False Advertising
Advertised at 30.8ah (30800mAh). Amazon ad stated this equates to 99.2 watt-hours, which would mean this is a 3.22 volt cell, or a LiFePo4 battery, which is incorrect. However the actual battery has "30800mah and 113.96 wH" printed on it, which makes more sense for a Lipo battery (3.7volts)....I ran a capacity test at 5volts/2 amps load. It produced only 53 watt hours. This all makes sense because it's weight is about half of what all other 30,000mah battery banks weigh.. This is a complete farce and nothing but false advertising. It will be returned for a real 30,000mah bank. And yes I realize I could have tested it with only a 1 amp load, but that is not a real world scenario as the ports are rated at 5volts/2.1amps, nor would it have made that much of a difference in watt hour production. This manufacturer's claim that these cells are somehow magical since they state they are "high"capacity" cells because they only weigh half as much as others is total crap - maybe it's a 21000 if you take in to account the loss due to conversion from 3.7 to 5.1 volts.
