What you’ll notice day to day

You’ll appreciate the speed and the hands-free behavior thanks to the preset and auto-off functions. According to the manufacturer, the sensor samples pressure at 200 times per second and achieves a higher valid data rate than average, so readings tend to be more consistent. The USB-C input and output let the inflator double as backup power for small electronics while the built-in LED acts as flashlight, SOS or strobe light for nighttime tasks.

How to use it

Start by selecting the appropriate mode and pressure unit, attach the nozzle, and the pump will run until the preset value is reached. It refills a typical 195/65R15 tire from 30 to 36 PSI in about 1.5 minutes, and a full battery can handle multiple tires on a single charge. Keep in mind the device is not compatible with heavy-duty tires, so it is best for everyday cars, bikes, motorcycles and sports equipment.
