Seems to work really well - inflated two airbed with no trouble at all. Not tried to charge it off the car battery yet but that's a really useful extra
inflates airbed really quickly
too easy to knock switch and turn on by mistake
The pump have no light when charging. How long do we need to charge the battery?
The pump is a very good idea especially when your out camping
Only used it the once so far; after charging the unit up, it pumped up a double air bed very quickly.
