Nowadays electronic gadgets are used everywhere. They are needed for work, communication and entertainment. With active work, modern mobile phones and tablets are quickly discharged. Even if you always carry it with you Charger, it is not always possible to include it in the network. A portable charger for your phone called Power Bank will help you not to be left without connection at the right moment.

The device is called differently - external battery, portable or mobile charger, portable charger. In this case, we are talking about the same thing - charging a phone without an outlet.

The advantage of Power Bank is that it can be used to charge electronic gadgets when other methods are not available. This can happen not only in situations where there are no outlets nearby or they are all busy, but also during long trips, travels, and even hiking trips. For those who like to often get out into nature, there are special external batteries equipped with a solar battery.

Power Bank is a battery that must be pre-charged and then used to power other devices.

The portable charger is small and lightweight, making it easy to carry around in your bag. Gadgets are connected to the Power Bank through a cable connected to the USB connector, which makes an external battery universal device... It can be used not only to charge the phone battery, but also for tablets, cameras, laptops, players.

Some models of the portable device have more than one USB connector, which allows you to charge several gadgets at the same time.

More about capacity

Capacity is a characteristic that indicates how long a portable battery can be used to power other gadgets without recharging. Most portable devices have an indicator that flashes when they are low. To use PowerBank again, you need to charge it in one of the ways - from the network, laptop or computer. Charging takes place through a special micro-USB connector on the case.

Most of the demanded batteries have a capacity in the range of 1500-20000 mAh. How much capacity is needed depends on the devices that PowerBank will be used to power. If you need a battery to charge your phone, a device with a lower capacity is suitable than for recharging a laptop or photography equipment.

The weight of the portable battery directly depends on the capacity. You should know this in order to avoid buying a fake. On the Internet, you can find offers in which the low weight and low price of the battery do not correspond to its capacity. The 5000 mAh increase in capacity makes the model weigh about 100 g more.

We calculate the number of charging cycles

PowerBank can be used to recharge electronic devices as many times as its capacity exceeds the battery capacity of the charging devices. When choosing a portable battery, it is advised to focus on several charging cycles. To do this, you need to multiply the battery capacity of the gadget that you plan to connect to the portable charger by 2-2.5.

For example, if you are looking for a portable charger for mobile phones, the battery capacity of which is 2600 mAh, you should not buy an external battery with less than 5200 mAh.

Please note that PowerBank will not charge gadgets with more battery capacity than the external battery.

It should be understood that the portable battery will not be able to fully charge the device if the capacity of their batteries is the same, since the PowerBank battery is consumed to keep it running.

Charge currents

The strength of the current affects the charging speed of the devices. In external batteries, USB ports for 1 A or 2 A are common. A 1 A plug is needed to charge phones, smartphones, players, e-books. The 2 A USB port is suitable for large equipment - tablets, cameras, laptops.

There are PowerBank models with multiple connectors. Most of these chargers have ports with different amperage.

Mobile batteries are equipped with controllers that limit the supply of voltage to devices with a weak battery, so the player or phone will not be damaged if connected to a 2 A connector. Otherwise, when large equipment is connected to a connector with a weak current, the charging process will be slow.

Battery type

There are 2 types of batteries: lithium-ion and lithium-polymer.

Li-ion devices

Lithium-ion chargers are more common on the market. This type of battery matches most batteries found in modern mobile phones.

Li-ion PowerBank is inexpensive and can charge most tablets and smartphones.

The disadvantages of this type of battery include the risk of damage from overcharging or overheating. There are PowerBank models that provide automatic shutdown in such situations.

Li-polymer devices

Lithium polymer chargers have an internal structure that allows you to get more battery capacity with less weight compared to Li-ion devices.

Li-polymer chargers have a higher price. This is due to the need to install a special board to ensure the operation of the device, which has a complex internal circuitry. The batteries are also equipped with an overheating design.

