Power ON / OFF

To power on the B210, press and hold the Power Button for about 2 seconds, the SoC indicator will light up.

The B210 has a built-in feature that allows it to power on and starts charging as soon as it detects input from a connected power source (e.g., wall outlet, solar panel, etc.).
To restart the B210, simply press and hold the Power Button for more than 2 seconds to shut down all outputs and turn off the unit. Press the button again to turn it back on.
Note: To completely turn off the B210, please disconnect all power sources, such as solar panels and adapter.

Charging

The B210 can be charged using 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 any potential damage.

5.1 Wall Outlet
Simply plug the B210 into a standard wall outlet to start charging. It typically takes about 4.8-5.3 hours for a full charge at an ambient temperature of 25°C (77°F), and the charging automatically stops once the battery is fully topped up.

5.2 Solar Panel(s)
Connect the solar panel(s) to B210 via the solar charging cable. With a continuous input of 500W, B210 will automatically stop charging in 4.5-5 hours. However, please note that the charging time may vary based on weather conditions, sunlight intensity, panel
orientation, and other variables.
Note: Make sure your solar panel(s) meet the following requirements:

Notice：

• If you unplug the solar charging cable from the B210 and you’re not using any DC outputs, the B210 will automatically shut down after about 4 hours.
  For solar panel(s) with an open circuit voltage between 60V and 145V, you can still use them to charge the B210. Simply connect the solar panel(s) to the B210 via the PV Voltage Regulator, and you can enjoy seamless and hassle-free solar charging.

5.3 Car Outlet
Connect the B210 to the vehicle’s 12V cigarette lighter port via the car charging cable.
The B210 also automatically stops charging when it’s fully charged.
Note: Make sure your vehicle meets the following conditions for charging:

• The vehicle is capable of supplying power.
• The vehicle’s engine is running during the charging process.

Attention:
The B210 has a low voltage disconnect function designed to protect your vehicle’s battery during charging. If the input voltage drops below 8V, the unit will automatically stop charging to prevent over-discharging and potential damage to the battery.
5.4 AC240 Power Station
To charge both the AC240 and B210 simultaneously, connect the two units using the battery expansion cable provided. Then, plug the AC240 into a standard wall outlet.
Attention:
It’s recommended to fully charge the B210 before connecting it to AC240.
