The KESS3 External Battery Power Supply is an accessory designed specifically for the KESS3 ECU tuning tool. It delivers extra power to the KESS3, enabling prolonged usage without needing a direct connection to a vehicle. This is particularly beneficial for tuners who work in remote locations with limited access to electrical outlets.

For reliable performance, ensure you purchase only original, high-quality cables. These cables guarantee a stable connection between the KESS3 programming tool and the vehicle's diagnostic port.
