A:Answer Hello,
Thank you for your question about our GV30 portable projector. To use your car charger, kindly purchase a power inverter that is compatible with it. The power inverter should have an output of "100V-240V ~ 50/60Hz, 1.5A". Please note that the car charger is not intended for charging large electronic devices, and the electricity it provides may not be consistent.
For charging the projector using the USB-C port, you will need power delivery that is capable of supporting 45W, 15V, and 3A.
Warm Regards,
BenQ Support
