Oasser Cordless Tire Inflator – Portable Air Compressor, USB-C Rechargeable, 150 PSI & Auto Shut-Off

The Oasser Cordless Tire Inflator is a compact, USB-C rechargeable air pump designed to quickly top off car, motorcycle, bicycle tires and inflatables while preventing overfilling with smart auto shut-off.

Lightweight and engineered for roadside convenience, this portable air compressor combines a 19mm precision cylinder and a powerful 390-type long-shaft motor to deliver fast inflation up to 150 PSI. Its dual LCD screens show both your preset target pressure and the real-time pressure reading, and the built-in sensor stops automatically when the set value is reached. Small enough to store in a trunk or garage, the unit includes multiple nozzle adapters, a quick-lock chuck for easy valve attachment, and a USB-C port so you can recharge quickly or use the device as an emergency power bank.

How fast will this pump inflate a typical car tire?

The Oasser inflator uses a 19mm cylinder and a high-efficiency motor to reduce wait time. Typical examples include inflating a 195/60 R15 tire from 29 to 36 PSI in under two minutes and bringing a flat 185/70 R14 up to 29 PSI in around 6–7 minutes.

• Max pressure: 150 PSI (10.3 Bar)
• 195/60 R15: 29 → 36 PSI in <2 minutes
• 185/70 R14: flat → 29 PSI in ~6–7 minutes
• Suitable for cars, SUVs, motorcycles, bicycles, sports balls

What safety and accuracy features prevent over-inflation?

Built-in high-precision sensors monitor pressure continuously and the smart auto shut-off halts inflation once your chosen target is reached. Dual LCD displays let you preset a pressure value while viewing current pressure, helping avoid guesswork even in bright daylight.

• Dual-screen layout: target and live pressure visible simultaneously
• Automatic shut-off at preset pressure to protect tires
• Memory function recalls the last-used setting for quick reuse
• Auto power-off after 1 minute of inactivity to save battery

How long does the battery last and can it charge other devices?

The internal rechargeable battery fully recharges in about four hours via USB-C and offers multiple inflations per charge depending on the item. A 5V/1A USB output lets you top off phones or small electronics in emergencies while on the road.

• Full charge time: ~4 hours via USB-C
• One charge capacity: up to 6 car tires (185/70R14) or 12 motorcycles
• Also inflates roughly 20 bikes or 46 basketballs per charge
• USB output acts as a 5V/1A power bank for small devices

What accessories and user conveniences are included?

Oasser supplies practical attachments and user-friendly components for quick setup and night-time use. The quick-lock chuck locks onto valves without twisting, reducing air loss and simplifying one-handed operation, while the three-mode LED light helps with roadside visibility.

• Includes hose, USB-C cable, storage bag and multiple nozzles
• Quick-lock air chuck for fast, secure valve connection
• 3-mode LED: steady, slow flash, SOS fast flash for emergencies
• Compact dimensions: 5.1 × 3.5 × 1.9 inches for easy storage

Who is this for? The Oasser Cordless Tire Inflator suits drivers who want a dependable, compact inflator for routine tire maintenance and emergency top-offs — commuters, weekend road-trippers, motorcycle riders, cyclists, and families who like to keep sports gear and inflatables ready. It’s ideal for anyone who values fast inflation, clear digital feedback, portability, and USB-C charging, but it is not intended for very large tires such as RV or trailer tires, or large inflatable boats and islands.
