K8 | High-Power Cordless Bike Air Pump | 150 PSI & 15L/min Airflow | 3×1000mAh Battery Long Runtime | Fast Inflation for Bike/Motorcycle/Car Tires | OEM/ODM Supported

K8- Cordless Bike/car Air Pump | 150 PSI & 15L/min Airflow | 3×1000mAh

Positioning：For Cyclists & Car Owners – 150 PSI High-Pressure Portable Bike Pump: This high-power cordless electric bike pump is designed for cyclists and car owners who demand a compact, high-pressure, and long-lasting inflator that handles both bike and car tire emergencies.
①66.6W Motor + 15L/min Airflow – Bike-Size, Car-Capable Pump：66.6W high-power motor with 18-cylinder large core delivers 15L/min airflow and 150 PSI max pressure. RTB: Inflates a 700×23C bike tire (0→120 PSI) in 1’40”, and a car tire (195/65R15, 0→35 PSI) in 9’14”.
②±1PSI Auto-Stop Accuracy – Reliable for Bike & Car Tires: ±1PSI accuracy with auto-stop ensures consistent pressure and reduces over/under-inflation complaints. RTB: Oil-isolated sensor maintains ≤1PSI accuracy after >500 inflations; temperature compensation from -10°C to 60°C.
③Cool-Touch Design (<50°C) – Safe for Multi-Tire Sessions: Housing temperature stays below 50°C even during continuous high-pressure use. RTB: High-efficiency motor and rapid inflation reduce heat buildup; suitable for multi-tire or high-frequency scenarios.
Reliability：Long-Runtime Battery & Stable Output – OEM/ODM & Bulk Ready： Three 1000mAh high-rate battery cells with optimized BMS ensure stable output and long runtime. RTB: Supports up to 8 full tire inflations per charge; battery life improved by 40%+ (internal tests).
