EPAuto Portable 12V Digital Tire Inflator — Car & Bike Compressor, Auto Shut-Off, LED Light

The EPAuto 12V DC Portable Air Compressor Pump is a compact, vehicle-powered digital tire inflator that plugs into your car’s 12V socket to quickly and accurately inflate car and bike tires and small inflatables.

This lightweight, corded inflator is designed for drivers who want a fast, precise way to maintain tire pressure without visiting a service station. It runs from a vehicle cigarette lighter (12V DC) and includes a digital pressure readout, automatic shut-off at your set pressure, and multiple nozzle adapters for sports gear and pool toys. The unit is intended for passenger cars, sedans and midsize SUVs (engines under 3.5L) and is not suitable for light truck or heavy-duty truck tires.

How does the EPAuto inflator connect and power up in my car?

The compressor uses a 12V cigarette lighter plug and draws 10–15 amps (about 120–180W) from your vehicle’s DC outlet. There is no 110V AC plug included, so it must be powered from a compatible 12V socket. The cord length is designed for easy reach to all four tires when parked near the curb.

• Plug type: 12V DC cigarette lighter plug (no AC adapter)
• Power draw: 10–15 amps; 120–180W
• Designed for car cigarette lighter sockets; check outlet rating first

What pressure ranges and display features does the digital gauge offer?

The inflator features a digital display that shows pressure in PSI, KPA, BAR, and KG/CM, making it easy to match your vehicle manufacturer’s recommended setting. You can set a target pressure and the unit will automatically shut off when that value is reached, helping prevent over-inflation. An integrated LED flashlight helps you work in low-light conditions.

• Four display units: PSI, KPA, BAR, KG/CM
• Auto shut-off at set pressure for accurate inflation
• Built-in LED torch for nighttime use

Which tires and items can this compressor inflate?

This model is optimized for passenger car tires, bicycles, sedans and midsize SUVs (engine size under 3.5L). It includes a universal Schrader valve connector plus three additional adapters for balls, small inflatables, and other recreational gear. It is not rated for light truck (LT) or heavy truck tires.

• Compatible with car and bike Schrader valves
• Includes needle adapter for sports balls
• Short and long cone nozzles for inflatables like kayaks and pool toys
• Not suitable for truck or heavy-duty tires

What safety features and protections does it include?

The unit incorporates automatic overheat protection that shuts the compressor down if it becomes overloaded or runs too long. The auto shut-off at target pressure reduces the risk of over-inflation. These protections help extend the compressor’s life and make roadside use safer and easier.

• Overheat protection with automatic shut-off
• Auto shut-off at your chosen pressure setting
• Patent-backed design (USPTO Patent No. D875,788)

Who is this for: The EPAuto 12V DC Portable Air Compressor is a practical choice for daily drivers, cyclists, and families who want a convenient, vehicle-powered solution for maintaining proper tire pressure and inflating recreational gear. Choose this model if you need a compact, accurate inflator for passenger cars and small inflatables and if you have access to a 12V DC outlet. Do not use it for light-truck or heavy-duty truck tires.
