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

Overall, I would give this gadget a 5-star review, but I am finding it less than simple to learn how to use it. The little instruction leaflet is not much help in general. The device has an LED light that i still havent figured out how to turn on and off. Im not much when it comes to being technically inclined, but it seems to me that printed instructions could have been easily written to be much more helpful than this one is. Eventually, Ill figure this thing out and it will become the best thing ever for inflating bike tires, etc. For now, however, Im still floundering . . .

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

after fiddling with all the settings to get set correctly it was great! set my 85 lbs of pressure for a tore, screw it on, and press the button. Working on the pressure is reached, very simple.

I had bought a simple pump for my bicycle, but ut just was too much time getting the air in my tires. Bought this and follwed instructions. It was charged a little, but I charged it fully. Works wonderful.

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

It died after 4 months and only occasional use. Update; The seller has refunded my payment and Im happy with that result. Good Seller.

I just received this product today, so I cannot speak to its durability. However, within minutes I had two road bike tires automatically inflated to my selected pressure (80 PSI). This is far, far easier than using a floor pump or, worse, a hand pump. Do be aware that this product is a little heavier than you might expect and would be cumbersome on a bike unless you have a good frame pack. Im going to throw it in my backpack when I commute by bicycle and in my trunk whenever Im in my car. I will keep the small hand pump I have mounted to my bicycle for low-tech backup. I think this product is great value for money. Its only twice as expensive as a basic floor pump, yet so much faster and easier to use.

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.

My son is able to carry this easily in case of an emergency while biking.

It has many settings with A LED light that did not work. It comes with a short type-c charging cord with no wall unit, while charging the unit can not be used. It has indicator when it is done charging in 5 steps. It has five modes from tire down to a ball mode which I used. The range of 0 to 15 psi. I set it for 5 psi and it stops the compressor at that setting. This was for my reverse osmosis 3 gallon holding thank with a tire fitting on the tank bottom that needs between 5-7 psi of air to work the filtered water out of the holding tank.
