Usage
Procedure
- Ensure that the load power is within the rated power of this power station. If not, please choose a higher power station.
- To begin, press the power button and then the switch.
- When the indicator is on, the output is turned on, and the device can be charged.
- After use, please turn off the power button and charge the power station in time.
- Charging method: Insert the charger into the DC audio input port, the AC output and DC 12V output will be automatically turned off, but USB charging can be used.
- After charging to 100%, please continue charging.
- The charging function will automatically stop when charging is complete.
Operation
When using the power station, please strictly follow the operation steps:
- Place in a cool, dry location away from liquids, gases, and oils, with at least 5 cm of space around it to dissipate heat.
- Equipped with a fully automatic charger, the AC output and DC 12V output will be automatically turned off during charging; only the LED lights, USB, and wireless charging functions can be used. After charging for 6 to 8 hours, please unplug the charger before use. If it is not in use, please turn it off to save power and recharge it every three months.
- When no function is used, it will automatically shut down the POWERTEC MB3776 500Wh Portable Power Station after two minutes. You need to press the power button again to reactivate it.
- When using USB charging, if the power exceeds 5 watts, the cooling fan will work every 12 minutes. When the SB charging current is less than 5 watts and the AC power is less than 10 watts, the LCD will not display the output power.
- When the temperature inside the power station exceeds 50 degrees Celsius and the load power exceeds 20% of the rated power, the cooling fan kicks in.
- In general, an AC load device with less than its rated power can be used normally, but the startup power of some devices often exceeds their rated power.
- For example, the startup power of an inductive load device is generally 6–8 times its rated power, and the startup power of LED lamps is about dozens of times their rated power.
- If the startup power exceeds the peak power of the power station, overload protection will be triggered, and the power station will automatically shut down.
