Can I use solar panel to charge while connecting the device via AC output? Body Text
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.
Key Notes:
Total Input vs. Output Power: The solar panel’s charging power + any AC charging power (if connected to a wall outlet) must be greater than the total power drawn by your devices. Otherwise, the power station may drain faster than it charges.
Example: If your devices use 50W, and your solar panel provides 80W, the power station will charge at 30W (80W input – 50W output). If you also plug in a 100W AC charger, total input becomes 180W (80W solar + 100W AC), so net charging is 130W (180W – 50W).
Efficiency Loss: Some power loss may occur during conversion (e.g., solar DC to battery DC, or AC to DC). This is normal and typically minimal (5–10%).
