Anker PowerCore Power Bank

You've probably heard about Anker, and it's one of the best portable chargers in the business. It comes with a huge 20,100mAh battery inside, which means it can charge your phone or tablet a few times before needing to be recharged.

It also comes with a high-speed charge for your devices if they use PowerIQ or VoltageBoost. It will not be able to use Qualcomm's QuickCharge technology, but it will still increase your device when you're on the move.

AUKEY Power Bank

If the Anker is not good for you, our next choice is the Aukey 20,000mAh battery. It has two ports so you can charge your phone and tablet at the same time and also has a light to show you how much the battery is charged.

The block design may not be for everyone, but this portable charger should be able to charge your phone and other gadgets several times with such a high capacity cell inside. In addition, the price of Aukey battery has dropped for Black Friday 2017, so you can only get it for two-thirds of its usual selling price.
