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

This pump works well and is extremely easy to use. Just set your target or press start. Can ask for anything more. I cant wait to see how this works on my car.

I bought this for my bicycle that has a really slow leak in the front tire and this air pump works great, its not to loud light weight and easy to use.

I bought it to use on bicycle tires, and have now also used it on car tires. I really like it. Extremely easy to use. I like that I can easily set the inflation pressure, that it shows the current pressure, it show how the pressure is changing, and it automatically shuts off when it inflates to the set-point pressure. It’s remarkable tiny. It has its own little bag. It effortlessly attaches to the wheel. I’m going to buy another one to keep in my other car.

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.

Hose leak but Amazon replaced… good little item for bicycle tires.

This is a terrific product. I got this pump because I wanted to keep my bike tires properly inflated. Its easy to set up and use. I found I could also save a trip to the dealer whenever my tire pressure pops on. Its sometimes confusing to use. When inflating a tire, it has four directional arrows. Left and right increase and decrease the target pressure (up and down would have been more intuitive). Down switches between targets (car, bike, ball, or other), and up changes the units between PSI and three others I never use. I keep hitting the up arrow when I mean down.

Update: received a full refund from the seller for this error, and making this a 5 star review as he deserves. Battery may be weaker and with less capacity as advertised but this thing works like a monster for our cycling and electric scooter needs. Advertised 4000mAh battery; manual says 2000mAh battery. No lock for valve makes it harder to use.

Great little compact pump. Works very well. Hopefully, it will last a long time!

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.

Ive learned from getting a flat tire on my street motorcycle when I was literally miles away from civilization that it pays to be prepared. Thanks to the plug kit and battery rigged pump I carry in my motorcycles saddle bags; I was able to plug the hole in my tire, reinflate it, and go about my day. Due to my right knee acting up from pedaling motion, I stopped riding bicycles years ago, but recently got an e-bike. Im stoked to be riding a bicycle again and the bikes electric motor helps keep my knee from complaining. This translates to me being able to ride for 20, 30 miles or more with no issues, so I wanted some tools to be prepared. I put a rack on my bike, rigged a bag to it, and keep some tools, a spare tube, tire levers, and a hand pump in that bag. One day, I went to ride the e-bike only to find it had a flat tire. I had the bike in the basement, away from the air compressor so I had to use the hand pump. I inflate my tires to 50 PSI... Doing that with a hand pump was not fun, so I decided to go electric. The pump I keep with my motorcycle has to be rigged to the motorcycles battery for power but isnt feasible for my e-bike. So, I got this. In summary, Im very pleased with this pump. So much so that Ive foregone the pump I kept with my motorcycle, and just transfer this pump between e-bike and motorcycle, depending on which one I ride! The manual is really bad though, and even has misinformation. This pump is quieter, more portable, and more efficient than the pump I kept with my motorcycle! The old pump needed its long wire leads with alligator clips to connect to a 12-volt battery, its painfully loud, and it takes minutes and minutes to just add a few PSI to one of my motorcycles tires. This pump is surprisingly quiet for its size and only needs a minute or two to top off my motorcycles tires and even less time to top off or even fully inflate the e-bikes tires. Its ability to store its air hose within itself and not needing to be connected to an exterior battery makes it very compact. So, you might be thinking Okay, youre gushing about this pump. Why four stars? The second part of the review title is why. Not only is this manual written in horribly broken English, but it also flat-out misguides you. The case in point here is the built in LED. According to the manual, you press the LED itself into the housing to active it. I tinker with electronics as a hobby, so my gut warned me something was off; you dont control a light source that way. I shouldve listened to my gut. I pressed the LED in, and not only would it not work, but it also made the screen start acting weird. Once I got a replacement, I disregarded the manual and figured out how to use this myself. I advise doing that. This pump isnt hard to figure out. The U button toggles the pumps unit of measurement (PSI, BAR, kPa, etc.), the + and - buttons set the pumps target pressure, and the M button toggles the pumps memory of presets, which are denoted by icons: A basketball, a bicycle, an automobile, and a User setting. All of these can be adjusted and so long as the pumps battery isnt fully drained (I dont recommend doing that- this pump has a lithium battery!), the pump will remember what you set each presets target pressure to. So, how do you turn on the light? Simple, hold the U button until the LED turns on. To turn the LED off, again hold the U button until the LED turns off. Its not a flashlight, mind you, but for lighting up a shadowed wheel to see its valve stem, the light works great. As far as accuracy goes, this pump seems to measure AND pump to target pressure pretty accurately as far as I can tell. I just have a cheap electronic tire pressure gauge, and my father loaned me a cheap slide plunger type gauge, and this pump matched them both within a few PSI again in both measure pressure and target pressure. Ive only used the pump to inflate my e-bikes front tire that one time so far, and an occasional top-off to my e-bikes and motorcycles tires. But again, this pump has a high-capacity lithium battery, so I will not be testing how much I can use the pump on one charge because I dont want to ruin the battery from over discharge. I would hope the battery has a BMS with over-discharge protection, but Im not going to assume it does. So again, now that Ive disregarded that sorry excuse of a manual and taught myself how to use this pump correctly, I am very pleased with it. Again, so much so that I just take this pump with me packed in whatever vehicle Im riding, and I leave that noisy old pump I kept with my motorcycle at home! If you need a portable pump for car, bicycle or motorcycle tires and lower pressure items like sports balls, this little pump is awesome. Great as it is, I wouldnt try to use this for SUV/small truck tires, let alone large truck tires though.
