Oasser Portable Tire Inflator Air Compressor — Rechargeable 150 PSI, Dual-Display, Auto-Stop (Compact)

Oasser Tire Inflator is a compact, rechargeable air compressor that quickly inflates car, motorcycle, and bicycle tires with preset pressure modes and an automatic shutoff. This lightweight pump blends faster inflation speed with a small footprint, making it easy to carry for roadside fixes, weekend rides, or daily car maintenance. It features dual screens to show both preset and live pressure, five preset modes for common uses, and a built-in LED light for low-light situations. The unit’s rechargeable battery and reverse charging capability let you top up small devices on the go while a collection of nozzles extends compatibility to sports equipment and bikes.

How fast and accurate is this inflator?

The Oasser inflator uses a high-efficiency 19-cylinder motor that delivers up to 150 PSI and achieves about 40% faster inflation than typical 17-cylinder models. Dual displays let you set a target pressure and monitor the real-time value as it fills. An auto-stop feature prevents overinflation once your selected pressure is reached.

• Inflates a 185/70R14 tire from 29 to 36 PSI in about 1.5 minutes
• Dual screens show preset and live pressure simultaneously
• Auto-stop after reaching target pressure for safety

What devices and valves will it work with?

Oasser includes three quick-change nozzles for a wide range of valves, so it works for car tires, motorcycles, bicycles, and sports balls. It supports pressure units in PSI, Bar, KPa, and Kg/cm², and retains the last used setting with its memory function. Note it’s not designed for very large, low-pressure inflatables like air mattresses or truck/RV tires.

• Five preset modes: Car, Motorcycle, Bicycle, Ball, Custom
• Three nozzle adapters for Schrader-like valves and sports inflatables
• Not suitable for large-volume low-pressure items such as pool floats

How portable is the device for travel and emergencies?

The pump measures about 3.6 x 1.9 x 5.1 inches and weighs roughly 1.39 lb, making it easy to store in a glovebox or backpack. It comes with a compact storage bag and a 30 cm extended hose that improves reach when inflating tires. A three-mode LED—steady, flashing, and SOS—adds useful illumination for roadside or low-light situations.

• Compact dimensions and included storage bag for easy transport
• 30 cm extended hose for comfortable, hands-free use
• Built-in LED with steady, flashing, and SOS modes for emergencies

How long does the battery last and how do I charge it?

The built-in battery fully charges in about five hours using the bidirectional Type-C port and also works as a reverse-power bank to charge small devices. The pump powers off automatically after 90 seconds of inactivity to save battery. For best results, fully charge the unit before first use and keep a charger handy for travel.

• Full charge time: approximately 5 hours via Type-C
• Can function as a power bank for phones and small electronics
• Auto power-off after 90 seconds of inactivity conserves battery

Who is this for This inflator is ideal for drivers, cyclists, and outdoor enthusiasts who want a reliable, portable way to maintain tire pressure and inflate small sports equipment. If you need quick, precise inflation for standard car tires, motorbikes, bikes, and balls—and value compact size, preset modes, and rechargeable convenience—this Oasser model fits well. It is not intended as a replacement for high-flow, low-pressure pumps required by large inflatables or heavy commercial vehicle tires.

FAQ

Q: Can this inflate large RV or truck tires?

A: No. It reaches high PSI but is designed for smaller car and motorcycle tires, not large-volume low-pressure tires like RVs or trucks.

Q: How do I set a target pressure?

A: Choose the appropriate preset mode or Custom, set the desired pressure unit and value, then press start; the pump stops automatically at the set pressure.
