Safety Instructions

Please read the following instructions carefully before using the product to ensure safe operation.

Follow all instructions in this manual to ensure safe use of the Lokithor. Failure to comply with these instructions or improper use of Lokithor products may result in malfunction or personal injury.
Lokithor is designed for starting 12V vehicles and should not be used for vehicles exceeding the product specifications for voltage or displacement.
WARNING: When using FORCED START mode, all Lokithor safety features are disabled. Exercise extreme caution. Do not allow the clamps to short circuit or touch each other. Read and understand all safety precautions before using the forced start mode.
To ensure the best lifespan of your Lokithor product, we recommend a quarterly maintenance program. Fully charge your new Lokithor product before use. Check the device's charge level every three months and recharge if necessary. You can also use the power bank function during this time to discharge the battery to about 50% and then recharge the product fully before placing it back in your vehicle. This good practice will help ensure that Lokithor is always ready for your vehicle in the next emergency.
Do not use the product if it is damaged. Discontinue use if the product has been damaged from impact, collision, or any other physical damage. Using a damaged product may cause a hazardous situation.
Do not use the Lokithor while it is charging.
Do not disassemble the jump starter. There are no user-serviceable parts inside the device.
Exercise extreme caution when working near car batteries and the jump starter. Avoid dropping metal objects onto the battery terminals while using the Lokithor. Any metal object can cause a dangerous short circuit, which may lead to device damage and/or explosion.
When starting a vehicle, ensure that the positive (+) and negative (-) clamps are making good contact with the battery's positive (+) and negative (-) terminals.
Do not allow sparks and/or flames to come into contact with the jump starter or the engine. Always connect the Lokithor to the vehicle's battery before attempting to start it or engage the vehicle's quick start function.
Prevent damage to the device from short circuits and sparks. Do not allow the clamps to touch each other or connect the clamps to the same piece of metal (short circuit).
The device is not intended for use by children. Do not leave the jump starter in a location accessible to children.
Do not expose the device to rain or snow.
Do not expose the product to extreme temperatures for extended periods (above 55°C or below -10°C, humidity >80%).
When not in use, store the device in a cool, dry place.
Ensure the device is well-maintained. Recharge the device promptly after use or when depleted. Failure to do so may result in over-discharge, leading to low internal battery voltage or power failure. Extended periods of low or no power may cause permanent malfunction of the product.

Product Usage

1. Connecting the Jump Starter

Press the LED light button briefly or the power button.

2. Starting the Engine

2.1 Mode 1: 12V Automatic Start

Ensure the vehicle's electrical and starting system is 12-volt.

Connect the positive (+) and negative (-) clamps to the corresponding terminals of the vehicle's battery, ensuring a good connection.

Activate the jump starter by briefly pressing the power button or the LED light button. The jump starter will count down from ten to check the battery and connection. If the start indicator on the display flashes and the battery voltage is shown, the vehicle is ready to be started.

If the vehicle starts, exit the jump start mode by briefly pressing the power button and then disconnect the battery clamps.

In most cases, the vehicle will start immediately after connecting the jump starter. If the vehicle does not start immediately, ensure the battery clamps are securely connected to the battery terminals and try again. Do not attempt to start the vehicle more than five times within a 15-minute period.

Disconnect the battery clamps from the vehicle's battery immediately after starting. Turn off the jump starter by pressing and holding the power button for two seconds. If the jump starter is not used for 60 seconds, it will automatically shut off.

2.2 Mode 2: Forced Start

SAFETY INFORMATION: When using forced start mode, the spark-proof function and some safety mechanisms are disabled. Ensure you connect the positive (+) and negative (-) terminals correctly. If the cables are connected incorrectly and forced start mode is used, the vehicle, jump starter, or both may be damaged. Read the user manual instructions carefully before using forced start mode. Exercise caution when using forced start mode.

If the automatic start function does not detect the vehicle's battery, use the forced start mode. Follow the instructions below carefully for the function to work correctly.

Step 1: Connect the battery clamps to the EC8 connector of the jump starter.

Step 2: Connect the red (+) clamp to the positive (+) terminal of the vehicle's battery. When the device is on, press and hold for five seconds to activate forced start mode. The start indicator light will illuminate, indicating that the battery clamps have power.

To exit, press the power button or the LED light button.

Step 3: Connect the black (-) clamp to the negative (-) terminal of the vehicle's battery. Ensure a good connection. The total voltage of the jump starter connected in parallel with the vehicle will be displayed on the screen. Start the vehicle.

3. Battery Clamp Connection Status (ConnectMax)

When connecting the battery clamps to the vehicle battery in automatic start mode, a 10-second countdown begins for the jump starter to check the battery and connection. If the connection impedance is low, the clamp status indicator light will be green. If the connection impedance is high, the clamp status indicator light will be yellow. You can adjust the clamp connection during the countdown. After 10 seconds, exit start mode and reconnect the battery clamps for impedance measurement.

When the jump starter is in forced start mode, the clamp status indicator light will flash yellow during operation as a warning.

4. Using the Voltage Meter Function

Connect the battery clamps to the jump starter.

Connect the red (+) clamp to the positive (+) terminal and the black (-) clamp to the negative (-) terminal of the vehicle's battery. Ensure they are securely attached.

After the 10-second detection is complete, the start indicator will illuminate, and the vehicle's battery voltage will be displayed on the screen. To exit the voltage meter function, disconnect the clamps from the battery terminals.

5. Using the LED Light

Press and hold the LED light button for one second to turn on the LED light.

Cycle through the LED light modes (on, strobe, SOS, and off) by briefly pressing the LED light button.

Turn off the LED light by pressing and holding the LED light button for two seconds.

6. Charging the Jump Starter

Accessories: Power adapter (PD 2.0/PD 3.0), USB-C to USB-C cable, USB-A to USB-C cable.

Connect the USB-A end of the cable to the power adapter and the USB-C end to the product's USB-C charging port. When the power indicator on the display lights up, it means the jump starter is charging.

If the jump starter's power is low or depleted, charge it promptly to prevent the battery voltage from dropping.

Do not store the jump starter with a depleted battery. This may lead to the battery becoming unchargeable.

7. Charging a Mobile Phone via the 5V USB-A Port

Accessories: USB-A to USB-C cable, mobile phone.

Connect the USB-A end of the cable to the jump starter and the USB-C end to the mobile phone's USB-C charging port.

8. Using the DC Input

Accessories: Car charger - DC adapter.

Connect the female DC end to the jump starter's DC charging port and the car charger adapter to the vehicle's cigarette lighter to charge the jump starter.
