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

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.

Got this last minute because my last mini pump broke. Never had an electric one before. This thing takes almost zero time to use, and can pump a bike tire from 2 bar to 8 bar while using less than half its charge. It’s super portable too. Comes in a little carrying bag, which is good for not losing the little adapters.

Great product and price. Perfect size for packing or carrying. Easy to use and well made.

Well made. Operates as advertised. Nice little unit.

Good price and good benefit

Ningún problema para usar y es pequeño

Only used it twice so far. Easy to use fairly accurate would be better with a longer filler hose but its been good so far. My previous ones, different manufacturers, didnt make 14 Months with an average of Three uses. Im hoping this one does better I only use them for my bike tires

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

Well designed pump. Liked the pre-programmed setting for bicycle & auto tires & the compact size. Worked well to increase road bicycle tire pressure to 85psi a couple of times & to increase pressure in 17 minivan tires by a few pounds. Didnt use for several weeks; then a minivan tire needed air. Could not use at all - even with the battery fully charged, it ran for only 1-2 seconds and then shut down (repeatedly). I then tried it with a bicycle tire and got the same result! Amazon description says 1 year warranty but provides no help with contacting the seller. Thankfully I purchased an extended warranty so I now have to file a claim. :-( UPDATE: I did not have to file a claim - the seller saw my review and voluntarily issued a full credit. Changed rating from 1 star to 3 stars (1 star for the product that failed; 5 stars for the sellers handling of the situation!)

Works great, super light. Hard to read in daylight due to setting dimness, but overall good tool.
