TERRIBLE POOR BATTERY LIFE
I would not recommend this charger to anyone. It's giant and the power supply lasts an hour or so. At first it worked well but it quickly failed. There are many better power adapters out there. I now use an Duracell small charger which fits in my pocket and I'm very happy with its power life.
First one, out of the box, does not work. returned it. Second one worked twice, then completely died out for no reason. I returned the second one for a refund. I was really disappointed. 13,000 mAh!!!!! I really looked forward to use this device for years to come, but I guess if it is too good to be true then it is too good to be true.
Fail. Bought it to recharge my smartphone when geocaching. I didn't need it for a couple of months but made sure it had a charge (just in case). Thought that I would finally try it in a controlled environment (at home on an android tablet). After an hour it didn't seem to have any impact on the android's battery. Put the powerflask back on the charger. The powerflask would not recharge. Response from Digital Treasures was we didn't sell it to you. Response from Staples was that it was outside the window for returning electronics.
I found this to be an excellent battery. I use it all the time. It charges my iPhone numerous times. It will even charge an iPad one time. I use it at my desk instead of the wall charger and take it with me when I travel. Saves me when the iPhone battery discharges in 4-5 hours with a lot of internet or email use. Well made, charges easily, and keeps its charge well. Haven't found the LED flash light of much use, but it's there. Fits easily into a coat pocket or into the side-pocket of most cargo style pants. I have a camera vest that I take with me when traveling and it keeps all my items (phone, battery, cords, iPod) all together. There is two outputs, 1 amp and 2.5 amps and both can be used simultaneously.
