Setup and Initial Charging

Before first use, it is recommended to fully charge your PAXCESS ROCKMAN 500W. The unit comes with several charging options to suit your needs.

Charging Methods:

• AC Wall Outlet: Connect the provided AC to DC adapter to the DC IN port on the power station and plug it into a standard wall outlet. Full charge typically takes 7.5-9 hours.
• Solar Panel: The power station features a built-in MPPT controller for efficient solar charging. Connect a compatible 60W, 100W, or 120W solar panel (sold separately) to the PV input port. Charging time is approximately 6-7 hours with a 120W solar panel under optimal sunlight.
• 12V Car Charger: Use the car charger cable to recharge the unit from your vehicle's 12V car port. This method takes about 9.5-10.5 hours. Ensure your car engine is running to avoid draining the car battery.
• USB-C PD Port: The unit can be charged via its USB-C 30W PD input, taking 10-11 hours for a full charge.
• Combined Charging: For faster charging, combine methods:
  • Wall Outlet + USB-C PD: Approximately 5.5-6.5 hours.
  • Solar + USB-C PD: Approximately 4.5-5.5 hours.

Operating Instructions

The PAXCESS ROCKMAN 500W is designed for ease of use, providing power to a wide array of devices simultaneously.

Turning On/Off and Output Control:

• To turn the entire unit ON or OFF, long-press the master Power button. This prevents accidental power activation during transport.
• To turn ON or OFF specific output sections (Car/USB (DC) or AC), press their corresponding buttons.

Connecting Devices:

The power station offers multiple output options:

• 110V AC Outlets: (1 port, 500W rated, 750W peak) Ideal for small home appliances, laptops, and sensitive electronics due to its pure sine wave output.
• 12V Car Port: (1 port, 12V/10A, 120W max) Suitable for car refrigerators, portable air compressors, and other 12V devices.
• DC Ports: (2 ports, 12V/5A, 60W max) For various DC-powered devices.
• USB-A Ports: (2 ports, 5V/3.1A) For charging smartphones, tablets, and other USB-powered devices.
• QC 3.0 USB Port: (1 port, 5-9V, 18W max) For fast charging compatible devices.
• USB-C PD Output: (1 port, 20V, 30W max) For charging USB-C powered laptops and devices.

The unit can power up to 8 devices simultaneously, with a maximum combined output of 600W. If the total power draw exceeds 500W (continuous) or 750W (peak), the unit may enter protection mode and shut off.

Understanding Power Output and Usage Time:

To estimate how long the power station can run your devices, use the following calculation:

Working time = (519Wh x 0.85) / working power of your device (in Watts)

The 0.85 factor accounts for power conversion losses. For example, a 40W mini car refrigerator could run for approximately 11 hours (519 * 0.85 / 40).

Maintenance and Storage

Proper maintenance and storage will extend the lifespan of your PAXCESS ROCKMAN 500W Portable Power Station.

• Battery Lifespan: Lithium-ion batteries typically have 500 charge cycles before their capacity drops to about 80% of new.
• Storage: For long-term storage, keep the battery fully charged every 3-6 months. Alternatively, keep it plugged in when not in use and discharge it to 50% every 3-4 months. Avoid letting the battery completely drain for extended periods, as this can negatively impact its lifespan.
• Temperature: Li-ion batteries operate best in temperatures between 32-104°F (0-40°C). Avoid charging the unit in below-freezing temperatures (0°C/32°F) as this can damage the battery and limit its overall capacity. When operating in cold conditions, the heat generated by the battery can help maintain its performance.
• Environment: Keep the power station away from water splashes, rain, and pools. It is not waterproof. Store it in a dry, cool place, ideally in a garage rather than inside the house to minimize fire risk, though this risk is low with proper BMS.
• Port Covers: Ensure all port covers are securely closed when not in use to protect against dust and spills.
• Fan Operation: The internal fan will turn on during charging or high power output to cool the unit. This is normal operation and helps prevent overheating.

Troubleshooting

If you encounter issues with your PAXCESS ROCKMAN 500W, refer to the following common solutions:

• Unit Not Turning On: Ensure the master power button is long-pressed to activate the unit. Check if the battery has sufficient charge.
• Output Port Not Working: If an AC or DC output port is not providing power, press its corresponding activation button. If an error condition (e.g., overload) is displayed on the LCD, turn OFF the respective output, resolve the cause (e.g., reduce load), and then turn it back ON.
• AC Output Not Working While Charging: Note that the AC output port cannot be used while the power station itself is being charged via a wall outlet, car charger, or solar panel. Only the DC-based outputs (USB, 12V) are functional during charging.
• Overload Protection: If a device draws more than 500W continuously or exceeds the 750W peak/surge limit, the power station will shut off as a safety precaution. Disconnect the high-power device and restart the output.
• Overheating: If the unit feels excessively hot, ensure the ventilation vents are not blocked. The internal fan should activate to cool the unit. If the fan is not working or the unit remains hot, discontinue use and contact support.
