Pressure sensor accuracy is +-2PSI, compressor pushes air in chunks(steps), so it can not be extremely precise. It's not a big deal is it 50-52 or 55PSI :) For scooter recommended pressure is 50-55PSI. Subscribe, thanks :)
No, you don't need a valve extension with this pump, it's very comfortable to screw, and unscrew. Unlike manual pumps. Check affiliate links in the video description, and don't forget to subscribe :)
There is an old version in my video. This is the new one: www.mi.com/global/product/xiaomi-portable-electric-air-compressor-1s/ It has a bigger battery, USB-c instead of a USB-micro charge port, and a slightly different display. Subscribe, thanks.
