why don,t you test it ?


its rated at 7800mAh , which is 7.8 amps @ 5v , therefor a device that uses 1 amp would last continually for 7.8 hrs


if that was 7.8ah , I think tesla (cars) would have placed a bulk order for them by now


having tried one as an emergency power supply to feed the side/tail light on my 6v , 30 yr old trials bike , I estimate there true output to be less than 3000ma

save a fiver, similar rated at 5800mAh on ebay for £5 delivered... mine is pretty close to the stated capacity

The capacity of a battery in mAh is very carefully calculated... using all sorts of expensive equipment in a laboratory. Unfortunately, one individual piece of equipment is always used... a random number generator.
