Choosing a good charger is not as easy as it seems. In this article, we will tell you how to choose the best power bank 2021, what you should look at first and how not to buy for a fake. In this article, we have collected the most popular mistakes of those who buy batteries without looking. Read and, as they say, shake your head.

1. To think that the best power bank charger is for sale on AliExpress

It is clear that the temptation to order from China a battery with a capacity of 10,000 mAh and a price of some 6-7 dollars from the first seller will be very strong. However, it is better to get over yourself and go to the store. In addition, not in an underground passage where exactly the same products are sold from AliExpress (but with a surcharge), but in some more or less large one. And pay $ 25-30 for a battery of the same capacity.

Why you shouldn’t buy cheap power banks on AliExpress? There are several reasons. First: from China for that kind of money in 99% of cases, they will send you a product of extremely low quality and low reliability. This in itself is unpleasant, but the battery is also a fire hazardous thing. The battery assembled by feet may one day catch fire, after which the day will immediately cease to be beautiful.

The second reason: instead of the promised 10,000 mAh in such an ultra-cheap Chinese battery, it will most likely actually be 7,000 mAh. Alternatively, 5000. Moreover, in especially neglected cases, even 2000. (In addition, this is the nominal capacity, but in reality, it is still somewhat more complicated, which we will discuss below.)

And the third: the above “overpayment” ($ 25-30 in the store instead of $ 6-7 on AliExpress) is not an overpayment, but just a normal payment for a high-quality 10,000 mAh external battery with a supplier’s warranty and a service life of several years. Anything that is cheaper is from the evil one.

2. To look for the best power bank brand, not the optimal capacity

Above we mentioned the 10,000 mAh battery. This volume can be considered optimal today – given the gradual increase in the average battery capacity of smartphones.

The point is that 10,000 mAh is the nominal capacity of an external battery. In fact, the efficiency of his work does not exceed 80 percent, and most often tends to two-thirds. In other words, if the battery reads 10,000 mAh, then taking into account leaks and converting energy into heat, it is capable of giving about 7,000 mAh to your smartphone. Or even less. This is enough to recharge a gadget with an average 3,000 mAh battery a couple of times.

Therefore, we recommend looking at models with a capacity of 10,000 mAh and, possibly, more (depending on your needs). Because a battery with a smaller capacity – say, 5000-6000 mAh – is enough for only one or one and a half recharges of the smartphone, which, you see, is not enough. For a tablet with a 4000-5000 mAh battery, an external battery labeled 5000 or 6000 mAh may not be enough at all.

3. To consider the brand name on the case as a guarantee

The presence of the best power bank brand logo on the case – Samsung, Asus, Huawei, Xiaomi and so on – guarantees the level of quality and reliability. However, at the same time, you need to understand that copying an external battery is much easier than, for example, a laptop or smartphone. Therefore, under the guise of a device of one of the listed brands, you may be sold something that has nothing to do with these brands. Therefore, do not think of it as an advertisement, we will give advice: batteries of large brands are best bought in their online or offline stores. Or at least large retailers that carefully monitor what they put on the shelf. Then you definitely do not run into a fake.

However, incidents sometimes happen anyway. Not so long ago, one fairly large and respected regional retail chain held a promotion: you buy a smartphone of a certain class – and you get a Xiaomi “bank” as a gift. In fact, it turned out that the Xiaomi batteries were … fake. Moreover, the retail network did not really know about it: the authors of the action were 100% sure that they were distributing the original.

4. To think that the best power bank charger should be made of aluminum

Different people have different attitudes towards spoiling the appearance of their gadgets. Someone, for example, does not care about scratches and scuffs at all (we envy such comrades). Nevertheless: batteries in aluminum cases quickly lose their original appearance, becoming covered with scratches, dents and so on.

We usually treat power banks with less fondness than the same smartphones, and we throw them into bags and backpacks with a bunch of solid objects. Yes, you can put a cover on the “bank”, but is it inelegant and strange?

In short, aluminum and metal batteries look very decent, but they are losing their presentation at the speed of sound. If you do not care – take just such a model. You will not regret. If you suffer from every scratch, then, probably, good old plastic will be better. It is more difficult to damage it in a bag.

5. Do not to look at numbers

A typical modern smartphone is equipped with a 2A charger. Some tablets are even 2.1A. Therefore, it is desirable that the USB ports on the external battery case give out exactly this current strength. Otherwise, the charging process will be extremely slow. So, we do not recommend buying models with 1 A. Today it is just fun for chickens.

The opposite is also true: it is worth thinking in advance, about how you will charge the external battery itself. If the battery capacity is the same 10,000 mAh, and the input current is only 1 A, then we congratulate you: such a battery will “feed” at the outlet all night. Maybe longer. So 2 A or 2.1 A is better.

We also recommend paying attention to power banks with fast charging systems. Now some models support Qualcomm Quick Charge of different versions – both for the return and for the receipt. It might be worth looking in their direction. However, there is one nuance.It is not a fact that your smartphone supports Quick Charge, and therefore, in practice, charging can go in normal (non-fast) mode.

6. To ignore the cable length

The problem is that the cables built into external batteries are usually very short – well, five, well, ten centimeters. Moreover, this means that using a smartphone while charging will be problematic. You will have to press the external battery against its back with your fingers.

I remember that at one time Samsung released a line of batteries with a retractable MicroUSB cable (we say goodbye to universality) and without conventional USB ports.

Today there are models on the market that have both built-in cables and USB ports.

Such options, in our opinion, are also not the most optimal. Because there is a certain type of plug on the built-in cable – for example, MicroUSB or Lightning. Moreover, that is all: if you have, for example, MicroUSB, then you cannot connect the iPhone to it. Whereas a regular USB port allows you to connect any cable with any plug. Therefore, when choosing from two options – “built-in cable + USB port” and “a pair of standard USB ports” – we definitely recommend the second one. It is more convenient and versatile.

7. To forget about indicator

Some overly economical battery manufacturers do not equip them with charge indicators at all. Which is very bad – go and figure out if the battery is charged or almost empty. Therefore, we recommend when buying to see if there is at least some indicator on the case.

The fact is, it has to be. Otherwise – torment and inconvenience.

8. To search for the best power bank for all occasions

Manufacturers often try to stand out by using some special chips. Here are some of them.

A solar battery is a useless option: you cannot charge a power bank with it, you can reinsure maximum against self-discharge in non-operating mode (and that is very, very unlikely).

Protection from water and dust is not stupid, but also of little use. It is clear that if you intend to charge smartphones at the beach or by the pool, then protection can come in handy. However, we do not recommend taking «off-road» batteries for every day: they are often larger and heavier than usual ones.

Flashlight … But the flashlight is different from the flashlight. There are flashlights of the “flash from a smartphone” level, and there is little sense from them. With the same success, you can highlight the smartphone itself. Moreover, there are batteries with powerful built-in flashlights, and they shine so brightly that you can safely read a book in a dark room under the light of a power bank. If your home is regularly cut off electricity – this option can even come in handy.

As a conclusion
