batteriesThat allows the user to work on it almost anywhere, often charging enough for a while. How is this problem solved?

Solving a problem for motorists

A person buys a laptop or another gadget in order to have freedom of movement around the city, simultaneously performing one work. Quite often moved by car. Having a special device, at any time you can recharge your gadget. And although the car charge for a laptop is not part of accessories sold along with the car, nevertheless, it can be easily purchased.

Thus, using the charger, the laptop user can freely perform the necessary job anywhere in the city by connecting its gadget to the onboard network of the car.

Types of existing charger

Of course, it is easiest to buy such a device. Now there are many different instances of the charging devices, so it is not so easy to choose the desired model. What car charging for a laptop are you needed? They can be divided into two categories.

  1. The first category includes devices whose principle is based on stabilization. on-line voltage car network. The maximum voltage at the output of such an adapter does not exceed the power of the car network.
  2. The second category includes a universal automotive charging for a laptop, the output voltage of which is 220 volts. The functioning of this charging is the transducer issuing an output aC voltage The same as in the home network.

Each of these types of charging has its advantages and disadvantages.

Production of charger with your own hands

But sometimes there are cases when an ordinary charger is not enough. Since some laptops consume a lot of electricity, the voltage at the output of such a device should be at least 18-19 volts. In this case, the voltage of the on-board network is not enough for the normal functioning of the laptop. Therefore, some are asked as a question: "How to make a car charging for a laptop?". Usually the problem is solved using a voltage converter. A device is collected that the constant voltage of the on-board network converts to a variable with a 220 volt indicator. The laptop connects to the product in the same way as the electrical outlet in the apartment. The diagram of such a device is shown in the figure.

The home-made charge assembly begins with the selection of radio components presented in the diagram.

  • The main and determining the quality of the operation of the converter is the part is the high-frequency transformer. It is from him that the selection of radio components begins.
  • Then it is worth paying attention to diodes, the reverse voltage of which should not exceed 100 volts at the transition.
  • The key element of the scheme is a thyristor.
  • Then they select a transistor with a high current transmission coefficient.
  • Finally, the resistors must be purchased exactly at par and power, otherwise the converter will not start.

After all the details are purchased, you can start charging. But it is important to remember that such a car charging for a laptop will require not only a complete set of radio-mounted tools, but also a certain experience in mounting and adjusting radio engineering devices. Before using such charging, you need to check all its parameters using measuring instrumentsAnd only after that you can connect it to the laptop. As a result, the assembly may turn out a product similar to those depicted in the photo.

Industrial AC Inverters

Creativity brings tremendous satisfaction to the constructor, but nevertheless, the automotive charge for a laptop made by an industrial enterprise will be much more reliable than the device created by his own hands. In addition, we make a high-quality alternating current inverter at home very problematic. Such devices need elements made with a high degree of accuracy. Therefore, any error in the manufacture can lead to the loss of the performance of the gadget.

Finally

Among other things, automotive charging for a laptop can be made not only at different enterprises, but also in different countries. Usually, in the standard set of laptop, such an accessory, as a charger, is not supplied - the driver buys it additionally. If you pay attention to the price range of car chargers, then the cost of models may differ several times. Of course, a desire will always be present to save on such an accessory, but it is important to remember that a cheap device can output your laptop. Usually it sin small manufacturers from China, producing the cheapest charging on the computer market.

For those who are within a long time on trips, it is important to know whether it is possible to charge a laptop in the car. Yes, it is possible to perform it, you just need to know some subtleties. The procedure is carried out from the cigarette lighter, and due to this you do not need to wait until the technique charges from the outlet of the house.

How to charge a laptop in the car? This process will not be difficult for any computer owner.

Charging from the cigarette lighter

A car adapter for a laptop is considered an important thing for a business person, especially for who constantly drives. The technique is discharged at any time, and there is no socket everywhere. It means that to constantly have access to the computer, you need to use modern means.

How to charge a laptop in a car from the cigarette lighter? Connecting to the called source will be sufficient for your technology. But the voltage of the device is not 220 V, but less. Therefore, you need to use a special adapter that performs the voltage conversion and the supply of electrical current with the necessary parameters.

Working from the mains, also has such a device. Network parameters are not suitable for the current type that is required by the power supply, so the main component is considered to be the converter. The adapter has a similar principle of operation.

Features of charging

Chargers are characteristic. The rear panel of the equipment contains information about what output voltage is suitable for technology. As a rule, this indicator is equal to 15-25 volts, and the current power is 4-5 amps. This information must be taken into account when choosing an adapter.

Power supplies have different connectors, since each technique has their own types of outputs. Therefore, it is desirable to choose a device to your manufacturer's native laptop. Another characteristic is the properties of the cigarette lighter. At the output, the voltage is 10-12 volts, and the wagon - 25 V. Chargers are not suitable for each technique.

Is it harmful?

Do not everyone know that a laptop can be charged in the car. This car does not hurt, but the laptop? How does it affect the technique?

It is believed that you should not connect a portable computer to the cigarette lighter, since the power supply is completely different here, if compared with the usual power grid. This is true, but precisely because of this, an adapter is applied. And if a device suitable for all properties is selected, then you can easily carry a laptop charging when traveling. And on the road, no problems will appear with this.

Characteristics of charger

How to charge a laptop in the car, it is better to consult with a specialist. It is advisable to contact the electronics stores. There are sold car power supplies from different manufacturers suitable for specific each charging has its own parameters, and before issuing on sale they are tested.

