Pros and cons

Pros

Battery operation offers cordless use, while 12V DC power provides an alternative for longer sessions.
Automatic shut-off at a preset pressure can reduce the need to monitor inflation continuously.
The stated 150 psi maximum and compatibility claims cover car and SUV tires, motorcycles, bicycles, e-bikes and sports balls.

Cons

Cordless use is limited by the claimed runtime of up to 18 minutes, so extended operation depends on 12V DC power.
The listing says the unit is not suitable for trucks or large industrial tires.

What to know before buying

The stated inflation times, pressure accuracy, durability and runtimes are manufacturer claims, not independently verified performance. The listing says pressure variance of ±1-2 PSI is within normal tolerance.

Listing details to confirm

Use intermittently. The listing advises against more than 60 minutes of continuous operation and says to let the unit cool for 40 minutes before resuming. The 18-minute cordless and 60-minute 12V DC runtime claims apply to different power modes. The stated 18-minute battery charge time is not clearly reconciled with runtime, so confirm charging expectations before purchase. The listing describes a rechargeable battery and 12V DC dual power, while the technical details list only Battery Powered and a 12-volt specification. The 35 liters capacity is not explained in context. Confirm the selected listing's power configuration and capacity meaning if these details matter.
