Product guide

AstroAI Airun C4 Cordless Tire Inflator, 150 psi

AstroAI Airun C4 is a cordless, battery-powered tire inflator with a listed maximum pressure of 150 psi. Its digital pressure display, preset pressure control and automatic shutoff suit portable top-ups, while the listing’s inflation-time and battery-capacity figures are manufacturer claims rather than independently verified results.

At a glance

The listing describes a digital screen showing real-time pressure, with four selectable pressure units and preset pressure controls.
Automatic shutoff is intended to stop inflation at the selected pressure.
A built-in LED light and a quick-connect hose are described in the feature claims.
The manufacturer claims inflation of a 195/65 R15 car tire from 30-36PSI in 1.5 min and a motorcycle tyre from 29-35PSI in 1 min.

Pros

Cordless operation and a compact, portable design are suited to keeping an inflator available for roadside top-ups.
Preset pressure control, real-time pressure display and automatic shutoff reduce the need to watch the gauge continuously.

Cons

Battery life may limit usefulness for repeated inflation away from a charging source, and customer feedback is mixed on battery life.

What to know before buying

Listing performance figures are claims, not independently verified results. The stated rates apply to the specific car- and motorcycle-tyre pressure increases given, and battery capacity is described without a charging-time or runtime specification.

Listing details to confirm

The listing gives no charging time or battery capacity, so recharge planning and expected runtime are unclear.
