ETENWOLF P300 Plus P300PLUSB Electric Ball Pump, 3–17 PSI, Inflate and Deflate

At 2.5" L x 1.7" W x 3.5" H, the ETENWOLF P300 Plus is a compact electric pump for sports balls. Its rechargeable 3,200 mAh battery supports inflation and deflation. Preset ball modes and a custom pressure setting make it practical for team gear, practice, and travel.

Getting the most from it

The pump offers preset modes for footballs, basketballs, and soccer balls, plus a custom mode for balls needing a pressure from 3 to 17 PSI. A pressure sensor detects the ball’s current pressure and helps the pump reach the selected target, with stated accuracy of ±0.3 PSI. Choose the relevant mode or set a custom pressure, then use the included air hose and one of the two ball needles to connect it to the ball.

Deflation is useful when you want to soften a ball or reduce its size for packing. The pump also remembers the last pressure setting after shutdown, so a repeated task can start from the setting you used before. It cannot be powered on while charging, so unplug the charging cable before use.

What you’ll notice day to day

Instead of relying on a manual pump and judging firmness by feel, this powered option lets you select a pressure and use the sensor to guide inflation. The manufacturer states that inflation takes about one minute, and the 6.5-liter-per-minute airflow capacity supports routine ball maintenance for practices or games. For a coach preparing several balls before a session, preset modes and stored pressure settings can make it easier to repeat the same setup across the group.

The small footprint and 238 g weight make it easy to carry with sports equipment. The two brass needles store in a compartment on the pump, while the included storage bag keeps the pump and its accessories together. Customer feedback often highlights its compact size, straightforward operation, inflation speed, and pressure controls, some also appreciate the battery’s ability to support repeated uses.

When it makes sense

Choose the P300 Plus when you want a portable way to manage ball pressure without relying only on a hand pump. It suits coaches, players, and families who maintain basketballs, soccer balls, or footballs and value both inflation and deflation in one device. If your priority is a simple manual tool, a hand pump is a different approach, for selecting and repeating a pressure setting, this electric pump’s sensor, preset modes, and custom range offer a more controlled routine. Its compact size and included needles make it especially useful to keep with the balls before practice or pack for a game.
