Preset pressure cut-off is the feature, not the maximum bar rating · review
A low-cost cordless inflator with a 19 mm cylinder, a dual LCD, five preset modes including Bicycle, USB-C charging and a power bank function.
Our conclusion A lot of inflator for the money, with less of a track record.
The Oasser is the cheapest electric inflator on this shelf, and it does not look cheap on paper.
A 19 mm cylinder with a 390-type motor, a dual LCD showing preset and live pressure, auto shut-off, five modes including Bicycle, a custom range from 0.2 to 10.3 bar, four pressure units, USB-C charging in around 4 hours, a power bank function, a quick-lock chuck and a three-mode LED light.
The Xiaomi on this shelf also claims a 19 mm cylinder and 150 psi, at about three times the price. The AstroAI L7 has a far longer record on Amazon.com. What you give up here is mainly history. A quick-lock chuck that needs no twisting is a good feature on a low-priced unit.
The listing talks mostly about car tires. For Presta valves, make sure the adapter is in the box, or plan to buy one for a few dollars. Keep the unit charged, as a lithium battery that sits empty all winter is what kills cheap inflators.
