Does it work?

------------------

Glad to say, yes. it charged my Google Nexus 5 from absolutely flat to 100% in around

90 minutes.

The battery is rated at a 4,000 mAh (the higher the bigger the capacity) which means

it should charge a smartphone several times before finally needing to be plugged in.

For example, here's the battery capacity (mAh) of some of the more popular

smartphones:-

* Google Nexus 5 - 2,300 mAh - Recharge 1.7 times

* Samsung Galaxy S3 - 2,100 mAh - Recharge 1.9 times

* Samsung Galaxy S4 - 2,600 mAh - Recharge 1.5 times

* Apple iPhone 5 - 1,400 mAh - Recharge 2.9 times

* Apple iPhone 5S - 1,570 mAh - Recharge 2.5 times

* Apple iPhone 6 - 1,810 mAh - Recharge 2 times

* Apple iPhone 6 Plus (Phablet) - 2,916 mAh - Recharge 1.4 times

Each of the above are estimates (you never quite get 100% efficiency out of a

battery), but they’re a good estimate.
