K2｜Brushless Cordless Mini Bike Inflator｜High-Pressure Start｜±1% Digital Gauge Auto-Stop｜Up to 130 PSI｜OEM/ODM Ready

$ 20

Positioning｜For frequent riders: A compact brushless inflator built for fast, heat-resistant, on-the-go top-ups.

①｜120 PSI High-Pressure Start + ~2 min (700×23C → 120 PSI): Faster roadside recovery; no deflation needed even >80 PSI. RTB: brushless torque +35%, airflow efficiency +20%.

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

③｜Cool-touch (<55°C): Safer hand-held use during continuous high-pressure inflation. RTB: quantified thermal design (heat path optimized).

④｜Reliability｜Longer life + batch stability: Lower warranty risk for bulk purchase. RTB: motor control algorithm (≥+15% speed in high-pressure), high-temp components, dual overheat protection; continuous-life improvement 40%+ (per internal test/Q&A).