Cheap lithium-polymer chargers can neglect the installation of additional cells, which can quickly deteriorate batteries.

How to choose the right one?

To choose a good external battery, you need to build on the needs of the buyer. You should understand which gadgets you plan to charge, how much and how often.

There is no point in overpaying for PowerBank with large capacity, if you choose an external battery for your phone such that it can be charged at sufficiently minimal rates. To charge a laptop, you need a device of at least 20,000 mAh, less capacious ones simply will not work. It should be borne in mind that the larger the capacity, the more weight, and some models may not be comfortable to carry with you every day.

When using tablets and photographic equipment, it is better to opt for models with a higher amperage, which will provide fast charging.

If you need to charge the battery of your phone or other gadgets that do not have a USB port, choose a model that includes adapters for connecting old-style devices.

Portable chargers can be made of plastic or metal. In the second case, the phone charger will be stronger and less prone to scratches, but its price and weight will be higher.

You can find PowerBank with an unusual design. They can be made in the form of various toys, animals or any other shape. It should be borne in mind that such decorative devices, due to the original appearance, have a higher cost, although they may not have high performance.

If you need to use the device while traveling, you should pay attention to devices with a built-in solar battery. They will make it possible to recharge the phone for several hours even in extreme conditions where there is no electricity.

Sometimes it may be necessary to use the device while being powered by PowerBank while standing or on the move. In this case, it is better to choose a small-sized battery that will allow you not to break away from the case - holding such a device in your hands is not difficult.

Some models are equipped with additional elements that can make the work more comfortable - LED indicators, screen, flashlight.

Top portable chargers

The popular model is Xiaomi Power Bank 2 20000 mAh. This device provides the best value for money. Has a plastic case. A 20,000 mAh battery and 2.4 A connectors allow it to be used not only as a phone battery charger, but also for tablets and other more capacious equipment. 2 USB ports make it possible to simultaneously power multiple devices.

ASUS ZenPower 10050 mAh ABTU005 is a portable phone charger made of metal and equipped with an LED that will notify you when the device is running low. Features allow you to charge smartphones, including newer iPhone models, which have higher capacity.

TP-LINK TL-PB10400 is a compact model, the size of which allows you to use PowerBank on the go, while on the road a built-in flashlight can help out. Has 2 ports for connecting devices for 1 and 2 A.

One of optimal options The portable phone battery charger is SONY CP-V10. Its advantages are compact. The 10,000mAh battery and 1.5M current output keep the price affordable. A light indicator adds to the comfort in use.

This is all physics, I am not strong in it, but the fact is the fact. First of all, when buying, we pay attention to the capacity. We calculate 60% from it and get the exact number of charge without losses, which will go to the device itself.

Don't be fooled when buying at a low price and a large number of milliampere hours. These gadgets are pretty mediocre. Remember, a good power bank with 20,000 mAh should not cost less than 2,000-2,500 thousand rubles.

Current strength

It depends on the current strength how long the wireless charger will charge your gadget. Usually smartphones need 1 amp for charging, and tablets 2.

Weight and size

Why is this an important criterion when choosing? It's simple, portable charger should be:

• compact
• not too heavy
• and have a user-friendly design (the thinner the better)

Why are you buying it? To take with you on a hike, on a trip, on a picnic, to the country and so on. In general, in the place where there is no way to charge from the outlet.

Of course, the power bank should be small. Who wants to carry a stone weighing several hundred grams in their bag? But there are two sides of the coin. The smaller the device you buy, the less capacity it has.

You need to look for a middle ground. Moreover, manufacturers take into account such parameters and do their best to combine high performance and compactness in one device.

Number of USB ports

Imagine you are on a camping trip with your friend. So you sat down to have a snack, relax, go to the social. network or watch a video clip ... But bad luck, as luck would have it, the batteries on your smartphones are discharged. And then you remember that you have a portable battery!

