I recently purchased this device to replace my Stitchway iPhone charger and can say that it has been one of the better addons to my phones i have purchased. It has been able to charge my phone from 50% to full in a short amount of time without a dent in the amount of charge the unit holds. I am waiting for my next trip overseas to fully test out the capabilities of this product. I did the recharge of my iphone with no load on the device and it sitting on my desk so my next test will be to run it while videos are playing to see how good it keeps the current charge. The unit is very small and comes with a pouch which can fit the accessories making it great for a trip.
