Tiny Pump Mini Bike Tire Pump with Gauge, 120PSI Portable Electric Bicycle Air Pump, Auto Stop, Type-C Rechargeable Battery with Presta and Schrader Valve

Incredibly light and small. It works well out of the box thus far. It takes about a minute to pump up a tire and the battery only last long enough for a couple of tire inflations, but it inflates faster than a minipump and it is about as light as a couple of CO2s with the pump head. It gets a little warm pumping up a couple of tires, so I hope it lasts.

No issues with this product at all yet.

Happy with product - not happy with delivery time. I ordered over two weeks ago and just came yesterday, You could see that it sat in somebody's warehouse for over a week (Amazon's?) after having been shipped by the seller. So boo on that. As to the product itself - it seems to work as advertised. Fully charged seems to = three "dots" on the screen. I deflated my 32 mm road tires down to under 10 psi, set the pump for 60 psi and used the hose connector to attach to my presta valve (didn't need to use any of the little pieces included, as ready to go for presta). Took less than a minute to pump up to the 60 psi, and then shut off. The charging status showed the third dot blinking, so would assume I've got at least two more charges left. This will be much easier to carry than my current pump, and weighs about the same, so a net improvement in that regard, as well as pumping up way faster and way easier. Biggest risk - multiple flats. Other than that, a great addition to my bike bag.

Small and it pump fast. Battery was great.

I was relatively happy with this pump. I would've given it three stars (four would be generous) until it recently failed. Fully charged, the motor quits after a few moments of running. Got maybe about 10-15 small inflations (never from zero—just topping off tires before riding) before it died.

This was one of the very best micro inflators I've used but I'm probably returning it because of the Schrader valve. It's powerful for the size and was able to inflate nearly 5 MTB 2.5" tires to 20 PSI and fills them up quickly compared to other inflators. Excellent for Presta valves but if you want to use the inflator without the hose for Schrader valves, there is basically no press-fit capability to keep a seal. You have to press hard on the inflator to keep air from leaking out. If you use the hose, then it works, but I don't want to use the hose. For presta, though, you are good to go.

This is an awesome little pump I don’t ride without it now!

I’ve bought 2 portable air pumps previously for carrying on my bicycle but were disappointed on how the battery would be dead when I needed it unless I had charged it right before the ride.This pump is very compact & easily fits into my frame bag or fanny pack. It’s very easy to use and the battery lasts until I need it.I’m pleased with my purchase.
