You can get basically the same pump, minus the phone charger part, on Amazon for about $35.

Love my aventon electric bike!

I have had the Fanttik X8 Apex air pump for most of a year now and used it to inflate my motorcycle and car tires many times. This little pump is very well made and compact. It can easily and quickly air up any of my tires, and with a capacity of 150 PSI, the tire pressure is never a problem. It charges easily on the cell phone charger and the battery is quite impressive. When I air my tires, I air up all of them at the same time - motorcycle and both cars. Just topping the tires off to the correct pressure only takes about 1/4 or less of the battery capacity, which is conveniently displayed on the pump. Once, I had to air up all the vehicles tires, plus one car tire that was very low and needed a lot of air. The pump handled it all very easily and it still had over half the battery remaining when I was finished. It is super easy to set up the pump to inflate to any pressure you desire, and it automatically stops after reaching the set pressure. And, it even displays the current tire pressure when you connect it to the tire. I checked the accuracy with a tire gauge and the pressure was spot-on accurate. Also, the pump is surprisingly NOT very noisy. It has some extras, like the built-in LED light, preset modes, and USB port for powering other devices like cell phones. In summary, I haven't seen anything I don't like about the X8 and would highly recommend it to anyone who wants a good quality and easy-to-use inflator that you can just pick up, turn on, and air up literally anything with it. And, on another note, I also have the Fanttik electric screwdriver, which is also a very good tool....but that's another review.

This pump Works OK but the file pressure reading on the a leading display is off by seven pounds above the original display. So if the rates 30 pounds of pressure is actually 37.
