Setup and Initial Charging
Before first use, fully charge the EUFAB APA 16540 Power Pack for at least 12-15 hours. Regular charging is crucial for maintaining battery life and performance.
Charging the Power Pack:
- Using the 230V AC Adapter:
- Connect the 230V AC adapter to the charging port on the power pack.
- Plug the adapter into a standard wall outlet.
- The charging indicator LED will illuminate (typically red during charging, turning green when fully charged).
- Charge until the indicator shows full charge.
- Using the 12V DC Car Charger:
- Connect the 12V DC car charger to the charging port on the power pack.
- Plug the other end into your vehicle's 12V cigarette lighter socket.
- The charging indicator LED will illuminate.
- Charge until the indicator shows full charge.
It is recommended to recharge the power pack every 2-3 months, even when not in use, to ensure optimal battery health.
Operation
1. Jump Starting a Vehicle
Use this function to start vehicles with a discharged 12V battery.
- Ensure the vehicle's ignition is OFF and all accessories (lights, radio, etc.) are turned off.
- Connect the red (+) jump start clamp to the positive (+) terminal of the vehicle's discharged battery.
- Connect the black (-) jump start clamp to a clean, unpainted metal part of the vehicle's chassis, away from the battery and fuel lines. Do NOT connect to the negative (-) battery terminal directly.
- Ensure all connections are secure.
- Turn on the power pack's jump start function (if applicable, refer to specific switch on your model).
- Attempt to start the vehicle. If it doesn't start after 5-6 seconds, wait at least 3 minutes before trying again.
- Once the vehicle starts, immediately disconnect the black (-) clamp from the chassis, then disconnect the red (+) clamp from the battery.
- Turn off the power pack.

2. Using the Air Compressor
The integrated compressor can inflate tires, sports equipment, and other inflatables.
- Ensure the power pack is adequately charged.
- Screw the compressor hose adapter onto the valve stem of the item to be inflated. For different items (e.g., bicycle tires, inflatable mattresses), use the appropriate adapter provided.
- Check the pressure gauge for the current pressure.
- Turn on the compressor switch.
- Monitor the pressure gauge closely. Once the desired pressure is reached, turn off the compressor switch.
- Unscrew the hose adapter from the valve stem.
Important: Do not over-inflate. Refer to the manufacturer's recommended pressure for the item you are inflating. Do not operate the compressor for more than 10 minutes continuously. Allow a cooling period of at least 15 minutes between uses.

3. Using the 12V DC Power Socket
The 12V DC socket can power various 12V accessories (e.g., car vacuum cleaners, portable coolers) up to a maximum current draw.
- Ensure the power pack is adequately charged.
- Plug your 12V accessory into the 12V DC socket on the power pack.
- Turn on the power pack's 12V output switch (if available).
- When finished, turn off the output switch and unplug the accessory.
Note: The 12V socket is protected by an internal fuse. If an accessory does not work, check the accessory's power requirements and the power pack's charge level.
4. Using the LED Work Light
The integrated LED light provides convenient illumination.
- Locate the switch for the LED light (refer to Figure 2).
- Toggle the switch to turn the light ON or OFF.
