Massive Storage Capacity
This battery recharges my devices many more times than my other charger and it still fits into my pocket or a small bag. The digital display indicating the battery level is convenient. Sleek design so I am happy to display it on a table or car console. Since purchasing I've had no worries about charging my tablet and phone devices.

Massive Recharge Capacity
This battery recharges my devices many more times than my other battery charger and it is not much bigger and still fits into my pocket or a small bag. The digital display gauge is convenient as it indicates how much charge is still in the battery. Good sleek design so are happy to display it on a table or car console. Due to its large capacity I've had no worries about charging up my phone and tablet devices.