We continue to find out how to charge a laptop in the car. To recharge, you need to use a car inverter - it in the car serves a 220 V socket for your laptop. Its, in principle, can be used for any technique. In general, the adapter connected to a portable computer through the cigarette lighter is considered the most convenient option for recharging, as it consumes little energy and safe.

Autonomous device

If it is not entirely clear how to charge the laptop in the car, you should read the principle of operation of the transport adapter. Its power holds within 150 W. Therefore, it is necessary to choose such a device that is protected from overload. Charging occurs when the ignition is turned on, that is, when the engine is running, because when connected to the cigarette lighter, the battery is quickly sisted.

It is necessary to purchase an autonomous adapter with the same volt and amps, as well as on the power supply unit. And even better, as we said, buy the device of the same brand as the computer. The process of its recharging lasts about 3 hours, while the phone can be charged in an hour.

Purchase

Often in the range of specialized stores you can find universal devices to help solve the problem of how you can charge the laptop in the car. The named set usually has from 4 adapters. When buying, you need to check if there is a suitable connector. Cost universal devices Located within 500 to 2,000 rubles.

But whatever adapter you choose, it connects in the same sequence - one end of charging is connected to the cigarette lighter, and the other (with a suitable adapter) to the laptop.

If the store does not contain a device with a suitable connector, then you should contact the dealer network of the manufacturer of their laptop. But the original charging is more expensive - about 2,000-2 500 rubles.

When choosing, pay attention to some nuances:

  • On the connection area of \u200b\u200bthe wire and the connector should be protection. If it is missing, then it is in this place that the wire will be overwhelmed.
  • Wire length. In all machines, the cigarette lighter is in different places. Therefore, it is desirable to buy a charging with a long wire that can be adjusted.

It should be borne in mind that high-quality devices have special protection against short circuit. The remaining characteristics do not matter, so appearance, design and weight The product can be any. If a suitable charger is bought, you can always infect a laptop in the car. It is very convenient, because the technique can work on the way.

The process of charging a laptop without using a charger is quite complicated, but quite performing the task. In this article, we will describe you as much as possible about the ways to implement the laptop recharging tools, if there is no native and, which is important, a serviceable power adapter.

Due to the fact that the actions for charging a laptop without a power adapter require direct interference with the work of a laptop computer, it is important to make a note regarding the automatic solution to the problem with turning on the device without using the battery and the charger. Thus, after a careful study of the prescriptions, you can not only fill the battery energy, but also to force the laptop to work at all without a built-in power source.

Among other things, you should understand some additional aspects that are subject to computer malfunctions and directly related to the reason for the need for this kind of charging. Deliching the essence of what was said before performing recommendations from the instruction, be sure to make sure that the laptop is managed.

Be extremely careful, performing any actions originally not provided by the manufacturer! In general, even after a clear execution of recommendations, we cannot provide a guarantee that the device will be charged to the level of the norm. Moreover, complications may well occur, for example, in the form of a short circuit and burnout internal nutrition components of the laptop.

Method 1: Charge the battery without a laptop

This is the method of charging a laptop to disable the battery itself from the laptop computer directly and, by using some tools, fill the reserve of energy. At the same time, you can still need a power adapter from a laptop, which, however, it is quite possible to change to any other, satisfying the requirements of the technical specification.

Please note that within the framework of our detailed instructions For this method, we also reviewed the possibility of replacing the battery to a new component. Based on the topic of this article, these notes may well be useful, since by replacing the old discharged battery on a charged new, it is possible to restore the full performance of the laptop.

Method 2: We use direct connection

By analogy with the first way, this method is to extremely radical and intended for users who, at least, have experience working with those or other electrical appliances. Despite this, of course, even a beginner can cope with the required tasks, however, if the slightest doubts arose, it is better to go right away to the next section of the article.

The laptop may come to disrepair from incorrect actions and violations of security rules.

Turning to the essence of the method of direct connection, it is important to make a reservation on the small number of existing methods. As a result, whatever the charge options you choose, you have certain requirements, in general, the equivalent to buy a new charger.

Deciding with the priorities, you will need to prepare a pair of small wiring with copper soft cores and any powerful external power supply, voltage from which, at least, should be equivalent to the standard adapter. Immediately, consider that with a lack of voltage charge to the battery, it will still be, but not completely.

The lack of a voltage of the used power supply is most likely to manifest themselves in significant liabilities of the performance of a laptop computer.

To avoid problems, you should work with a laptop turned off and the power adapter disconnected from the network. It is also desirable to remove the battery until the electricity transmission channel is adjusted to the laptop.


  • centre - «+» ;
  • edge - «-» .

The neutral line usually passes through negative contact.

  • For reliability, use the plastic tube or wind the positive pole independently.
  • Anyway, your goal is by any ways to fix the wire on the middle segment of the charging socket.
  • With a negative pole, you need to proceed in a similar way, however, in this case, the wire should contact only with a side metal framing.
  • Additionally, make sure that contacts do not intersect with each other, for example, by using a multimeter.
  • Having finished with the connection of wiring, you can do the power unit depending on its value.


    In addition to the described, you can enter and somewhat different.


    When the adapter you choose is somewhat more powerful than the original, it is worth a special care to prevent overheating of the components of the laptop and directly the battery itself.

    On this, in fact, with the way you can finish, since after executing the recommendations it will remain only to install the battery and wait for it to fully download.

    Method 3: Use USB ports

    As you know, today a sufficiently large number of features provide standard USB ports that are literally on any portable computer. Such additional possibilities can rightly include charging the battery without using the original charger.
