- Tyre Inflator Portable Air Pump 150PSI/10.3BAR DC 12V Air Compressor with LED Light, Tire Pressure Detection, Inflate for Car, Bike, Motorcycle, Ball, Air Mattress, Pool Toys

Quality product. It’s been a month and I have used it only once. I will update a more about after few months.

It’s compact, but doesn’t have an inbuilt battery. You will need a 12 V car socket to operate this. I didn’t read this point before ordering and have a mistake .

Excellent product. Well recommended. (The only reason I didnt give it a review sooner, was that I didnt want it to break down!)

Klappt wunderbar. man stellt den gewünschten Druck ein und startet. Recht simpel. Kabellängen sind ausreichend um an alle 4 Reifen zu kommen. Habe es bisher fürs Auto und Rad genutzt und hat ohne Probleme geklappt :)

I've been happy with the tyre inflator so far ie when used for my motorcycle inflating tyres to 36-42psi. However, I've encountered a problem when inflating my presta valve bicycle tyres which requires 100-120psi. I could not get the UGREEN ET501 to inflate above the preset 65psi max limit. At first I could not find any reference in the user manual on how to change the preset to greater than 65psi. On the box it states the unit is rated to a max pressure of 150psi but I could not get it over 65psi. All the 4 modes ie Ball, Bicycle, Motorcycle and Car have fixed max presets for pressure but in the manual fine print (p4) I found there is a 5th MANUAL mode which has adjustable range to 150psi. See screenshot below. Just tested this on my bicycle and it works fine. The solution to delivering pressure above 65psi eg for bicycles with high pressure tyres is to use "hidden" MANUAL mode. I think it would be helpful if the MANUAL mode was given more prominence in the user manual. I purchased this unit primarily for motorcycle touring where it could be used in conjunction with the motorcycle 12V battery thus avoiding problems with inbuilt lithium batteries. In this application it works well. It's compact, has an excellent legible display and is accurate when compared with my reference analogue gauge at 36-42psi range. It inflated a large rear motorcycle tyre (190/50 R17) from 15 to 30psi in 140 seconds. 30 to 36psi took 55 seconds. This with engine off so battery volts lower. Having discovered the "hidden" manual mode which enables pressure up to 150psi I'm giving this practical device 5 stars. I've only been using it for 5 months so I cannot comment on its longevity.

Pequeña, funcional. Sirve para inflar la llanta, estaba ponchada y me sirvió para llegar al taller. USARLA CON EL AUTO ENCENDIDO.

Works great, feels robust, nice built quality, compact and has a nice design. Does it's job well for it's size.
