Initial Charging (if needed):
The JSC7100 is battery-free and does not require initial charging for storage. However, it needs to be charged from a power source before each use. Refer to the 'Operating Instructions' for charging methods.
4. Operating Instructions
Charging Options for the Unit:
The unit can be charged using one of three methods:
- From a Car Battery (12V, 7A): Connect the smart jumper cables to a car battery with at least 8V. The unit will fully charge in approximately 3 minutes.
- From a DC Charger (12V, 5A): Connect the unit to a DC charger. Full charge in approximately 3 minutes.
- From a USB-Type C Port (5V, 2A): Connect the unit to a USB-Type C power source. Full charge in approximately 30 minutes.

Jump-Starting Your Vehicle:
The unit supports two start modes: Standard Start and Forced Start.
Standard Start (for partially powered car battery):
- Connect the smart jumper cables to the OBDMATE JSC7100 unit.
- Connect the red clamp to the positive (+) terminal of your car battery and the black clamp to the negative (-) terminal.
- The unit will begin to charge from your car battery. Wait for the LCD display to show 100% charge (approx. 3 minutes).
- Press the power button on the jump starter.
- Turn on your car's ignition to start the engine.
Forced Start (for extremely low car battery voltage):
If your car battery voltage is extremely low (below 8V), the unit must be fully charged from another power source (another car battery, DC charger, or USB-C) before attempting a Forced Start.
- Ensure the jump starter unit is fully charged.
- Connect the smart jumper cables to the OBDMATE JSC7100 unit.
- Connect the red clamp to the positive (+) terminal of your car battery and the black clamp to the negative (-) terminal.
- Press and hold the power button on the jump starter for 6 seconds. The unit will initiate a 10-second countdown and emit a long beep.
- Within the 10-second countdown, turn on your car's ignition to start the engine.
LCD Display:
The integrated LCD screen provides real-time information:
- Vehicle Voltage: Displays the voltage of the connected car battery.
- Power Percentage: Shows the current charge level of the jump starter unit.
- Status Indicators: Provides visual cues for charging status and readiness.
5. Maintenance
The OBDMATE JSC7100's super capacitor technology requires minimal maintenance:
- Storage: Store the unit in a cool, dry place. Due to its battery-free design, it does not require periodic recharging during storage.
- Cleaning: Wipe the unit with a dry, soft cloth. Do not use harsh chemicals or abrasive materials.
- Temperature Range: The unit is designed to operate and be stored within temperatures from -22°F (-30°C) to 140°F (60°C).
6. Troubleshooting
If you encounter issues, refer to the following common troubleshooting tips:
| Problem | Possible Cause | Solution |
|---|---|---|
| Unit does not power on. | Unit is completely discharged. | Charge the unit using a DC charger or USB-Type C. |
| Red indicator light on smart cables. | Reverse polarity connection. | Disconnect clamps and reconnect to correct terminals (red to positive, black to negative). |
| Vehicle does not start after jump attempt. | Car battery too low for Standard Start; unit not fully charged. | Ensure unit is 100% charged. If car battery is extremely low, use Forced Start mode. |
| LCD screen shows voltage below 8V. | Car battery is severely discharged. | Charge the jump starter from another car battery or external power source before attempting to start the vehicle. |
