We often need extra high capacity, good performing power packs when We are out and about. These external battery juice packs really do a good job if you are going to be away from a power supply for a while.

The EasyAcc Monster 20,000mAh power bank has two charging inputs for extra fast charging and four outputs for you to charge all of your devices. There is a flashlight which is activated by double clicking the button and four power level LED indicators.

It is solidly built, smooth and feels good in the hand and comes with two micro USB cables in the box which is useful. It weighs 16oz (454g). This EasyAcc is definitely one of my favourite juice packs for its multi USB charging capability and reasonable price.
