Solar portable power box is a solar system, which consists solar panels, lithium battery, inverter, and control circuit. It is widely used because of its small size and handy weight.

INSTRUCTION:
1.Turn on/off Switch One to control power circuit. When this switch is on, a 5V direct voltage will come out from USB to use for charging cell phone and other portable electric products. We will have approximately 12V to 16V direct voltage on the other hand also can be used for providing power for nearby equipment. You will see a red indicator light blinks if there is not enough power inside.
2.There is a Switch Two, which gives control of inner inverter. Turn on Switch Two will result to a 220V alternating voltage. It can provide power for certain small device. You will see the power lights switching as well.
3.The power box will automatically provide charge at the moment that solar panels are getting power from sunshine directly. You will see solar cha light blinking indicates the power is successfully given even without turning on Switch One.
4.Please use appropriate charger for lithium battery, since it goes directly into the battery. Avoid using any charger that has higher voltage than 16.8V, or certain damage to inner circuit and battery may incur.
