POWNYM A7 Portable Tire Inflator - 150 PSI Cordless & Rechargeable Air Pump

POWNYM A7 Portable Tire Inflator — 150 PSI Cordless Air Compressor with Smart Auto-Stop

Keep your tires at peak pressure wherever you are. The POWNYM A7 portable tire inflator packs a powerful 150 PSI cordless motor, precision digital pressure gauge, and intelligent auto-stop technology into a compact design that fits in your trunk or glove box. Whether you're topping off a daily commuter, inflating motorcycle tires on a weekend ride, or pumping up sports equipment at the park, the A7 delivers accurate, hassle-free inflation every time.

Built for Real-World Convenience

Gas station air pumps are unreliable, crowded, and often out of order. The POWNYM A7 eliminates that dependency completely. Its rechargeable lithium battery gives you 30+ minutes of cordless runtime — enough for 4 to 6 full car tire inflations on a single charge. The backlit LCD screen displays real-time pressure with ±1 PSI accuracy, and the preset auto-stop function shuts off inflation exactly at your target pressure, so you never over-inflate or under-inflate.

Frequently Asked Questions

Q: How many tires can I inflate on one charge?
A: Approximately 4–6 standard car tires from low pressure (20 PSI) to full (35 PSI) on a single battery charge.

Q: Does the A7 work on SUV tires?
A: Yes. The 150 PSI capacity easily handles SUV tires (typically 30–40 PSI). For heavy-duty truck tires exceeding 80 PSI, we recommend our higher-capacity models.

Q: What happens if I set the wrong pressure?
A: Simply re-set the target PSI on the LCD before starting. The auto-stop function ensures the inflator stops at exactly the pressure you select.

Q: Can I use it while it's charging?
A: For best performance, we recommend fully charging before use. However, the A7 can inflate tires while connected to a USB-C power source.
