4. Setup
4.1 Initial Charging
Before first use, fully charge the JIYHF S4 unit. Connect the included USB-C to USB-C cable to the device's 45W USB-C port and a compatible 45W+ wall charger (not included). The unit will display its charging status. A full charge typically takes approximately 2 hours with a 45W charger.
4.2 Solar Charging
The built-in solar panel provides trickle charging. For optimal solar charging, place the unit with the solar panel facing direct sunlight. This method is primarily for maintaining charge and is slower than USB-C charging.

5. Operating Instructions
5.1 Jump Starting a Vehicle
Ensure the jump starter unit is sufficiently charged before attempting to jump start a vehicle.
- Insert: Connect the jumper cable connector firmly into the jump starter unit's designated port.
- Connect: Attach the red (+) clamp to the positive terminal of the vehicle's battery and the black (-) clamp to the negative terminal. Ensure a secure connection. The unit features spark-proof and reverse-polarity protection for safety.
- Start: Once connected, start the vehicle's engine. If the vehicle does not start immediately, wait 30 seconds before attempting again. Do not crank for more than 3 seconds per attempt.
- Remove: After the vehicle starts, disconnect the black (-) clamp first, then the red (+) clamp, and finally remove the jumper cable connector from the jump starter unit.

- Solar Panel: Keep the solar panel clean and free of debris to ensure efficient trickle charging.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Unit does not turn on/respond. | Low battery charge. | Recharge the unit fully using the USB-C port. |
| Vehicle does not jump start. | Incorrect clamp connection; severely discharged battery; vehicle engine too large. | Ensure clamps are connected correctly (red to positive, black to negative). Check unit charge. Confirm vehicle engine size is within specifications (8.0L gas / 6.0L diesel). |
| Air compressor not inflating. | Hose not securely connected; incorrect pressure setting; unit overheating. | Ensure hose and nozzle are tightly connected. Verify pressure setting. Allow unit to cool down if it has been running for an extended period. |
| Display screen is difficult to read in daylight. | Environmental lighting conditions. | Move to a shaded area or shield the screen from direct sunlight for better visibility. |
| Solar panel not charging effectively. | Insufficient sunlight; panel obstructed; panel is for trickle charge only. | Ensure direct, unobstructed sunlight. Understand that solar charging is slow and primarily for maintaining charge, not rapid recharging. |
