Will the USB night light burn with 9V5V mobile phone fast charging and power supply?

The placement is different, the table lamps are concentrated in one place, and the small lamps are astigmatized.

No, it only uses two power cables in the USB port, no data cable, and has nothing to do with the OTG function.

Thyrist, touch the thyristor control electrode, which is equivalent to giving the thyristor a trigger signal, and the light will be on.

This kind of night light using USB power supply has been designed to set a fixed current and service life, and the external side cannot increase the power supply current. Therefore, if you want to increase the current, it will directly short-circuit and burn out and end the service life.

However, many mobile phones now support night shooting.
