Plume300W Information

The AC output ports of P300W can provide power/charge for devices with a running power not exceeding 300W. If the power requirement exceeds this limit, P300W will automatically shut down. Please check the specifications of the devices you intend to use before purchasing. The device supports simultaneous powering of all interfaces, but the total wattage of the connected devices should not exceed 480W. If the power requirement exceeds this limit, P300W will automatically shut down.
How long can P300W power my appliances?
Considering different loads have different output characteristics and the efficiency of energy transfer between the power source and the device may vary, the estimated power supply duration can be roughly calculated using the formula "Power Supply Time = 256Wh * 0.85~0.9 / Running Power of the Appliance". The actual usage may vary depending on specific circumstances. (0.85~0.9 represents the conversion efficiency, which varies depending on the type of load.)
How long does it take to fully charge P300W?
This product supports two charging methods: USB-C or DC port. For USB-C port: You can use a PD charging kit with USB-C port, supporting up to 100W charging, to fully charge it in about 3-4 hours. For DC port: Using the provided 65W power adapter takes approximately 4-5 hours to fully charge. Using a car charger/cigarette lighter takes about 3-4 hours to fully charge. Using a 100W solar panel takes about 5-6 hours to fully charge.
Why does the product lose battery even when no load is connected?
The screen, AC inverter, and DC output board of the product consume a certain amount of energy in standby mode. Therefore, please long-press the power button to completely turn off the device when it is not needed.
Which type of solar panel should I choose for my P300W?
You can use a solar panel with a DC 5521 charging connector and a total open-circuit voltage range of 12-24V in conjunction with the device for charging. For your safety, we recommend using it with 1X Egretech PSP 100W.
