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

Nice little portable USB powered pump for bikes. I like the size and works well. I pumped 4 road bike tires to 70psi each with no issues. Only used up 2/5 bars on battery with full charge. It even comes with a nice presta valve adapter. 2 Complaints 1) Pump barrel/tube attachment gets really hot (let it rest after pumping 2 tires) 2. Heavy & Size. It comes in the size of a soda can except narrower. Too small to fit in bottle cage yet cant fit in back pocket and pretty heavy. Very inconvenient size. Everything else about this device is good. Most important thing is it works but doesnt help if you cant take it with you.

Small but lots of power.

Works perfect. Fairly easy to use. Takes a second to understand the air setup and different application choices, but once that’s done works great. Only problem was with the button on top for the light… kept trying to press it to turn on the light and the button sunk into the body of the pump. So, the light doesn’t work, but great for pumping up bike tires.

Just flat out I didn’t like much about it , I’m sure it works fine but it didn’t meet my expectations!

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.

havent used it on a car yet - but it wouldnt blow up party baloons

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.

Compact and easily portable. Easy to use except for the short threaded hose connection. The hose is short to allow storage within the unit, however the short length makes it difficult to attach to the tire due to having to thread the hose on the valve stem. A right angle connection would make it much easier.

I have a recumbent trike with 100 psi Schwalbe Marathon tires. I just couldnt get the tire anywhere near full pressure even with a nice hand pump after fixing a flat out on the trail. This takes it all the way up quickly, does not take much space in my trunk bag. I just have to remember to fully charge it before long rides. Ive been able to help out a couple other people out on the trail, they all ask, where did you get that?.

Charges as it should looks like it would be fine. As soon as I pump up my bicycle tires I will let you know if it really works
