Hi,I apologize for the poor user experience. If the device is unable to support power supply, please check the following items: 1. Ensure that the power supply side can provide at least 12V5A. 2. Make sure that the power switches for both AM5N and ASIAIR are manually turned on. 3. If ASIAIR powers on normally, please check if the power output function on the ASIAIR page is working properly. 4. If the issue still cannot be resolved, please contact your agent or ZWO after-sales personnel for further assistance.
