Overview
A trunk or garage shelf holds this compact yellow inflator, which runs from vehicle DC power and fills car, motorcycle and bike tires.
Auto shut-off with a digital readout and a light make routine top-ups straightforward. The limitation is the quoted air flow, which points to slow fills on a flat tire.
Who it's for
Drivers who check pressure at the curb and also pump up bike tires will use the small body and LED light. Workshops, off-road users with big tires and anyone sensitive to noise should look elsewhere.
Pros and cons
- Auto shut-off with digital gauge
- LED light for night use
- Fills car, motorcycle and bike tires
- Plastic body in a bright color
- Loud in operation
- Cord and hose lengths ambiguous
- Air flow figure points to slow fills
Performance notes
Fill speed depends on the pump's volume per minute and the size of the tire, so a high pressure rating alone does not mean fast inflation. The auto shut-off compares the digital gauge reading with a preset target and stops the motor. Running from a vehicle's DC supply limits how much power the pump can draw.
