The B210 powers on and starts charging automatically when it detects input from a connected power source (e.g., wall outlet, solar panel). To restart, press and hold the Power Button for over 2 seconds to shut down all outputs, then press again to turn it back on.

Note: To completely turn off the B210, disconnect all power sources (solar panels, adapter).

5. Charging

The B210 can be charged via a standard wall outlet, solar energy, a car power source, or in combination with the AC240 power station.

Notice:

• Double-check that all cables are firmly plugged in.
• Avoid getting plugs and ports wet to prevent damage.

5.1 Wall Outlet

Plug the B210 into a standard wall outlet to begin charging. A full charge typically takes 4.8-5.3 hours at 25°C (77°F). Charging stops automatically when the battery is fully topped up.

Diagram: Illustration of charging via a wall outlet, showing the AC adapter connected to the B210 unit.

5.2 Solar Panel(s)

Connect solar panels to the B210 using the solar charging cable. With a 500W input, charging takes approximately 4.5-5 hours. Charging time may vary based on weather, sunlight intensity, panel orientation, and other factors.

Note: Ensure your solar panels meet these requirements:

• Voc: 11V-60V
• Current: 10A Max.
• Power: 500W Max.

Notice: If the solar charging cable is unplugged and no DC outputs are in use, the B210 will shut down automatically after about 4 hours.

For solar panels with an open circuit voltage between 60V and 145V, use the PV Voltage Regulator to connect them to the B210 for charging.
