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

Good to have

Magical and handy product, easy 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.

I bought this little air pump for my e bike, “ that I park in the house “. I have a compressor in the detached garage but I wanted something more portable. This little pump is perfect! In the description it said it was about as loud as a blender. I must have a loud blender because this is much quieter! Now I only keep the bike wheels topped off to 40 psi, so I was a little concerned about the screw on valve stem so I set the pump to shut at 41 psi. Turns out, it loses very little air unscrewing the hose. The manual is pretty straight forward but the pump is very easy to understand and use. I absolutely give this a five star! If you want something small, portable, quiet and powerful, this will meet your expectations.

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.

Only had this little guy for a short time but works awesome. Only use it for my bike with the presta adapter and it saves me a ton of pumping and hassle. It is surprisingly not a really loud or annoying sounding motor. I carry it right on my bike strapped in a cargo cage. Some people reviewed that they put it in their bottle holder but I dont know what kind of bottle holder they might have because it is too small for a standard bike bottle holder and will fall out unless you have extra straps or wrap it in something.

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.

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

I loved that it was easy to use and very light weight

Great for hefty e-bike tire. Exact psi
