Release time:2023-07-13

Lei Yi'an, associate professor of the School of Physics, Peking University:

1. From the experiment, it is found that as long as the charger is connected to the circuit board, even if there is no load, it will generate a certain amount of current.

2. After it is plugged into the circuit board, it is powered on, so it consumes a certain amount of current and is always in working condition!

3. If the charger is placed on the plug board for a long time, it will continue to heat up, which will accelerate the aging of devices and materials. In this case, short circuits or high voltage breakdowns will easily occur, which will cause fire hazards.
