Mobility seems to be the big focus these days. We spend a lot of time with a smartphone or tablet in our hands and it seems that none of the manufacturers got the message. We need bigger batteries. A smartphone barely survives a day of regular usage. The same thing goes for tablets. we get bigger screens, more powerful hardware but the battery technology stays the same. This is why we now have the infamous power banks.

When power banks were introduced, not many people took their utility seriously. As it turns out, power banks are almost a necessary accessory. They serve a very simple purpose. Power banks can charge smartphones and tablets several times. This proves to be very useful for people traveling or any individual that simply does not have access to a wall plug to charge their phone. Most of these power banks are made with 18650 battery cells which are also used in laptop batteries. They have high capacity and they are quite safe. The capacity of these power banks can vary a bit but it is worth noting that power banks with a capacity below 5000 mAh are not very efficient and will barely charge a smartphone 2 times at best. For this reason, for our list, we only included power banks of at least 5000 mAh.

What To Look For When Searching For Power Banks?

There are literally thousands of different power banks on the market. This is because they are quite easy to manufacture. Sadly, there are a lot of manufacturers that use bad rechargeable cells, lie about the capacity or have very poor quality control which is why making a top 10 list has been quite difficult. Here are some of the things worth watching out for.

USB port numbers. Usually, power banks that have a capacity lower than 10000 mAh tend to have just one USB port. Larger power banks have multiple USB ports which means they can charge multiple devices at the same time.
Capacity. The capacity of the power bank determines how many times it can charge a smartphone. Ideally the larger, the better but this also makes the power bank larger and heavier.
