Overview
This Carsun digital air compressor is a corded 12V tire inflator that plugs into a car's power outlet, rated to 150 PSI with a digital pressure display, auto shutoff and a 10-foot power cord. It suits drivers who want a plug-in pump kept in the trunk rather than a battery-powered unit to charge.
Because it draws power straight from the vehicle's 12V outlet rather than an internal battery, there is no charge to run down before you need it, at the cost of needing the car running or the outlet powered. The 10-foot cord and four extra nozzle adapters extend its reach and use beyond car tires to bikes, ATVs, air mattresses and inflatable boats, though the manufacturer excludes trucks and lorries.
- 150 PSI max pressure, 35L/min airflow
- Inflates a 195/65R15 tire from empty in under 5 minutes
- 10-foot cord with 4 additional nozzle adapters
- Digital pressure gauge with preset auto shutoff
Who it's for
Fits drivers who want a simple always-ready plug-in inflator for a car, bike, ATV or inflatables, and don't mind running a cord to the outlet. Not sized for trucks or heavier commercial tires, which the manufacturer excludes outright.
Strengths and trade-offs
Drawn from this product's published specifications.
- Digital display with a preset auto shutoff
- 10-foot power cord plus 4 extra nozzle adapters
- LED light for use in low light
- Powered from the 12V outlet, no battery to charge
- Corded design needs the vehicle's power outlet running
- Manufacturer excludes trucks and lorries
Performance notes
Set the target pressure on the digital display first and the pump shuts itself off once the tire reaches it, so there is no need to watch a gauge while it runs. At a rated 35L/min airflow and 150 PSI maximum, the manufacturer states it can bring a 195/65R15 tire from empty to 35 PSI in under 5 minutes, drawing power the whole time from the vehicle's 12V outlet through the 10-foot cord.
