I've searched a lot at Revain for a portable rechargeable air compressor and this seemed to be the only one without terrible reviews. It looks like there are good reasons for this. This kid is really strong. It appears to be a well built, beautifully finished compressor. I've only been using it for a few weeks and have used it a few times with no problems. Time will tell about the durability. The device is very convenient to use. Press and hold the power button for a few seconds and the easy-to-read, backlit digital display will light up. Press the plus button and the last set pressure appears. If you need more or less pressure, simply press the plus or minus buttons until you reach your desired set air pressure. Connect the air supply hose and press the power button again and the device will pump until it reaches the desired pressure and then stop. Disable it and within a minute or two the device will turn itself off. The battery makes a pretty solid impression. I inflated four fat e-bike tires and inflated two mountain bike tires from almost flat to 40psi and the battery gauge still showed 3 out of 4 bars. Light up the valve stem when inflating.2 - The battery works as a power bank - It has a USB-A port for charging devices3 - It charges with a USB-C port - Very handy ball pin and inflatable transformer toy. This is the only block I found with it. Very handy so you don't lose these things. 5 - Nice little storage bag to protect the device and store the hose. has a large battery, that's to be expected, and the wrist strap is too small, but I probably won't be using it anyway. It's more like a lanyard on a finger. Overall I think this is the best device for the money that Revain has.
