A:AnswerThanks for your interest in our product! The C300X has a capacity of 288Wh and supports up to 100W solar input. For the best charging experience, we recommend pairing it with one of our PS100 or PS60 solar panels.
If you use the PS100, the recharge time is typically around 3 hours under ideal sunlight conditions. Actual charging time may vary depending on sunlight intensity, weather, panel angle, and other environmental factors.
