Pro High charging amperage
The battery has two high power USB ports at 2.4A and 2.1A, which allows most phones to charge at their maximum rate.
Pro Comes with a flashlight
Conveniently there is a flashlight included on the device that will use the built in battery power making for not only a long lasting flashlight that is portable but also a great way to find things in the dark built into a device that is often carried portably.
Con Large size
For what is supposed to be a portable charger the device is not that portable due to its size as it is quite large and may be a pain to tote around.
