Prime Day Deal: The ETENWOLF P300 Plus Smart Ball Pump for Basketball, Soccer, and Everyday Sports Is 29% Off
A flat ball can end a game before it starts, and eyeballing the pressure rarely gets it right. The ETENWOLF P300 Plus is a small, portable smart pump built to fix that: you dial in the pressure you want and it inflates and stops on its own, so basketballs, soccer balls, volleyballs, and footballs land at the right firmness every time. It’s the kind of thing coaches, families, and schools end up reaching for constantly — and for Prime Day, it’s 29% off.
The deal
For Prime Day — June 23–26, 2026 — the ETENWOLF P300 Plus Smart Ball Pump is 29% off, down to $24.99 (from $34.99). It’s a Prime Day deal, so a Prime membership is required, and the price ends when the event closes on June 26 (or earlier if it sells out).
What it is
The P300 Plus is a cordless, rechargeable electric ball pump with a digital display and a flexible hose. You set a target pressure anywhere from 2 to 17 PSI, and ETENWOLF says it inflates to that number and stops automatically, so there’s no over- or under-inflating by feel. A pressure memory function holds your last setting for the next ball, and the 3,200 mAh battery means you’re not tethered to an outlet. The display reads out in PSI, BAR, or KPA, and the included needle adapters let it work with multiple ball types — basketball, soccer, volleyball, and football.
How to use it
Charge it up, then attach the right needle adapter and screw it onto the ball’s valve. Set your target pressure with the plus and minus buttons — most basketballs sit around 7–9 PSI, soccer balls a bit lower — and start the pump; it runs until it hits your number and stops on its own. Because it remembers your last setting, topping off a whole bag of the same ball is quick. Toss it in a backpack or gym bag so it’s there for pre-game checks at home, on the sideline, or in the gym.
Who it’s for
It’s a natural fit for coaches managing a bin of balls, families with a few players in the house, and schools that need pressures kept consistent across a team. The portability and auto-stop make it easy for anyone who wants the right firmness without guessing. If you only inflate one ball a couple of times a year, a cheap hand pump may be all you need — and if you’re inflating car tires or large inflatables, look to a higher-volume compressor instead, since this one is purpose-built for sports balls in the 2–17 PSI range.
