No complaints, ideal to recharge my netbook and other devices by USB or DC .. I have a little MP4 player, I can only watch 4 hours of video with the XT I can reach 40 hours from now! 12% used to charge my Galaxy Note, which allows me to recharge 8x. Strong point: the XT recharges in less than almost 1:30. The connectivity provided is full, nothing is missing. A manual can disappointing in allemeand, but it is not useful to use the battery, nothing complicated. Stops at the end of load detected as soon as a source is connected / disconnected. May seem expensive but it is very effective! I am fully satisfied! thank you!
