Today in stores without problems you can find mobile devices with a fairly large capacity of your own battery, but still many people think about the need to buy Power Bank for smartphone. Modern gadgets, from the point of view of the duration of autonomous work, was far streaked forward from their first sensory analogues. Almost all of them can work in the active mode of operation during the light or working day, but many users are clearly not enough.

A long journey in transport or vacation in nature can lead to a complete discharge of the battery in the absence of the possibility of filling out its charge. How to deal with this situation?

Of course, you can try to switch to strict savings mode by using various settings. Failure from bright backlight, restricting the processor and the Internet will allow for several hours to extend the autonomous life of the smartphone, but it really limits the user. For the same purpose, you can try to buy an additional regular battery. But it will be extremely inconvenient to charge it, since it will have to remove the cover and disable the current battery, which will reset many settings. The owners of the "unsubstantiated" smartphones will not be able to help this option.

Fortunately, the need to significantly increase the service life of telephones could not remain unnoticed by electronics manufacturers. Today they filled the market with such devices as an external battery or Power Bank. This decision immediately liked the users, because Power sources are characterized by compactness, versatility, affordable price and decent capacity. In this article, we will consider all the nuances with which you need to meet to understand what Power Bank to choose for a smartphone.

Video review:

Power Bank Concept and Design

The modern Power Bank is a universal external battery consisting of a block of batteries combined into one case.

The devices can be further supplied with specific interfaces, charge / discharge indicators and other features. The number of batteries, their quality and capacity define the main differences in the chalk, presented in a very wide variety. We must not forget that the Power Bank for the smartphone is in a variety of external execution, as for the materials of the case and its design.

What a container is suitable for me

To answer this question, you must first get acquainted with its technical side. Inside the POWER BANK case, several lithium polymer (Li-POL) or lithium-ion (Li-ion) batteries are usually hidden, the capacity of which is measured in milliamper-hours (mAh). The technology of production of such batteries provides a low level of self-discharge, long service life and excellent indicators of specific energy intensity. It is necessary to understand that with the growth of the overall capacity of the external battery, its dimensions and weight will inevitably increase.

To determine the specific model of Troublebank, you need to focus on the container of the "native" battery of the smartphone. You can get such information from the instructions for the device, the manufacturer's official website or directly from the marking applied to the battery. For example, if a 2500 mAh marking is detected on the smartphone battery, the Power Bank should have a capacity of at least 3000 mAh.

How much charging count

Choosing a Power Bank for a smartphone, you should not share the container of the external battery to the similar indicator of the standard. Many people, mistaken, come in this way to determine the possibilities of Deliban, but for such buyers physics prepared bad news.

We will not go into scientific details, you just need to take the fact that Power Bank for 9000 mAh will not be able to fully charge the smartphone battery, if its capacity is 4500 mAh. With such a ratio, a good result will be the possibility of autonomous receipt of 150-170% of the charging of the regular battery.

What is this happening? In any power element, the gradual process of self-discharge occurs. Over time, the actual capacity of the batteries is also reduced. All standard power supplies in the plibs give out voltage at the level of 3.7V, and the USB interface operates with a voltage of 5V.

To increase the voltage in the design, a special fee is applied, but its efficiency, although approximate, but not equal to 100%. In the smartphone itself, there are also technical points responsible for the charge leakage. The combination of listed factors explains that even the highest quality Power Bank has losses at a level of 20-30% of the nominal value indicated on its label.

In search of ideal

Some people may seem that the more Pavebank has a capacity, the better. In practice, it is not. But how to choose an external battery for a smartphone?

As in any other matters, when choosing Power Bank, you need to focus on your own needs. Of course, an impressive container will help several times to charge the owner's device and his friends. But the owners of such an external battery will have to come to terms with the fact that there will be a device to be worn with them, which will not fit in an ordinary pocket.

On the other hand, the full charging of the smartphone is not always required, because It may just miss time. In such a situation, the best assistant will be a small and light pancake, made, for example, in the form of a keychain. Such a compact battery is quite capable of supporting the phone battery until it can be charged from a stationary source.
The weight and dimensions of a small assistant are practically invisible, unlike chalk, with a capacity of more than 10,000 mAh.

An interesting solution may be an external battery for Power Bank smartphones made in the form of a telephone cover. It is impossible to say that this is a universal version, because The case must correspond to the size of the case of a particular device. But on the other hand, the solution to buy an external battery for a smartphone of a similar type allows you to simultaneously get the protection of the device and an additional reserve of energy. In addition, you will definitely not for sure at home or at work, but you will have to come to humble with increased overall dimensions.

