Smart electric ball pump for sports teams

The ETENWOLF P300 automatically inflates or deflates balls to a preset pressure between 2 and 17 PSI with a precision of ±.3 PSI. Four sport-specific modes cover football, basketball and soccer plus a custom setting, and the last used pressure is remembered after shutdown. A single charge powers multiple inflation cycles via USB-C recharging.

Pressure range and sensor precision define

The pump only operates within the 2 to 17 PSI window, so it cannot serve high-pressure tyres or low-pressure inflatables outside that band. Accuracy is rated at ±.3 PSI, meaning the final pressure may sit slightly above or below the target. Inflation takes roughly one minute per ball, so large batches require sequential cycles rather than continuous flow.

Compact plastic housing

The 5.79 x 3.7 x 2.13 inch plastic body survives a five-foot drop test, indicating robust everyday durability. Two brass needles stow inside a top-side compartment, reducing the chance of loss during transport. USB-C charging uses any standard wall adapter, and the package includes a cable and manual for immediate use.

Questions about this item

How do I choose between the four preset inflation modes and the custom mode on the P300 pump?

The presets cover footballs, basketballs and soccer balls with one custom slot for any ball between 2 and 17 PSI, so pick the sport preset that matches your ball or use custom for other types.

What does the ±0.3 PSI accuracy mean when I am actually inflating a ball?

The sensor stops the pump within three-tenths of a PSI of the target you set, giving repeatable pressure for consistent bounce and feel.

How does the USB-C charging port affect how quickly I can recharge the pump?

The pump charges from any USB-C wall charger, so recharge speed depends on the charger you already own rather than a proprietary adapter.
