AstroAI L7 Tire Inflator Portable Air Compressor Cordless Mini Bike Pump with Digital Dual Values Display, 150 PSI Car Tires Air Pump with LED Lights&Pressure Gauge for Auto, Motorcycles, Bikes, Balls

Just received it and used it to inflate my wheelbarrow tire. This item came fully charged and worked beautifully out of the box. I would use it on bikes, basketballs, soccer balls and my wheebarrow mostly. It is simply fantastic to use and very easy with no long cords. I charge it at home and take it into the yard. Versatile to use. I have used it for a day. Cannoot say how long it will last or the battery yet.

This is a physically small, light pump which matches my light duty application. I have a Solterra EV. While all cars need the tire pressure set properly, it is more important on an EV. I need to change the pressure by 2 or 3 pounds at a time on 4 tires to maintain 38psi. The pump performs beautifully. It pumps up to the 38psi I set on the pump and stops right on the button. I verified the pressure with my pressure gauge which agrees with the tire pressure monitor in the car. The pump performs accurately. The 5 button control on the device is implemented quite well making it easy to operate. It only took a minute to figure it out. My only complaint is the hose is too short. All the battery operated pumps I see have a hose that is too short. I purchased a longer hose from Amazon: https://www.amazon.com/dp/B0D2X52HY8?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_2&th=1 The longer hose allows me to stand instead of bend over if I am holding the pump. I can set the pump down on the garage floor even if the schrader valve is at the 12 o’clock position on my 19 inch tires. The hose is quite flexible and easy to use. I understand some rims have tight quarters around the valve. Make sure there is room around the valve for this chuck. Overall, this does what I need and consumes only a small space in my cargo area. Quite pleased.

I don't write reviews often, but this is about the best 20 bucks I ever spent. I bought this to keep in my motorcycle saddlebags for emergency roadside repairs. I didn't realize it had a flashlight in it and also a red flashing light which will be good if I'm ever stranded on the side of the road at night. It shuts itself off when it reaches the desired pressure, which is nice to set it and let it do it's thing since it is a small pump and takes a while. Keep your expectations low, as it is a tiny little unit and takes a long time to air up tires. But for what it is, it's perfect. I used it right out of the box to air up a tractor tire and it took several minutes, but it beats driving my tractor to the shop on a flat. This is an awesome little machine!

Amazing little compressor. Super easy to use and can easily adjust the pressure maximum. The accuracy is fairly spot on and it is easy to carry and throw into a travel bag. Only complaint is that it doesn't hold a super good charge, you can maybe fill up about 2 1/2 tires before having to charge it up again.

I ordered this with low expectations. I needed a bicycle pump and this was cheaper than a quality manual pump. It feels solidly made and works just great! Bicycles, motorcycles and our vehicles. It works great for all of the above. So much more convenient than dragging out the air hose and firing up the compressor. Yea, it takes a minute on a truck tire but the valve stays firmly attached so it’s a hands free automatic operation. We will see how long it lasts next.

This unit replaces a portable air compressor that failed a few weeks ago after 2-3 years of service. I charged it up and went out to the garage to find tires that needed inflation. My wife’s bike’s tires were low at 35psi, needing to be at 65psi. I dialed in the pressure level needed and used the quick connect to attach the inflator to the valve stem. The inflator is about half the size as my old unit and it promptly began inflating the tire at a speed that was almost double the capacity of my old unit. I was impressed! I carry small air inflators on my motorcycle for road repairs. Space is always at a premium and this unit will fit in just nicely. Nice product!

Got this to keep in the car just in case, and it’s actually really useful. Super easy to use — just plug it in, set the pressure, and it does the job. I’ve used it to top off my tires and it works pretty quickly. The digital display is nice and makes it easy to see exactly what you’re doing. It’s not huge, so it’s easy to store in the trunk without taking up much space. Overall a good thing to have, especially for emergencies or quick tire pressure checks.

I've had to use this on tires that were very low, both on cars and on bicycles. It works exactly as you'd expect and absolutely has no trouble handling the much higher pressures of bike tires as well as the much larger volumes of typical car tires. I kind of wish it came with some sort of pouch or something because the box it comes in is the only means to store it with all of its attachments,; Because of how tightly it's all packed in the box, it's a bit of a pain getting it all arranged neatly in the box each time, but that's a minor quibble. If Amazon reviews allowed fractional star earnings, I'd probably rate this more accurately a 3.75 or 3.875. It still has two little flaws. One is the accuracy of its pressure gauge. It always seems to fall just a little short. For example, on my car, recommended cold pressure is 36 psi in front and 39 in the back. I tried pumping to those levels, and everything looked fine. But immediately afterwards, the TPMS sensors would tell me I'm at 35 and 37. Likewise, I like to keep my bike tires at around 42 psi for my commuter bike and around 70 psi for a road bike. After using this little guy, and double checking with a separate gauge, I was getting closer to 40 psi and 67.5 psi respectively. I'm inclined to believe it's a calibration/QC problem and there might be examples that overinflate, too. So while I got one that was overestimating the actual pressure, you might get one that has the opposite issue. Still, close enough that I'm not docking it a full point for this, but a faction of a point. The biggest weakness of this device is really a double-edged sword -- its compactness. The fact that it is compact means that it fits very nicely in the under-trunk storage or even a glovebox in some cars. Problem is that when the device is small, so too is the battery. There's just no escaping this. I had a moment with all 4 tires on my car being on the low side in terms of tire pressure. They were all underinflated by about 6-7 psi below spec and so I just used this pump to get them all up to that target pressure. Even with a full charge, I could not get all 4 tires all the way up to target pressures. I could get the 4th tire about halfway there, but that was where the battery died. That's just a reality you will probably have to live with. Given that it is such a small device, this is basically inevitable, so there's no sense complaining about it, but it is a reality you should be aware of.

It pumps for less than 90seconds after fully charged, tyre went from 21 to 26 psi

Produkt porządny, po pełnym naładowaniu 2 koła średniej wielkości nożna napompować

very impressive

It works realy good i recomend :)

excellent
