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

I needed to inflate some seriously deflated bike tires and my mini pump wasn’t going to cut it. I ordered this pump, figuring I could also keep it for my car tires. It works really well, inflates quickly, and is fairly intuitive to use. The display is very helpful to know how much air you’ve added or need to add, and at what pressure. Highly recommend!

This thing is AWESOME !!!! quiet/ quick/ fits in pocket.....love it Filled my bike tire in 30 seconds...

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.

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.

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 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.

Great for hefty e-bike tire. Exact psi

i like this product, is always a reliable and quick to inflate tires. I was expecting something with less weight so easy to maneuver it. Overall im satisfied, but will i purchase this again.... probably not

Using this in my bike bag. The times I have used it it has worked very well except that the display cannot be seen in the daylight. I had to remove it from the tire and enter the settings in my car, and even then the display is kind of hard to see.

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.
