I have a ps72 716wh power station from these, brand new. It's advertised as a 30ah capacity. I wanted it to charge my 20ah ebike battery on campsites. I charged my bike battery 20/25% & the capacity of the power bank had gone down to 60% on the display. From rough calculations this indicates the power station is around 15ah capacity maximum. This is a Chinese company some of these companies are renowned for exaggerating information product spec. Needless to say I've sent it back & will never buy anything from them again
