Thank you for contacting us. To quickly diagnose and resolve the issue with your device, please provide the following information:

Please confirm the following:

1. The specific scenario in which the issue occurs:

Scenario A: The device is unable to power connected appliances while simultaneously charging (via AC or solar input).
Scenario B: The device is unable to power connected appliances when operating solely on stored battery energy.

2. Device status information:
What is the State of Charge (SOC) displayed on the device at the time the issue occurs?

3. Is the AC output button’s indicator light illuminated?

4. Does the device’s LCD screen display any error messages or codes?

5. Information about the connected appliance(s):
Please provide the name, model, and rated power (in watts, W) of the appliance(s) that are not receiving power.

6. Basic troubleshooting step:
When using the same AC output socket, do other appliances power on and operate normally?

To help us expedite resolution, a photo or short video showing the fault condition — for example, an error code displayed on the screen — would be extremely helpful.

We understand this may take a few moments of your time, but the details you provide will directly support our ability to identify the root cause and deliver the most effective solution.
