Bike Electric Air Pump: 150Psi Portable Bicycle Tire Pump with Digital Pressure Gauge for Road Bike, Mountain Bike, E-Bike, Motorcycle with Presta, Schrader, Dunlop Valve Accessories

Bought this pump in September 2024 and it worked good for about a dozen or so pumps and got the bike back out this spring and it pumped fine once and then it still pumps but the connector hose to the pump leaks air so it drops pressure faster than it inflates. There is no customer support available that I could find. Can't recommend anyone buy this pump due to lack of support and obvious quality problem.

Just exactly as described

This pump works pretty well, but before you buy it, there are a few things to consider if you're thinking this would be a good substitute for a good floor pump (the kind that works on muscle power): (1) this pump is noisy; (2) it takes a while to pump a tire up fully; (3) It needs to be fully charged if you want to pump a tire up completely. I have presta valves, and the connector works well for that, but it's not obvious how to use it (the directions do explain the proper use). It is important to tighten the hose on to the valve as tightly as you can to avoid leaks (my hand pump connects much faster and more conveniently). Be sure your tire is rotated so that the valve is at floor level so that the pump can rest on the floor, not hang from its hose. You can carry this pump on your rides if you like, but for regular road biking, it's relatively heavy (348 ounces, about 3/4 of a pound). However, in case of a flat you could at least get your bike's tire back to its regular pressure, which is hard to do with the kind of hand pumps that riders with road bikes commonly use. And it would be a LOT less work than using one of those small hand pumps that you carry with you. If you are trying to put a large volume of air in your tires (as you might for an e-bike or a mountain bike when the tire is completely flat), I suspect that you may not be able to run it long enough to completely do the job without having to recharge the battery. I used it to completely inflate a tire on my gravel bike (starting from the tire having no air), and it was just barely able to get it to 65 pounds before needing a recharge. (My tires are 700 x 32 mm.)

Actually works very well and is super convenient.

Junk. Does not always work correctly. Set it to 50lbs tire pressure on a tire that only had 5 lb in it and it reads that the tire is at 50lbs and shuts off. Wish I knew it had this issue but by the time a had to rely on it 30 days had gone by and tuff luck. A real POS.

I had no trouble understanding the directions and using the pump. It's nice to see the starting pressure when you attach the hose to a valve, and that confirms it's attached fully. I used it to top off four bike tires. For one of them, I did not get the initial pressure. There is a part you turn to switch between Schrader and Presta valves which I had inadvertently loosened. That caused the hose to not fully engage the Schrader valve. Once I tightened that part, it worked perfectly.The pump should be easy to pack into a repair kit to carry on our longer rides.

Arrived same day which is above and beyond. Only used once, but electric pump seems great and exactly what I was looking for. Very easy to use. Pump screws on to valve and pumps air like a compressor which technically it is so no more of that valve pressure when releasing hand pump. I was always afraid I would rip the valve when pulling off. Pump shits off automatically and psi is much more accurate than hand/foot pump- I checked pressure with a separate pressure reader device. I only used once so I cannot comment on longevity of electric pump, but so far so great. Recommended for sure.

Fantastic pump. My son loves it so much for his sports activities, that I have to buy another one for myself. Accurate air pressure.
