*Weight reduced by 50%: The Mijia Air Pump 2 weighs approximately 490g, while the Mijia Portable Air Pump weighs about 240g—a weight reduction of roughly 50%.
*Inflation Speed: Approximately 60 Seconds: Fully charged, in bicycle mode, inflating a 700x23C bicycle tire from 0 psi to 80 psi takes approximately 60 seconds (±10%).
*Fully charged capacity: 8 bicycle tire inflations: In bicycle mode with a full charge, it can inflate a 700x23C bicycle tire from 0 psi to 80 psi up to 8 times.
*Bicycle tire top-up x23: With a full charge, in bicycle mode, topping up a 700x23C bicycle tire from 60psi to 80psi can be completed 23 times.
*Approx. 20 seconds/tire: Fully charged, in Bike mode, inflating a 700x23C bicycle tire from 60psi to 80psi takes approximately 20 seconds.
*E-bike tire inflation x43: With a full charge, in motorcycle/e-bike mode, inflating a 65/90-10 e-bike tire from 2.0 bar to 2.5 bar allows for 43 inflations.
*Approx. 10 seconds/tire: Fully charged, in Motorcycle/E-bike mode, inflating a 65/90-10 e-bike tire from 2.0 bar to 2.5 bar takes about 10 seconds.
*Automatically stops at target pressure—no supervision required: If no preset pressure is set, do not leave during inflation to prevent overinflation.
*±1 psi accurate tire pressure detection: When inflating a 1L air tank equipped with a 0.1 psi digital pressure gauge, the displayed pressure difference between this product and the gauge is <1 psi after inflation stops and readings stabilize.
*Unless otherwise specified, all data on this page originates from external laboratory testing conducted under the following conditions: temperature 25±2°C, humidity 65±15% RH, atmospheric pressure approximately 997 hPa. Actual performance may vary slightly due to differing environmental conditions.
