MIJIA Inflatable Treasure 2D Air Compressor | Portable Tire Inflator for Car, Bicycle, Motorcycle

The MIJIA Inflatable Treasure 2D is a portable, cordless air compressor that makes inflating tires simple and fast. With a 2000mAh built-in battery and preset pressure auto-stop, you can inflate car, bicycle, and motorcycle tires anywhere without needing an external power source.

This second-generation air pump delivers a noticeable speed boost over previous models. It uses a 19mm high-precision alloy die-cast cylinder to reach up to 150psi, so you can fill a bicycle tire in about 86 seconds. The digital pressure sensor reads with ±1psi accuracy, giving you reliable real-time tire pressure readings.

The lightweight design weighs only about 490g / 17.3 oz, making it easy to carry in a backpack or store in your car. A new quick-connect valve adapter lets you attach the hose without getting your hands dirty. The through-type air duct design improves airflow and heat dissipation during use.

With six preset inflation modes, beginners can select the right pressure for their tires without guessing. The free mode remembers your custom pressure value, so you do not need to reset it each time. A built-in light helps you inflate tires at night, and the air hose automatically turns on when pulled out and off when inserted to prevent accidental operation.

Usage Scenario

You are heading out for a weekend bike ride and notice your rear tire feels low. You pull the MIJIA Inflatable Treasure 2D from your backpack, set the pressure to 60psi using the bicycle mode, and press start. The pump runs for about a minute and a half, then stops automatically when the tire reaches the correct pressure. No guessing, no over-inflating, and no need to find a gas station.

Micro Comparison

Compared to the previous MIJIA Inflatable Treasure 1S, this 2D model boosts inflation speed by about 25% thanks to a high-power strong magnetic motor and improved internal structure. It also adds a quick-connect valve adapter for easier attachment. While other portable inflators may require a power cord or lack preset pressure modes, this unit gives you cordless freedom, digital accuracy, and simple one-button operation in a lightweight package.
