LILTSDRAE Bike Pump Mini Tire Inflator Portable Air Compressor 150PSI Cordless Electric Bicycle Air Pump, Auto Shut-Off with Presta and Schrader Valve Smart Electric Pump

Its a little larger than I expected (sorta like a white claw can but a little shorter. And it has a decent heft to it. It certainly feels solid. The noise when pumping is less than your typical 12 volt portable pump. I love the utility of the auto shut-off. The speed of inflation is much better than I expected from a battery powered compressor. Its not amazing or anything, mind you but its decent. Battery life: I charged it to full and inflated four 20x1.75 bike tires from around 8 PSI up to 50 PSI each. After that I was at 3 out of 4 bars on the battery meter.

Never underestimate small things. I was speculating whether this thing would work or not. The best money I ever spent all for my tires are low between four and 8 pounds this thing filled up all four tires 38 psi in no time did not use one bar on battery life. I recommend this device For everyone.

I purchased this for my husband, he rides daily. If he gets a flat on the road or mountain, he can add the air in which he needs in minutes.

I purchased this for my bike tires requiring 100 psi. It does work fill them multiple time before charging. It does take more time than I had thought to fill them up but most likely any compatible inflator would by design. It is nice for a quick top off. The only negative review is using it with the Presta valve. It does fit with the adapter but needs some work to get it to fit without leak. Fits easy on a Schrader valve.

This thing is AWESOME !!!! quiet/ quick/ fits in pocket.....love it Filled my bike tire in 30 seconds...

This air pump saved the day. I often ride road bikes with a large group. In one night I was able to fill 4 tires and get my friend back on the road way faster then a hand pump. Everyone was super impressed by how fast it worked. I dont know why I didnt buy this sooner! Amazing

I bought this product to put air in my bicycles tires. Unfortunately, it refuses to inflate past 35 PSI. These tires can take 60 PSI, but it simply will not pump that much air. It appears to work properly; it just stops at about 33-35 PSI. In fact, when it hits its limit, the PSI number starts going backwards. Thinking perhaps the first tires value might be defective, I tried it on the other tire, but got the same results. It seems unlikely that BOTH values are defective, especially since the bike is almost brand new. In any case, I tried leaving the pump running on each tire until the battery ran out, and it still would not inflate past 35 PSI. I havent been able to find a website for the company that makes and sells this product (so I could seek help from its customer service department). I hate writing a negative review until Ive given the company a chance to make things right, but it seems my only option is to leave this review in the hope that someone from the company will reach out to me to help resolve this problem. If they do, I will change my rating.

Definitely worth the buy. I just bought a bike and didn’t know how much air it needed. Turns out bike came to me well deflated. Only at 20psi. The bike needed 60psi. When I sat on it prior to airing up tires with this handy gadget, the tires looked flat. I charged this up, connected it to tire, the settings were easy to change. Bike tires to me seem hard. But it’s exactly what the tires needed. I would’ve tried riding this bike with low tires, if I didn’t buy this. Testing how much air is needed with hands and a squeeze isn’t the proper way. Don’t be fooled as I was. YOU NEED THIS.
