YES. It will come with partially charged. However, we highly recommend you fully recharge your device before the first use.
Note: The jump starter need at least 20% battery power to start your car.
Even though our product can start dead battery vehicles when the battery level of the jump starter is 20%, we still suggest you recharge the jump starter to above 80% for the best performance. When starting a completely dead battery, the car engine requires more cranking power.