With a contented look, you take it out of your bag and put your gadget on recharge. Your friend certainly feels left out. Well, right, you had to think in advance and buy yourself such a device ...

Of course, you are a kind person and you will not do that, but just share the second usb port with a friend. No wonder that many models are equipped with it. By the way, the manufacturers are not limited to two. You can often find more.

Battery type

The battery itself in the device may be ( click to open description):

lithium ion

In appearance, it is similar to conventional finger batteries and is the most optimal in terms of price and quality. The lithium-ion battery lasts for about 1000 charges, then the power starts to drop and the mAh disappears.

lithium polymer

May take on a flatter shape. A lithium polymer battery will last much longer (up to about 5,000 charges), and this will increase its price. Such batteries are less common in banks.

Removable battery

Some devices have a removable battery function. That is, batteries that change as needed. Thus, you get yourself the case of the portable device, and you can always replace the battery yourself.

The advantage of such models is that they will last much longer. Over time, any power bank wears out and its charge becomes less and less. In the case of this variant of the device, you can always replace the battery with a new one and, voila, you have a brand new device.

But there are also disadvantages. Such a power bank operates at a low amperage, and this increases the charging time.

Indicator presence

In addition, you can find a light indicator on the device. Which indicates how much charge is still left. You can also find a device that has a display.

Buyers note that it is much more convenient to see the charge as a percentage on the display than indicator lights. But there is also a minus. The screen also consumes some of the energy that could go into the gadget.

Automatic shutdown

One of the important functions of the power bank is automatic shutdown. It protects against short circuits, as well as against sudden power surges that can damage the devices being charged.

In addition, this function prevents waste of energy. For example, you can put your gadgets on charge at night and not worry that after a while you will need to wake up and disconnect the battery.

Additional features and accessories

For example, for hikes, you can purchase a power bank with a flashlight and a hand warmer. Some models are even equipped with a wi-fi connection and an input for a flash drive. In short, what will not be invented and as soon as the manufacturers will not decorate the device.

You can also choose an adapter for charging and a protective case for your external battery. Basically, the covers are silicone, they will protect the device from dirt, dust and possible water ingress. The adapter will help you charge the power bank 2 times faster.

Which company to choose an external battery?

There are a LOT of companies producing these devices. Among them there are both popular brands and those unknown to anyone. Basically, all devices are made in China. For this reason, I see the point of ordering the device there.

• Firstly, you don't overpay extra money
• Secondly, shipping to Russia and the CIS is mostly free

At the exit, we get a device from the same China, but much cheaper than in a city store. Of course, there is a minus, since you will have to wait for the parcel for about a month. But, for example, it doesn't scare me at all. In any case, in terms of money, you remain in the black. And if, then the purchase will become even more profitable.

I picked up several models of the power bank from Chinese marketplaces such as GearBest and Aliexpress. I will also highlight a couple of well-known companies whose devices are most popular around the world. Here are the brands we'll be looking at in this article:

• Samsung- Korean company known all over the world
• XIAOMI- a popular Chinese brand
• Canyon is a Dutch electronics company
• Baseus- a young Chinese company
• USAMS Is another Chinese brand that produces electronics and accessories
• Yoobao- high-tech electronics from China

A year ago, I did not understand anything about gadgets at all and decided to buy myself a portable battery. Then no one told me how to choose a power bank for a smartphone. I spent 500 rubles on a battery, the capacity of which, as stated, is 8000 mAh. But in fact, the milliampere hours turned out to be only 3000.

Yes, that was my bad buy ... My iPhone 6S will never be fully charged with this battery. Only 60%. Why am I writing all this. If you want to buy a really high-performance device, then less than 1000 or even 1500 rubles is not worth spending. Otherwise, you will have to pay twice and buy a second device with more power, as I had to do.

I hope this article was informative and helped answer the question of how to choose a portable charger for your phone, tablet and other gadgets.

