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

This compact rechargeable tire pump is excellent. I bought it to use with bicycles including my new electric-assisted bike with 16 inch wheels, and older bikes with 20 inch wheels. The pump charges with a USB-C cable. It arrived fully charged. After inflating two older bikes from 0 to 55 psi, and the new bike from 30 - 55 psi, 3/4 of a full charge remained. The air connector sealed easily and completely, and disconnected with no loss of air. The unit measures only 5 x 3 x 2 inches. It is fairly quiet in operation. It comes with several connectors including a needle for basketballs etc, The instructions are clear. It displays the starting pressure when you connect it, and shuts off automatically when it reaches your set pressure. You can set to PSI, Bar, kPa, or kg/cm². I picked this brand because I also own an AstroAI electronics test meter that I like quite well.

I purchased this to air the tires on my car. It works great. I checked all four tires and added air. Then I aired a sports ball and an inflatable. I had no problems and hardly used any of the charge. It is a handy item to have around the house and it is very reasonable priced.

This portable air compressor works like a charm and is almost perfect. The only issue is the screw-on tire valve connector—it’s tricky to get a solid seal, and not something you want to wrestle with in the dark. I couldn’t even manage it easily in broad daylight.The fix is simple: I bought a locking air tire chuck that screws onto the pump’s hose and converts it to a clip-on style. It holds the seal reliably and makes the whole process much easier. These are inexpensive, and I’d call it essential if you plan to inflate car tires. Save yourself the hassle and order the chuck at the same time.

I have a girlfriend that is not that great when it comes vehicle maintenance. She forgets to change the oil and essentially just turns up the radio if the car makes a noise. I work out of town a lot so I cannot always be around to assist with certain maintenance activities. Somehow, her car attracts nails to the tires quite frequently. She is afraid to use the air compressor at the house, and I needed a way to ensure she could safely get her tires aired up to take to a shop.This little compressor works wonders. It is quiet, compact, and easy to use. All you do is set the pressure to your desired level, and hit the on button. I was highly impressed with this unit for the price. I have some big name brand ones (in the color red) that cost 5x what this one does and it works exactly the same. I will be purchasing another for my mom and sister to keep in their cars!

This little inflator device is amazing. Not much bigger than a soda can but can inflate a car tire in less than 2 minutes. It has a great display letting you select what kind of job you have; car, motorcycle, bicycle, basketball or custom and then set your desired pressure. The inflator stops when it has reached the set pressure. It also has a LED flashlight and a red LED warning light that can flash. Very easy to use and move through the menu. You can also use it as a battery bank. This is my third purchase of an ASTROAI device; this inflator (2), a multifunction jumpstarter, and a multimeter (2). All of the ASTROAI devices I have are well made, durable and very easy to use. I would give this inflator 6 stars if that was an option.
