fully charged, the battery icon would stop ashing.
A. Charge with Solar Charging Cable
1. Place your solar panel somewhere that it can receive direct sunlight and abundant
sunshine.
2. Make sure that the open-circuit voltage of the solar panel falls within 14-40V. The
maximum input power of this product is 60W(Max).
3. Connect the solar panel and the product using solar charging cable. Make sure that
the solar charging cable is correctly connected, forming a solid contact with the input
port of the product.
4. The product comes with a built-in advanced control circuit. When the battery is fully
charged, it will stop charging itself automatically.
Note: DC7909 to MC4 Cable is not included,you need to purchase it separately.
B. Charge with AC Adapter
To charge the product with our attached AC adapter( please do not use the third-party
AC adapter to charge our power station, or use our AC adapter to charge other product),
insert one end of the adapter into wall outlet and insert the other end to the input port of
the product.
When the product is being charged, you can monitor the battery status by checking the
battery icon on the LCD screen. The product comes with a built-in advanced control
circuit. When the battery is fully charged, it will stop charging itself automatically.
C. Charge with Car Charger
Please use the original car charger. Insert one end of the car charger to the car cigarette
lighter receptacle and insert the other end to the input port of the product. The battery
icon will blink to indicate that the product is being charged normally.
Note:
●You cannot fully charge the product when the car charger is connected to a 12V car
battery, but you can fully charge it when the car charger is connected to a 24V car
battery.
●It is best to charge while your car engine is started.
●Q&A
Q1: How to check charging status?
The battery icon indicates the battery level of this product. The battery level is displayed

EN-06
in 5 segments. Each segment indicates 20% of the battery capacity. When battery is
being charged, the icon would ash. When the battery is fully charged, the icon would
stop ashing and all 5 segments will be lled.
Q2: How to charge other electronic devices?
1. You need to know the working efciency of your electronic devices. You can check the
user manual of your electronic device or search online for such information.
2. You need to check the power at each output port. For example, the power at AC
output port is provided by the built-in inverter of the product, whose maximum rated
output power is 120W(Max). This means that if the power of connected electronic
device is over 120W for a long period, the inverter will shut down output.
Q3: What is Depth of Discharge (DOD)?
To prolong battery life, we set the DOD of this portable power generator to 90%, which
means only 90% of the battery capacity (200Wh) can be discharged. 10% of the energy
is reserved so that the battery will not be damaged due to over-discharge.
Q4: Did it Support Charge and Discharge Simultaneously?
Yes, this power station can be discharged while charging. But for better protect the life-
span of the battery, we do not suggest you use this pass-through function long term.
Q5: Can I Charge the Power Station with Two Solar Panel in
Series?
Yes, you can. But make sure the total open circuit voltage (OCV) is no more than 40V.
otherwise it may power off automatically or cause damage.
Q6: How to Extend the Charge Time for CPAP?
We suggest turn off the humidier/heater and set a lower pressure to get a longer
charge time for CPAP.
●50Hz/60Hz Frequency Selection
Step 1: Press the power button, DC button and AC button at the same time. The LCD
screen would light up and display the current frequency (50Hz or 60Hz). Release
the buttons and move on to the next step.
Step 2: Long press DC button or AC button to select between 50Hz and 60Hz. The
frequency displayed on LCD would change accordingly.
Step 3: Once the desired frequency is selected, press AC and DC power button at the
same time to conrm the choice. When the setting is done, repeat Step 1 to
check the current frequency.

Trouble-shooting
Note: If DC 12V output port is overloaded or short-circuited, BMS protection may be
triggered. As a result, the product will shut down and cannot be turned on. In this case,
you need to charge the product to activate it.
