I've had mine for about 7 months now and it works great. It can charge my iPhone 5 from dead to full several times before needing to be recharged. I usually recharge it using the Goal Zero Nomad 7 solar panel. I just set it out in the sun during the day and recharge my iPhone at night. No problems so far. I would definitely recommend this product to anyone looking for a good battery pack for gear that you can charge via USB. I'm planning on getting a second one for my wife. I think that says it all.

I got a good one, at least so far.

This is an interesting "Black Box" product with no Label, or any indication on the device showing the manufacturers name. It looks virtually identical to another brand name product and seems to be very well made. I have used it, and tested it, over the past couple of months with these results:

It charged a 3rd generation iPad from 5% to 67%. It charged a first generation iPad from 5% to 100% with power to spare. Amperage and Voltage from the 2A USB port while charging is comparable to that from the Apple wall charger that comes with the iPad. (Charging from either device seems to peak at about 6 watts)

It runs a USB powered fan (ARCTIC Portable USB-Fan, a truly great little personal fan) for over 35 hours non-stop on one charge.

I used it while camping in warm humid weather to run the fan for 3 nights in a row and then used it to power my iPad 3 starting at a 15% charge level on a flight for 4 hours until it was finally depleted and had charged my iPad to 50%.

I have charged it with the "Instapark" 10 watt USB solar panel from fully depleted to fully charged. This took about 9 hours over a 2 day period with the panel laying flat in full sunlight.

I am very impressed with this little power pack, even though it has no name, and despite the concerns I have that the USB ports may not be beefy enough to support my cool little fan over the long haul. It would not be fair, based on my experience so far, to give this any less than a 5 star rating.

this product was good for the time it lasted. i got it to charge once and it will no longer charge. if i just got a broken one i would love for it to be replaced. i would hate to have spent $60 just so it could stop working after one week.
