I like to have a certain tire pressure every time i go for a session and i am not a fan of hand pumping.I also have a hard time finding a good compressor pump even in gas stations,they are either weak or show incorrect readings.Plus they got tired of seeing me hijack their pumps every other day.So i stumbled across this device,a small wireless compressor pump from Xiaomi,the Xiaomi Mi Portable Electric Air Compressorhttps://www.youtube.com/watch?v=hFJ7Xv0goCEI thought there is no way it can provide the advertised 150 psi or it would probably just take ages to reach enough pressure.I am so glad i was so wrong!This thing became my favorite bike tool!It is more powerful than a lot of gas station's compressors in the psi it can reach,very accurate on psi/bar readings immediately when you connect the valve,very fast on pumping,one charge lasts for many many re-fills,even has a built in flashlight so you can pump at night,it keeps your desired psi pressure as a preset and remembers it next time you press start,so you only have to press a button,it automatically stops when it reaches the desired psi,you don't get air loss on connecting/disconnecting the valve,deflate option,plus the quality of construction is outstanding.Also the price is unbelievable,around 30 euros.The joy of having your exact desired pressure before every session without pumping or going to the gas station is something i didn't know i needed!Check this thing out! (This is not an ad!I just wanted to share something that made my life a bit easier and earned me some time too!)
Can you please measure how much time it takes to reach 150psi?
Mine arrived yesterday. It's so simple to use and seems well built. The reason I got one is so that I can quickly get my tires to the same pressure easily before each session. It only takes a few seconds per tire to replace the air that is naturally lost between sessions.
