Can I use solar panel to charge while connecting the device via AC output?
Yes, most modern power stations support “pass-through charging,” meaning you can charge the unit with a solar panel while powering devices via its AC outlet. This is ideal for outdoor use (e.g., camping) where you need continuous power but want to replenish the battery with solar energy.
Total Input vs. Output Power:
The charging power of the solar panel (plus the power of an AC charger if connected to a wall outlet) must be greater than the total power drawn by your devices. Otherwise, the power station's battery will drain faster than it charges.
👉 Example: If your devices use 50W and your solar panel provides 80W, the power station will charge at a net 30W (80W input – 50W output). If you also plug in a 100W AC charger, the total input becomes 180W (80W solar + 100W AC), resulting in a net charging power of 130W (180W – 50W).
Efficiency Loss:
Some minor power loss may occur during energy conversion (e.g., solar DC to battery DC, or AC to DC). This is a normal phenomenon, typically ranging from 5% to 10%.
