K3｜Cordless Bike Air Pump｜70W High-Pressure Direct Start｜16-Cylinder Large Core｜Max 130 PSI for Road/MTB/E-Bike｜Cars｜OEM/ODM Supported

For frequent riders & cross-vehicle users: A compact yet powerful brushless inflator with 70W motor + 16-cylinder + high-capacity battery for fast, strong, long-lasting inflation, even for cars.

①70W + 16-cylinder + 10L/min airflow + 1950mAh battery → A rare “pro-grade all-rounder” portable pump. RTB: 70W brushless motor with torque +35%, airflow efficiency +20%.

②≤±1% accuracy + Auto-Stop: Reduces over/under-inflation complaints. RTB: oil-isolated sensor stays ≤1% after >500 inflations; temperature compensation –10°C to 60°C.

③Cool-touch (<50°C): Safe to hold during continuous high-pressure use. RTB: 70W high-efficiency motor + faster inflation = less heat accumulation; housing remains cool even in high-frequency scenarios.

④High-rate battery cell + power-management algorithm ensures stable output, no power drop. RTB: Battery life improved 40%+ (per internal test); supports long trips, commutes, and frequent commercial use.
