Your specs mention voltage and amperage capabilities, but specs are missing telling us how LONG it will be able to hold up it's output. "5v at 1000ma" is all well and good, but will that output level last for five minutes, or five hours?


According to the manufacturers the PowerGorilla is rated at 20,000mAhrs at 5V (100Whrs) so I would expect the USB at 5V for 1000mA to hold up for around 20hrs. I would expect it at a minumum for at least 15hrs. Again this will depend on a lot of factors such as the temperature and age of the battery as Eugene has indicated. Typically the Lithium Polymer will lose 20% capacity/year at 25C. This can be reduced to around 2-5%/year if the battery is stored in a cool location i,e in the Loft space during winter when not in use and in the Fridge during the summer when not in use.

The PowerGorilla cost me $178 at todays exchange rate or £120.