The phone is always discharged before an important meeting or during a business call, and the tablet “dies” a couple of minutes before winning the game. A portable charger will help you avoid unpleasant situations. How to choose such an external battery so that it has the maximum number of charges? Fit for both phone and tablet? In the overview you will find the main specifications, which you need to focus on when choosing, and reviews of different battery models.

Power Bank - what is it?

Until 10 years ago, phones worked perfectly without recharging all week. Today the device performs so many functions that its battery needs to be recharged regularly. In order not to ask employees for charging and not to run in search of an outlet in the mall, it is better to just stock up on a portable charger. The battery can be carried in a pocket, bag, or carried in the glove compartment. But how much it can weigh and whether it is capable of charging one or 2 devices several times is a separate conversation.

Power Bank, or external battery, is a portable power source for charging any gadgets. It consists of batteries (from 2 to 10) connected to the controller board. The battery has 1 or 2 USB ports to which you can connect a phone, tablet, camcorder, photo camera, etc.

The device works like a storage device. First it charges from the mains, then generously shares energy with any connected devices.

Before you start choosing a model, you need to decide:

• what are you going to charge with the battery? How many devices?
• How many times a day will you need a portable power supply?
• what size and function should your battery be?

External charger capacity

In practice, buyers choose a portable battery based on size, design and body color. Then they buy a new one if this one does not suit. It is much more practical to immediately take into account the main technical characteristics. The most important of these is the capacity of the device.

The main task of the accumulator is to give off the accumulated energy. The question is how much Power Bank can hold and give away, this is the capacity. The capacity is usually indicated on the case or in the documents of the device.

Advice. If you liked an external battery with impressive capacity and relatively low cost, then most likely it is a fake with low-quality components.

The difficulty is that the amount of energy received and transmitted is slightly different, because part of it is lost during the transmission process.

Some unscrupulous manufacturers, taking advantage of this moment, indicate the amount of energy received, not given away. Experiments have shown that the average number of transmission losses is 20-30%. This means that a charger designed for 1000 mAh can charge a smartphone at 700-800 mAh. When buying, it is almost impossible to check this, which means that you need to choose products from well-known brands.

Attention! It is better to purchase a charger with a capacity that is twice as large as the battery of a phone or tablet.

If the phone has a battery with a capacity of 2800 mAh, a charger with an indicator of 5600 mAh or more is suitable for it. In the event that you charge two devices, then you need to add up their capacity and multiply by 2. And when buying, be guided by this figure.
The average option can be considered a Power Bank with an indicator of 6000 mAh, with which you can charge a smartphone for 2-3 days. A universal version with 12000 mAh is suitable for phone and tablet

Outgoing current supplied to the connector

The output current is the second parameter that must be taken into account when choosing. The fact is that the current strength partially affects the rate at which the device recharges.

Attention! For Apple tablet owners, a 2A charger is suitable. This indicator is usually indicated on all portable batteries next to the connector.

Standard USB port with 1A amperage for phones and 1.5-2A for tablets. When buying a battery, you need to make sure that the charging current is consistent with the device you are going to charge. Or choose a universal battery.

Apple iphone, camcorders and players match with the battery, which has a current strength of 1A. For the iPad, this figure rises to 2A. This means that if you are going to charge a phone and a tablet at the same time, you need to select an external device with two connectors, 1A and 2A.

Theoretically, you can charge a smartphone with 1A through the 2A connector and it will "come to life" faster. Or, conversely, charge the tablet through port 1A, which will be much slower. But it is better to follow the recommendations of the device manufacturer.

Input current refers to how quickly the battery itself charges. The same principle applies here. The current strength must be equal to and exceed the capacity of the battery, then it will be powered at a high speed.

Features of the case of the portable charger

On the one hand, I want to use a light, compact battery that fits in my pocket and won't drag it out. On the other hand, a large capacity is required for full, comfortable charging. How can you find the optimal ratio here?

