Personally, this is for ipad and iphones that are energy intensive that I appreciate the battery as it really allows multiple reloads.
I also appreciated the small bag supplied with the battery to be transported easily and different grips provided. I know it's not much, but these are details that I find important.
At the size of the battery, it is a bit the same as an external hard disk 2.5 "with an almost identical weight.
On battery you have 2 outputs:
- 1A Output for iPhone or similar devices.
- Exit 2A for ipad, tablet PC or who need a lot of power.
There was even the battery power button that allows light a lamp to turn your RavPower flashlight if you quickly pressed two times from above :). This is convenient when you use it in the evening outside the house.
The battery is now good for my use and matches my expectations ..
