It will charge my smart phone very quickly and i can go from zero to full charge three times before recharging the unit

Doesnt need to be recharged frequently have only had to use it once so far but it charged 2 smart phones to 100 charge overnight

There are many times i dont have access to power of any type and i needed a way to charge my phone and other devices at all times

Pros lightweight and fairly small two charging ports easy on method shake and its ready long charging life i was able to get three full cell phone charges out of this in one charge sturdy aluminum case very ruggedcons it is slightly bigger than i had hoped but with that said it was the perfect size for travelthis is a great charging device for the money