Attention! Experts warn that small, cute, high-capacity batteries do not exist in nature! The higher the capacity rating, and the more connectors on the charger, the larger and heavier the device itself will be.

The way out of the situation is simple, you need to choose a Power Bank based on your individual needs. Count how many times a day you need to charge one or two devices. In accordance with this indicator, and purchase a battery. Experienced users are advised to add a small margin to the resulting figure. In case you decide to go on vacation with your friends and share the exercise with them.

Additional functions of the portable charger

Often on sale you can see batteries with additional features... Let's list the most popular "chips":

1. Charger with flashlight. A battery like this can come in handy if it is so compact that it fits in your pocket or in the nearest compartment of your bag. As a flashlight, manufacturers usually use an LED that works at a minimum of energy and is not able to drain the battery.
2. Battery with built-in solar battery. On the one hand, this solution is very environmentally friendly, because the Power Bank can be charged not only with the help of a computer or an outlet, but also with the help of sunlight. The downside is that such charging lasts at least 3-4 days, subject to good weather.
3. External charger plus Wi Fi router. Such batteries combine two functions: they charge and work like a router, that is, they distribute the Internet.
4. The user may find useful the function automatic shutdown nutrition.
5. Any batteries have a built-in charging indicator in the form of "sticks", which over time may give incorrect information. A digital indicator with a display is much more accurate and reliable, but adds about 20% to the cost of the battery.

In terms of design and color, portable chargers can be bright and interesting or austere, business-like. For example, the Gmini company produces batteries that look like stones.

To questions like: "What portable charger better to buy? " experienced owners of high-quality devices unanimously advise not to save, but to purchase batteries of proven brands. A lot of examples and photos with a battery and two bags of sand in a beautiful case make you doubt Chinese-made products.

Experts believe that the average cost of a quality Power Bank is from $ 40. Buying an external device on the Internet can be an order of magnitude more profitable, but it is still better to buy it in a store where all the documents and a guarantee are provided.

External Battery - Portable Phone Charger

What is Power Bank

Essentially, the Power Bank is a battery. An additional battery that has a larger volume and is capable of storing more charge. Thanks to the charge distribution function, it is able to transfer it to other mobile devices.

External battery: advantages

Power Bank is an irreplaceable thing that allows you to charge mobile device in a situation where there is no access to stationary charging from the network, computer or laptop.

The portable charger is easy to use, small in size and light in weight. It is universal and suitable for any mobile device.

You can be sure that thanks to this small box, your smartphone or tablet will always have an additional charge on long trips. The main thing is not to forget to charge the external battery itself and take the USB cable!

Which Power Bank is better to buy

Where to buy Power Bank

To search for an online store where to buy a portable external battery (Power Bank) at a good price, you can use specialized online trading platforms.

A portable charger is a very useful thing that every modern smartphone owner will need. In particular, PowerBank (poverbank) will become an indispensable device for those who like hiking and long journeys. The choice of models is simply huge, so finding an option that would completely suit you in terms of basic parameters and cost is not difficult. Below we will talk about what you need to consider when buying an external, and which of its characteristics are most important.

Charger capacity indicator

How functional the power bank will be depends on this parameter. It also has a significant impact on its weight and price. Capacitance units are ampere-hours. (abbreviated designation - mAh in Russian and mAh in English).

How do you know which PowerBank capacity is best for you? In this case, an important role is played by which gadget will be charged most often. If it is a smartphone, then the indicator of the capacity of the external battery should be at least 1.5 times higher than that of the battery. It is desirable that this parameter be higher and allow at least 3 times to charge a completely dead phone. The efficiency of any portable charger is less than 100%. This indicates that energy losses cannot be avoided during the charging process. It is difficult to name their exact volume. It all depends on the quality level of the installed battery. In other words, having a PowerBank with a capacity of 5 thousand mAh, you cannot use it to fully charge a 2.5 thousand mAh battery twice.

