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

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 have a large air compressor, but I thought this might be nice to have for inflating various sports balls. I needed to top off my motorcycle tires and thought I would put this little guy to the test. Being honest… between the brandname, the price, and the size my expectations were really low. Certainly it would struggle, the battery would die quickly, and maybe there was a real chance it would overheat and die. Cannot say I was disappointed. In fact, I was surprised at how well it did. It seems well made; no rattles or weird noises. The battery added 10 lbs to each tire to 40lbs. It took about 3 to 4 minutes for each tire and the battery gauge still showed 4 of 4 bars. No regrets.

Though I am in a wheelchair I lead a very active lifestyle and have aggresive tires on my chairs. I have always wanted a reasonably priced, compact, rechargable air compressor with some power to it for traveling. This really seems to fit the bill. As soon as I got it, I put it on the charger till fully charged. Then I went to test it. This pump filled my 26x2 inch wheelchair tires from 18 lbs to 37.5lbs in less than 30 seconds. Did the same for my other chair. Total of 4 wheels. Then the real test was 90lbs on my 4X4 truck bed which took little over 3.5 minutes to go from zero to 90lbs. After that I hooked it up to a couple of regular 26x1&3/8 chair tires that were totally flat and it took about two minutes for each tire. Finally I went out where my SUV had a low tire. It went from 21psi to 32psi in about 3.5 minutes. ALL THESE WHEELS ON ONE CHARGE. Be warned though, it gets HOT after 3 minutes so you need to let it cool down between those longer lasting jobs. Also, to turn the light on, use the bottom button (M) to activate the light icon then hold down on the top (U) to turn it on. See pictures. The directions are very scetchy on how to go this. Overall this brand of compressor air pump is a great value for the buck. Reliable, powerful and compact.

I bought this for my bicycle that has a really slow leak in the front tire and this air pump works great, its not to loud light weight and easy 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 purchased this for my husband, he rides daily. If he gets a flat on the road or mountain, he can add the air in which he needs in minutes.

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

Great for hefty e-bike tire. Exact psi
