5. Setup and Initial Charging

Before using the CARTREND Power Station for the first time, it must be fully charged. It is recommended to fully charge the unit after each use and at least every 3 months to maintain battery health.

5.1 Charging the Internal Battery

1. Ensure the Power Station's ON/OFF switch is in the OFF position.
2. Connect the AC charging adapter to the charging port on the Power Station.
3. Plug the AC charging adapter into a standard 230V AC wall outlet.
4. Allow the unit to charge until the battery status indicator shows a full charge. This may take several hours for the initial charge.
5. Once fully charged, disconnect the AC adapter from the wall outlet, then from the Power Station.
6. Alternatively, you can charge the unit using the DC charging cable from a 12V vehicle outlet. Follow similar steps, ensuring the vehicle engine is running for optimal charging.

Note: Do not overcharge the unit. Disconnect once fully charged. The internal battery is a sealed lead-acid type and requires regular charging to prevent sulfation and extend its lifespan.

6. Operating Instructions

6.1 Jump-Starting a Vehicle

Before jump-starting, ensure the Power Station is fully charged and the vehicle's ignition is off.

1. Ensure the Power Station's ON/OFF switch is in the OFF position.
2. Connect the RED (+) positive clamp to the positive terminal of the vehicle's discharged battery.
3. Connect the BLACK (-) negative clamp to a solid, unpainted metal part of the vehicle's chassis, away from the battery and fuel lines. Do not connect directly to the negative battery terminal.
4. Switch the Power Station's ON/OFF switch to the ON position.
5. Attempt to start the vehicle. If it does not start after 5-10 seconds, wait at least 3 minutes before trying again to prevent overheating the Power Station.
6. Once the vehicle starts, immediately switch the Power Station's ON/OFF switch to the OFF position.
7. Disconnect the BLACK (-) negative clamp first, then the RED (+) positive clamp.
8. Recharge the Power Station as soon as possible after jump-starting.

6.2 Using the Air Compressor

The integrated air compressor can inflate vehicle tires, sports equipment, and other inflatables.

1. Ensure the Power Station's ON/OFF switch is in the ON position.
2. Attach the compressor hose nozzle securely to the item you wish to inflate. Use appropriate adapter nozzles if necessary (e.g., for bicycle tires or balls).
3. Activate the compressor switch (refer to the control panel diagram for location).
4. Monitor the pressure gauge and inflate to the recommended pressure.
5. Once the desired pressure is reached, switch off the compressor and disconnect the nozzle.
6. Important: Do not operate the compressor continuously for more than 10 minutes. Allow it to cool down for at least 15 minutes between uses to prevent overheating.

6.3 Using the Work Light

The integrated work light provides convenient illumination.

• Ensure the Power Station's ON/OFF switch is in the ON position.
• Locate the work light switch on the control panel and turn it on.
• Turn off the light when not in use to conserve battery power.

6.4 Using the 12V DC Output

The 12V DC output socket can power various 12V accessories (e.g., car vacuum cleaners, portable coolers).

• Ensure the Power Station's ON/OFF switch is in the ON position.
• Plug your 12V accessory into the DC output socket.
• Ensure the accessory's power consumption does not exceed the unit's maximum output capacity.
• Disconnect the accessory when finished to conserve battery power.
