4. Use Guide

4.1 Initial Charging

1. Before first use, fully charge the unit using the provided AC wall charger or 12V car charger.
2. Connect the charger to the unit's charging port. The display should indicate charging status.
3. Allow several hours for a complete charge. Refer to the display for a full battery indicator.

4.2 Jump Starting a Vehicle

1. Position the Unit: Place the jump starter on a stable, flat surface near the vehicle's battery, but at least 18 inches away from the battery.
2. Power On: Turn on the jump starter unit.
3. Connect Clamps - CORRECT ORDER IS CRITICAL:
   1. Connect the RED (Positive +) clamp to the POSITIVE (+) terminal of the dead vehicle battery.
   2. Connect the BLACK (Negative -) clamp to a clean, unpainted metal part of the vehicle's engine block or chassis (a ground point). Do NOT connect to the negative battery terminal.
4. Start the Vehicle: Get into the vehicle and start the engine. It should start within a few seconds.
5. Disconnect Clamps - REVERSE ORDER:
   1. Disconnect the BLACK (Negative -) clamp from the vehicle's ground point.
   2. Disconnect the RED (Positive +) clamp from the battery's positive terminal.
6. Power Off & Recharge: Turn off the jump starter. Recharge it as soon as possible.

Compatible Vehicles: 12V cars, SUVs, trucks, pickups, motorcycles with gasoline or diesel engines up to 8.0L displacement.

4.3 Using the Air Compressor

1. Attach Hose & Nozzle: Connect the air compressor hose to the unit's port. Select the appropriate valve connector for your item (tire, ball, mattress, etc.) and attach it to the other end of the hose.
2. Connect to Item: Attach the valve connector securely to the tire valve or item's air inlet.
3. Set Target Pressure: The unit may have an automatic shut-off or require monitoring. Know your target PSI (e.g., 35 PSI for a car tire).
4. Power On & Inflate: Turn on the unit and select the compressor function if necessary. The compressor will start. Monitor the pressure gauge on the unit's display.
5. Stop & Disconnect: When the desired pressure is reached, turn off the compressor. Disconnect the hose from the item first, then from the unit.

Max Pressure: 260 PSI. Do not exceed the maximum pressure rating of the item you are inflating.

4.4 Charging Electronic Devices

• Via USB: Use a standard USB cable to connect your phone, tablet, or other device to one of the unit's 5V/2.1A USB ports. The unit must be powered on.
• Via 12V DC Port: Use an appropriate 12V adapter (not included for specific devices) to power equipment like a car refrigerator or vacuum cleaner from the 12V/10A DC output port.

4.5 Using the LED Light

Press the light button (often integrated with the power button or separate) to turn on the built-in LED light. It may have multiple modes (steady, flashing). Use it to illuminate your workspace in dark conditions.
