🔌 Chamvis USB Rechargeable Electric Air Pump for Air Mattress, Boats, Pool, Exercise Ball - Portable Inflator/Deflator Pump with Nozzles - Battery Powered Review

The pump is easy to use, light weight and has more than enough power to inflate paddling pools and air mattresses. If the power cords were a little longer, maybe a foot, maybe two feet longer, this would be the PERFECT air pump. I would recommend it.

This is a great idea, but it doesn't have enough power to inflate an exercise ball. He kept running but couldn't use the ball to the point where it could be used. It was fully charged, tried to connect, tried every way it could but it didn't work. It's such a pathetic waste of money.

This little guy is a powerhouse! I used it to inflate my 14 foot river raft. Full disclosure, it doesn't have enough force to open the valve with airflow, but that's not surprising given its small size, so all you have to do is open the valve to inflate and close. Even better, you can use it to deflate the boat at the end of the ride, making driving that much easier! It was fully charged to begin with and I inflated/deflated it and it only dropped 1 bar. I love the USB charging port, I could…

I ordered this specifically to inflate my very old exercise ball. The valve closest to this one wasn't perfect, although I got it to work. I want to reiterate that this valved thing will probably work better on NEW style practice balls. Mine is quite old, maybe that's one of the problems. The other problem, however, is that the way it's made is pretty flimsy. When a person fills the ball himself (like in my case) it's very inconvenient and a couple of times I've used it the little thing came up