Pay attention to the little things

Sometimes the connectors are poorly made. In particular, this applies to power banks that are produced by little-known firms. Reliable manufacturers do not see the point in saving on cheap parts, but small ones do not even shrink from this. Take a close look at your portable charger before purchasing to avoid getting yourself into trouble. If the connectors seem flimsy to you, then it is better to refuse such a purchase, because in the future you will experience significant inconvenience when connecting a smartphone or other gadgets.

Complete set of charging models for phones

Very often the package includes several adapters in addition to the external battery itself. Among them it is necessary to highlight:

• Micro USB designed to connect modern tablets and smartphones.
• Lightning compatible with Apple appliances.
• Mini USB, thanks to which you can charge old phone, player, camera, etc.
• Outdated adapter for gadgets from Apple.

As you can see, the list is not so bad, because there will definitely be a cable in it that will fit the device you have, but it is better to refuse to use it. The fact is that the quality level of any of the adapters listed above usually leaves much to be desired. It will quickly break down, and can also adversely affect the condition of the gadget. Thus, if you purchased a power bank from a little-known manufacturer, then be on the lookout and do not rush to connect cables that can only harm.

The new charger comes with network adapter to him. It will definitely come in handy when you need to connect both a smartphone and PowerBank to an outlet. In this regard, it is better to have two adapters with you.

Availability of indicators

Some portable battery models have built-in indicators. Using them, you can find out information about the remainder of the stored energy, or the time left until full charging.

An excellent choice would be a model equipped with a small display on which data on the state of the power bank will be displayed. Despite this, it is not worth making the presence of indicators one of the mandatory requirements for a portable charger. If you find a portable battery that suits you completely and is equipped with flashing lights, then feel free to buy it, and do not look for a device with a screen similar in parameters.

What should be the case?

The material from which the PowerBank case is made does not play any significant role. It serves an exclusively aesthetic function, so choose what you like. There is an opinion that a metal case will always be better than a plastic one. It is easy to disagree with this, because the most important thing is the "filling" and reliability of the portable battery, and not its appearance... Meanwhile, we can recommend a power bank in the case, which is coated with "SoftTouch". It is pleasant to the touch and slightly rough. The main advantage is that the Soft-touch layer provides a secure grip and reduces the likelihood of the battery accidentally falling out of the hands. If we talk about the strength of the case, then it should be high, but the presence of a shockproof coating is not necessary.

Simple and stylish design at the 10 thousand mAh power bank from Xiaomi: metal case the corporate logo flaunts. It looks very attractive. There are also models with an unusual design. For example, one of them is PowerBank Emie Devil Doodle. This device costs about $ 50, but it works stably and looks beautiful. The only drawback is that it can only be purchased via the Internet by ordering on one of the Chinese sites.

PowerBank Manufacturer's Choice

This is a very important criterion that must be taken into account when buying an external battery. Meanwhile, this does not mean at all that you need to purchase an expensive model produced by a well-known company. Currently, Chinese powerbanks produced under well-known brands are in high demand: TP-LINK, Meizu, Drobak, Xiaomi, Sony, etc. In terms of sales, products from Xiaomi are in the lead. This company has established itself as a reliable manufacturer of not only portable chargers, but other "smart" equipment, such as pedometer bracelets.

It is not worth buying PowerBank of dubious production because:

• The difference between the capacity declared in the documentation and the actual one will be solid;
• The quality of adapters and connectors will leave much to be desired, which will cause significant inconvenience at the time of using the device;
• The likelihood of a quick breakdown will be noticeably increased;
• Problems with warranty repair are possible.

Are you looking for additional features?

The range of portable batteries is wide enough. In this regard, it will not be difficult to purchase a device that will have additional functions. Some power banks are equipped with card readers, Wi-Fi modules, memory cards, etc. Whether they are useful or not, everyone decides for himself. Most importantly, do not buy a battery that is too cheap or made by a little-known company, because such an acquisition will most likely only bring a loss.
