The Best Power Banks to Buy in 2021

A power bank is a portable battery that allows you to recharge a smartphone (or even a tablet or notebook) in case of need. There are various capacities and characteristics ideal for those who are often away from home or love to travel.

For this reason, we have decided to create a guide that can help you choose the best existing power banks that we will report below.

Before continuing and leaving you to our selection, it is good to answer a question that you often ask: ” how many times can I recharge my smartphone with a power bank? “. The power banks’ capacity is expressed in mAh: it is mistakenly thought that the package’s capacity or the device is the actual one.

To obtain a more or less truthful estimate, it is necessary to multiply the indicated number by a multiplication factor less than 1 resize it. Usually, this fluctuates between 0.7 and 0.85 in the best cases. Thus, for example, a 10,000 mAh power bank effectively ranges between 7,000 mAh and 8,500 mAh.

Best Power Bank: Which one to choose

Many people may want to use a USB power bank or external battery pack, but the real question is which power bank to choose? Commuters, who often use public transportation, may only need a small battery to give their phones a boost at the end of the day, while people who travel a lot may need to power more devices across long flights and airport stops. Rather than always having to track down a wall outlet wherever you go, a USB power bank provides a portable emergency power supply for any occasion.

There are various types of Power Banks and also various brands that produce them. Something about the size of a wallet is great to always have on hand for those unexpected (but critical) moments when the phone is dying, and there are no other recharging options.

But if you are looking for something more capacious, perhaps for weekend trips or a regular commute, the slightly larger power banks can easily fit into laptop bags, backpacks, or large pockets and sometimes even offer two or more full refills for most smartphones.

And of course, you can also use them to charge other devices such as tablets, BlueTooth headphones, electronic cigarettes, digital cameras, and much more. Below you will find the best models and the best Power Bank brands that exist.
