This pump holds a charge for ages. It will still take you a while to pump up something really big, even a pool float took longer than I would have liked, but I inflated 5 different things without having to plug it back in for a re-charge. And, it re-charges very quickly.
WORKS SOOOOOO WELL....LOVE THAT IT IS RECHARGABLE....CHARGE IT 4 TEN HOURS BEFORE FIRST USE ....IT BLEW UP MY COLEMAN AIR BED IN UNDER A MINUTE ..NOT KIDDING ....IT IS A GREAT PRODUCT ..AND IT IS SMALL AND COMPACT !!!!!!!!!!!!!!!!!!!!! LOVE IT ......GREAT BUY
This little charger is amazing. I charged it once and it worked for about 8 days blowing up a mattress each day. It's kind of loud, but I think most of these things are. But i definitely love this pump and if you're looking for an inexpensive one that works great, I say get this one.