About what else you need to not forget

Important factors affecting the choice of external battery for a mobile device can be grouped as follows:

• charging current;
• connection interfaces;
• features of Charging Pavebank;
• charge indication.

Charging current is one of the most important technical characteristics of Delibank. Most devices presented in the market are capable of providing current in the range of 0.5-2 A. To make the right choice, you need to focus on the current consumed by a smartphone. This information can be found in the instructions of the phone or on the marking of the "native" charger for it. If this indicator is 1 A, then you need to buy Power Bank, which gives a similar or greater current strength. Buying a battery with a smaller current output is not a critical error, but in this case the smartphone will be charged much longer.

If it is decided to buy a turn of a large container, then you should give preference to models that have two and more output connectors. The charge current in these interfaces can be different, for example, the first connector will be marked "1a", and the second "2a". This does not mean that the total external battery will be able to provide an output current at 3a. Thus, the manufacturer offers the owner to use the most suitable connector for a particular device.

If you simultaneously connect several devices to this Pavebank, then at each output the device will receive half the maximum current output. In any case, the Power Bank of a large capacity with two exits for charging is better than an analogue with one connector.

The overwhelming majority of modern mobile devices for charging use the MicroUSB interface. The corresponding cable is not always included in the package of the battery, and if it is, it is often very short that you need to take into account when buying. If there is a need to charge old devices, for example, the Nokia phone, then it is worth looking for a chalk, which includes a set of adapters for once popular electronics with proprietary charging connectors.

It is important and how the external battery itself will be filled with a smartphone itself. It is better to abandon batteries that use own types Connectors, but prefer the product with a common microUSB. This will allow you to charge the autonomous power source almost from any smartphone or computer.

To buy an external battery for a smartphone and do not regret, you need to pay attention to the charging current of the battery. Here the rule is true: the more, the better. The charging current of the beliefs itself may be a critical characteristic for its normal use. For example, the capacious Power Bank for 20,000 mAh with a current of charging 500 mAh will fill its charge for 40 hours, which will definitely do not like the future owner.

The market is actively moving external batteries with built-in solar batteries. This additional element should be perceived, rather as a marketing trick. In practice, the sunny element on a clear day can compensate only to the natural self-discharge of the battery. Therefore, it is not worth overpaying for the solar panel, but it is better to pay more attention to the charge indication method.

Advanced devices can demonstrate a charge balance on a special display, but the LED indication will be sufficient. The last option, although not so accurate, then it is more reliable and energy efficient.

Conclusion: buying ready

Perhaps this instruction will also help you decide on the choice:

What unites all smartphones and tablets, no matter how modern and advanced are they? This is a weak place - always insufficient battery life and the ability to discharge at the most inopportune moment. Even the prudency of some users cannot cope with this "Achilles Fifte" and obsession to always leave the house with a 100 percent battery charge. An unexpected situation, a delay at work or on the way - and you stay cut off from around the world, and after all, to save the situation could be an external portable battery. There are thousands of them in the modern market: from the frank junk to very serious and reliable devices. Let's try to figure out how to choose an external battery that corresponds to the declared characteristics and fully responded to your requests. Bonus - the best Power Bank 2017, presented in the domestic market.

What is Power Bank: Little Liccess

Power bank., he is an external battery, it is a portable or additional battery- This is a small portable battery, with which you can charge a number of gadgets: smartphones, Tablets, Cameras, E-Booksand others who can receive energy via a USB cable. The battery itself periodically needs to be charged from a socket or computer, which accumulated energy it saves for a long period, so Paver Bank can be easily taken to work or study, on a trip, and even on the edge of the world - it will save when accessing the outlet and Electricity in it for any reason no reasons.

Inside Power Bank is multiple batteriesconnected to the controller board. The board also contains connector or connectors for connecting gadgets. Compatibility with a number of mobile devices is achieved through the use of a universal USB 2.0 connector.

An external battery can be any color, shapes and sizes - here manufacturers make us happy and offer many of the most different options to be and functionally, and the eye pleased. The housing can be made of plastic, polycarbonate or metal: In terms of practicality, all options are almost the same, but the metal case will make the battery somewhat harder.

The higher the battery capacity, the more weight will be - Do not buy on the model, in the characteristics of which are declared 20,000 mAh, and the weight is about 100 years old. If you plan to use the smartphone while charging it from the battery, it is better to choose the most ergonomic and comfortable battery. If an external battery is needed only to reach up to normal charge, you can choose a compact model with a slight weight. Some of them are even implemented in bracer format.

It is appropriate to mention existence cases batteries. In fact, it is the same external battery, and his functions have the same, but its substantial minus is sharpened for a specific model of the smartphone, and there are few practicality in this solution, so you cannot charge other gadgets.

