made this purchase because there were good reviews on YouTube, I needed a power station for air mattresses, usb powered fan and charging 2 cellphones, I was able to fill 6 twin air mattress that were 20inch tall that uses a normal house plug, even topped off through my 5 day camping trip. It used 1 percent per mattress. Cellphones were always charged and usb every night for a few hours, at the end of the trip I'm left with 60 percent power left.
If this accurate, this powerstation is totally awesome.
