Associate Professor, School of Physics, Peking University Lei Yianan:

First, from the experiment found that the charger as long as the received circuit board, even if there is no load, it will produce a certain current.
Second, it is inserted on the circuit board after the power on, then it will consume a certain current, and has been in working condition!
Third, if the charger on the plug board on the long-term, it will continue to heat, so as to accelerate the aging of devices and materials, so easy to produce short-circuit or high-voltage breakdown, which triggered a fire hazard.