Battery type in an external battery: Li-Pol and Li-Ion

Often buyers who wonder how to choose an external battery, completely reset the type of battery used, distracting other characteristics. The durability of the device and its functionality depends on the parameters of the batteries used.

In modern Paver Banks are used two fundamentally different types of batteries:

Battery capacity - the most important indicator

The first thing that all those who are going to buy an external battery are its container. This is the main characteristic of the battery, which suggests how many times and what technique it will be possible to recharge it. It is not necessary to chase a record high indicators - to start, decide on scenarios of use:

There is no point in taking a battery with a capacity of less than 4000-5000 mAh - there will be no special savings in terms of special savings.

Manufacturers sometimes love several exaggerate the real battery capacity. Often, Chinese companies are sinning without a loud name. There are scinting cases when a battery with a claimed capacity of 58,000 mAh is supplied in a light case (and it happens, see the photo below). If you buy an external battery in the store, you can take with you USB-Textright battery capacityTo check the stated numbers. It is worth such a tester in Chinese online stores 2-3 dollars.

Important! Remember that the manufacturer reports the capacity of the battery taking into account the voltage of the built-in batteries of 3.7 V. When the gadget is connected, the power transmission comes with a voltage of 5 V, and then it is converted to a smartphone again with a voltage of 3.7-4.2 V. Due to the double transformation, part of the energy is lost, and sometimes losses can reach 20-30%. Therefore, do not be discouraged if the battery per 10,000 mAh can charge the tablet with a similar capacity only by 70-80% - while this is the norm and technology costs.

Current power - second important indicator

If you do not go into details and technical moments, then the higher the power of the current, the faster the gadget will be charged. from a portable battery. If you select an external battery, be sure to check with which power of the current you can charge your smartphone or tablet to not harm the gadget. Information must be specified on a complete charger.

There are models smartphones with charge controllerwhich limits the current strength. For example, the Sony Xperia Z3 controller has a limit of 1.5 A, and if you connect it to the battery with a port at 3 A, the current will be limited, and the smartphone will still receive its 1.5 A - these are security measures provided by the manufacturer.

You can also find portable batteries that support function. fast charging. When it is used, the voltage increases and the current is reduced, due to which it is possible to fill in 30-40 minutes, on average, about 50-60% of the smartphone battery (accurate data depend on the parameters of the Pauner Bank itself and the gadget).

Incorrect conditions for transporting and storing the battery can be negative to say on its real capacity.

Number of ports

From an external battery with multiple outputs and a small capacity, there will be absolutely no sense for obvious reasons, so there is no point in paying attention to such models. If Pouver Bank has several ports, then it will be possible to use them normally if the capacity is at least 10,000 mAh.

Another nuance. Different ports, in theory, are intended for simultaneous charging smartphone and tablet, so often the manufacturer supplies them to different current output power, for example, 1 and 2 A. However, a value of 2 A is achieved when only one device is charging, so when connecting two gadgets, most likely, both ports will be given 1 A.

How to charge Power Bank?

Not only is the external battery loses energy, charging your gadgets, so it is also subject to the process. self-discharge. When you do not use the battery, it loses an average of 5% charge in two weeks. Moreover, the battery capacity has a property to decline over time, especially if the device is actively exploited: per year a quality product loses 15% of the capacity, and cheap models are all 35%. For checking level control All batteries are supplied with LED indicators (3-4 light bulbs). Advanced option - a small display, which displays the exact charge of the battery in percent.

By way of charging External batteries can be divided into such groups:

• those that eat only from the USB port of the computer;
• those that can receive energy and from the computer, and from the network, connecting to the usual outlet.

What do you think the option is more convenient? Naturally, the second. Actually, that is why the first type of batteries has almost completely disappeared from the sale. Remember that the device from the computer is much longer, and the presence of a USB Type-C port to speed up the process. Some Paver Banks can be charged in record time thanks to quick charging features.

Interesting option - charging with solar cells. While it is to say that the energy of the sun will be a full-fledged power supply of an external battery battery, early, but compensate for the self-discharge located on the end of the device the solar panel will be able.

Pay attention to external batteries with flashlights. They will be useful in case of disconnection of electricity and trips to nature.

Another point. Most mobile gadgets are equipped with the MicroUSB connector, and manufacturers often complete their devices with a universal cord, and Apple gadgets from Apple and relatively old technology better pay attention to the model with a set of universal adapters. Most users can not worry, as it will be possible to use a shoe for charging, which comes with a smartphone.

