Working Time Reference
Approximately, working hours equal to 300Wh multiplied 0.85 divided
the rated power of the device you want to charge. The following data is
for reference only.
Working hours = 300Wh * 0.85 / the rated power of the device.
For your information, if the power consumption of your device was 50W.
The running time will equal to 300Wh*0.85/50W=5.1 hours (rough
calculated).

Method 2: From the DC Input Port
Method 3: From the Solar Panel
The steps are roughly the same as recharging from the Type-C PD 60W
port. The differences are that you need to use an AC to DC adapter (not
included in the package, need buying separately) and plug the cable into
the DC 3.5 input port.
Step1: Unfold the solar panel on a sunny day, and connect one end of the
solar panel cable into the DC 3.5 input port;
Step2: Connect the other end of the solar panel cable to the solar panel,
and the power station will be recharged soon.
Please note that the Joyzis portable power station can be recharged by a
solar panel with a voltage of 15 to 24 volts through the 3.5mm*1.35mm
cable. With the voltage that is too high or too low, it may not work
normally.
