A1: The AC output port can only charge or power devices that operate at less than 200W. Incompatible with appliances that require more than 200W input such as microwave, electric grill, refrigerator, electric vehicle, air compressor, and more.

Q2: What kind of solar charger can charge this product?

A: Any 11-28V solar charger with a DC 7909 male connector.

– To preserve the battery lifespan, recharge it to 100% after every use.

– Turn on Power Saving Mode and turn off all the buttons on PowerHouse.

– We recommend recharging it 100% every month.

Q4: What should I do before using for the first time and what do I need to pay attention to?

A: Charge your portable power station to activate the battery before using for the first time. Do not use with CPAP overnight and in Power Saving mode.

Q5: Why does the power station’s battery drain even when no devices are connected?

A: When the AC and car socket control buttons are turned on, there will be a certain amount of no-load power consumption. To avoid this, make sure the control buttons are turned off, or turn on Power Saving mode when not in use.
