How to choose a good power bank?

As practice and my experience of an inexperienced buyer show, the choice of such electronics is based on a comparison of the capacities of different external batteries. This is not quite the right approach, because even the declared parameter rarely corresponds to reality. If you do not know how to choose a power bank, we recommend that you pay attention to the following nuances and recommendations:

  1. Optimal capacity. Here it is necessary to distinguish between actual and declared data, because the manufacturer indicates the power supply of the power bank itself, but the real energy transfer rate is always less than the declared data. So, if you have a smartphone with a 5000 mAh battery and you want to get a power bank with the expectation that you can fully restore the battery twice, you need to get it with a margin, not 10,000 mAh.
  2. Fast charging. In modern USB standards, the voltage is often higher than that of the converter, so some of the energy disappears without a trace. Also, if your gadget supports fast charging (in budget models, up to a third of the charge is lost). Therefore, you need to take mAh with a margin of 25-30% if you want to use the fast charging standard.
  3. Frame. Modern manufacturers are trying to surprise customers with a screen, bright design and a flashlight. Indeed, the issue of the stylistic component should not intersect with such parameters as the duration and quality of the elements.

What is the best bank for iPhone and iPad? In the case of Apple tablets, you need to focus on external batteries that support a current of at least 2A. Otherwise, you won’t be able to recover the large iPad battery. In the case of smartphones, everything is easier. Take into account the battery capacity and take it with a margin of 10-15%, and if the buyer has a gadget with fast charging, then with a margin of 25-30%. Is it worth buying a power bank on Aliexpress? Many Chinese models of external batteries are ordered from there in online stores, but they allow you to receive goods faster, sometimes taking a formal, sometimes large commission for this. But it is important to understand that some Chinese manufacturers on Aliexpress offer products that do not correspond to reality: they have poor useful power, different amperage, etc. What you need to know before buying a power bank? Always buy a power bank with a spare capacity. In particular, if you are interested in a device with fast charging.

What is the best external battery to buy in 2021?

Considering the power of modern gadgets, as well as the above facts, it is absolutely not worth saving on the power of such equipment. If you do not know which power bank to buy, focus on well-known brands. Also, if you are interested in a gadget with a progressive fast charging standard. Regarding our opinion:

  1. Best cheap external battery – Awei P9K;
  2. Maximum capacity external battery – TopON TOP-X72;
  3. A good model for charging an iPhone is the Apple MagSafe Battery Pack;
  4. The best power bank in terms of price and quality – Xiaomi Solove W5;
  5. Efficient PowerBank with wireless charging – Samsung EB-U3300.
