ETENWOLF P300 Plus Electric Ball Pump — Handheld Inflator/Deflator, 3–17 PSI, Auto-Stop

The ETENWOLF P300 Plus is a handheld electric ball pump that quickly inflates and deflates sports balls to a precise pressure you set.

Compact and engineered for accuracy, the P300 Plus combines a sensitive pressure sensor, four preset modes, and a built-in needle storage compartment so you can get balls game-ready in about a minute. Rugged housing survives typical drops, and its custom mode covers pressures from 3 to 17 PSI, making this pump practical for players, coaches, parents, and traveling teams.

How fast and accurate is the ETENWOLF P300 Plus?

The pump is designed for speed and precision: it can inflate a ball to the target pressure in roughly one minute while maintaining a tight ±0.3 psi tolerance. A highly sensitive pressure sensor continuously monitors the internal pressure and stops automatically when the set value is reached.

• Inflation time: approximately 60 seconds to target pressure
• Accuracy: ±0.3 psi for consistent results
• Auto-stop feature prevents overinflation

What kinds of balls and pressure ranges does it handle?

The P300 Plus covers common team sports using four inflation modes: basketball, football, soccer, and a custom mode that lets you set any pressure between 3 and 17 PSI. The device also remembers your last pressure setting, so repeat use is faster when preparing multiple balls.

• Presets: basketball, football, soccer
• Custom mode: adjustable from 3 to 17 PSI
• Memory: saves last-used pressure for convenience

Can it deflate balls and is it durable enough for regular use?

Yes — the P300 Plus includes an exclusive deflation function to remove air for softer play or compact storage during travel. Built to withstand everyday handling, the unit passes a 5-foot drop test and continues to function normally, adding confidence for sideline and gym use.

• Deflation mode: quickly releases air to reduce volume
• Durability: survives typical drops and rough handling
• Needle storage: two brass needles stored on top to prevent loss

How easy is it to use and carry to practices or games?

The P300 Plus prioritizes simple one-button operation: choose a preset or custom PSI, press start, and the pump automatically reaches the target. Brass needles are stored in an onboard compartment, and the pump’s shut-down memory and compact size make it well-suited for coaches, parents, and players on the move.

• One-button operation for fast setup
• Onboard needle compartment keeps accessories organized
• Portable footprint fits team bags and backpacks

Who is this for? The ETENWOLF P300 Plus is designed for coaches, club managers, parents, and active athletes who need a dependable, accurate inflator that works across multiple ball types. If you want fast inflation, reliable pressure control, and a compact tool you can toss into a bag or sideline kit, this pump provides a practical, robust solution without complicated controls.
