Follow these steps to use the car jumpstart function:

1. Step 1: Insert the clamps cable connector into the EC8 jumpstart output port of the product.
2. Step 2: Connect the positive and negative clamps to the respective terminals of the car battery. Expect a slight spark during the connection process.
3. Step 3: Check the product display screen for the voltage reading, indicating successful connection. The car can now be started.
4. If the car starts successfully, the power output of the clamps will automatically turn off.
5. In some cases, the vehicle may require additional time (30-120 seconds) connected to the Jumpstarter for the battery to recharge before starting.

7. After use, remove the clamps and long press the Power button for 2 seconds to shut down. The product will also shut down automatically if not operated for 60 seconds.

How to Use the Voltmeter Function
To use the voltmeter function, follow these steps:

1. Connect the clamps to the product’s EC8 jumpstart output port.
2. Connect the positive and negative clamps to the respective terminals of the car battery. Ensure a secure connection.
3. The green light on the main interface will flash, and the voltage of the Jumpstarter in parallel with the car battery will be displayed.
4. To only check the voltage of the car battery, short press the Power button to exit the start mode. The Jumpstarter will enter the measurement mode, and the display will show only the voltage value of the car battery.

How to wake up the Product

Short press button or LED power button to wake up the product

How to Use the Car Jumpstart Function

1. Method one: Normal jumpstart
2. Connect the positive and negative of the product clamps to the positive and negative of the car battery respectively, and make sure the connection is good;
3. Wake up the product, short press the “LED light” button or short press the “Switch” button, if the connection is good, the green light on the display panel will be on and flashing, and the positive and negative voltages of the startup power supply in parallel with the car will be displayed at the same time. The car can be started at this time;
4. If the car starts successfully, the product will automatically turn off the power output of clamps;
5. In most cases, the vehicle will start successfully at the first start operation. Some vehicles may need to be connected to the Jumpstarter for 30~120 seconds (At this time, the product will recharge the car battery) to start the operation. If the vehicle does not start immediately , please wait 20-30 seconds, then try again, no more than 5 consecutive starts within 15 minutes;
6. After use, please remove the clamps, long press the “Power” button for 2 seconds to shut down, if the product is not operated for 60 seconds, the product will shut down automatically.

Method two: Force Start
(Safety reminder: Some safety protection mechanisms in this mode are invalid and need to be used with caution. Be sure to prevent the positive and negative from being connected together to cause a short circuit, otherwise it will lead to product damage, sparks, and other more serious consequences. You must check before operation manual)

1. When the normal start function fails, for example: the voltage of the car battery is very low (the voltage is less than 1V), you can use the forced emergency start function after checking the operating manual.
2. Step 1: Insert the Clamps cable connector into the EC8 jumpstart output port of the product.
3. Step 2: In the power-on state, long press the “Power-on + LIGHT” button for 3 seconds to enter the forced start mode. At this time, the green light on the main interface will be on, indicating that the jumpstart output is turned on. At this time, prevent the positive and negative from being connected together to cause a short circuit; (In this mode, it is required to turn on the forced start function first, and then connect the clamps to the car battery, otherwise the output cannot be turned on).
4. Step 3: Connect the positive and negative of the clamps to the positive and negative of the car battery respectively (there will be a slight spark during the connection process, which is normal), and make sure that the connection is good. At this time, the product display screen will display the voltage of the jumpstarter in parallel with the car battery, and the car can be started;
5. Short press the “Power” button to exit force start mode.

How to Use the Voltmeter Function

1. Connect the clamps to the product EC8 jumpstart output port.
2. Connect the positive and negative of the clamps to the positive and negative of the car battery respectively, and make sure the connection is good;
3. At this time, the green light on the main interface will flash, and the voltage of the Jumpstarter in parallel with the car battery will be displayed. After entering the start mode, if you want to only check the voltage of the car battery, short press the “Power” button to exit the start mode, the Jumpstarter will enter the measurement mode, and then the “green light” will go out, and the display only shows the voltage value of the car battery.
4. Disconnect the jumpstarter clamps from the car battery and exit the voltmeter function mode.