Best Power Bank 2017: Dozen of the most powerful

When choosing an external battery, it is better to trust the products of eminent brands: it is more likely that real characteristics will correspond to the stated, and the battery will accurately live for several years.

Reading time: 8 minutes

Despite the numerous developers attempts, make mobile devices more comfortable for users, the problem of quick discharge of the inner battery remains open. With the usual use of a cell phone, standard charging is enough for 12 hours. People whose work is associated with regular phone calls and Internet access, can land the phone for 5-6 hours. Execution unpleasant situation will help external batteries for smartphones rating of the best models from the market offered on the market? What external battery is better to buy? Let's try to figure out.

Principle of operation

An external battery is called Power Bank, which means "Power Bank". A portable device is a complex mechanism from numerous parts hiding under the case. In the power supply there is one or several connectors at once for connecting mobile phones to it. Usually, these are standard USB ports. The case of the bank is made of silicone, plastic or aluminum.

Connecting to the battery, the smartphone starts the charging process. Depending on the Power Bank capacitance, you can charge the phone completely at all times, and some devices are capable of recharging two or more gadgets.

How to choose an external phone battery

Before making the purchase of a power supply for your mobile, you need to familiarize yourself with the main characteristics of Power Bank.

1. Capacity: The most important moment in the choice of "charger" is its capacity. Than it is more, the longer the battery will be able to work. The optimal solution will be the container from 600 to 1500 mAh.
2. Current: the current is important, because it is more powerful, the faster the phone will be charged. For modern gadgets, it is better to choose batteries with indicators from 800 to 2000 mA.
3. Size: It is worth understanding that the more powerful an external battery, the more larger. This is due to the fact that it contains more power parts.
4. Design: Today, the Power Bank market is a diversity. In stores there are classic square and rectangular batteries in rigorous colors, as well as bright devices made in the form of fun toys.

Additional functions

After 2-3 years of work, almost any smartphone loses the battery capacity. In this case, during the day, recharging may be required at least once. On the road, on a business trip, this problem becomes especially acute. This is relevant and in marching conditions, where communication is especially necessary, because the phone may be needed in an unforeseen situation. To solve this problem, a separate class of charging devices appeared - Delibanks.

What is needed?

POWERBANK (POWER BANK) is an external battery charged from the network, and the electrical charge store for another device. The battery is very convenient to use and requires only the presence of a USB cable with a MicroUSB connector (or any other plug under a specific device).

The main advantage of Delibank - Compatibility with almost all devices and gadgets. The simplicity and compactness of Delibank made it almost a thing of the essence for those people whose work is related to travel. In addition to the phone, it will help to charge: wireless Camera, Wireless headphones (although at least), smart watches, autonomous lamp, amplifier (repeater) WiFi, electronic cigarette and other gadgets. By the way, and numerous "" It is convenient to charge from the compact "banks" than to be tied to the outlet.

How does the hard drive work?

The battery converts the voltage using the 3.6-\u003e 5V converter. Thus, at the output, the voltage is 5V, with the power of current to 0,8a. Charging the beliefs can be done through a network adapter, or from a computer via USB port (voltage 5V).

Varieties

As a basis for paniban, modern manufacturers offer:

1) Lithium-ion batteries (Li-ion)

Pros:

• large capacity (up to 3000 mAh);
• 3.6-3.7V output voltage;
• up to 1000 charging cycles;
• low weight and compactness;
• low self-discharge coefficient;
• no memory effect.

Minuses:do not like overheating, so it must be equipped with overheating protection.

2) Lithium Polymer Batteries (Li-POL)

Pros:

• flat or rectangular shape;
• low weight;
• large energy density per unit volume;
• no memory effect.

Minuses:

• higher cost;
• requires protection against overheating and fire (additional scheme);
• there is a possibility of a battery output with a very deep discharge.

1. From the capacity of the battery in Milliamper-hours (Mach), the view and dimensions of the charger depends. Turnibank Capacity Choose depending on the capacity of the gadget battery for which you buy an additional battery. For example, for a smartphone - from 2500 mAh, for a tablet - from 5000 mAh.
2. None of the plungeib can give its capacity by 100%! Consider this with your calculations, how many times you can charge your device using this device without further charging.
3. The strength of the current is an important moment when choosing a panibor, as the batteries with greater current (2a) will be charged faster. For some users, time is extremely important. The current range of the current pot models presented on the market: 0.5-2a.
4. If you have to recharge several devices at once, pay attention to the number of USB ports that the external battery is equipped.

In the chambers of two ports (1a and 2a) port 1A is provided for phones and small devices (for example, Bluetooth headphones), port 2a - for professional cameras and tablets.
