The girl was using a phone charger cable.
According to Professor Carissa Bunke, who leads the project, although the devices are low voltage, if the intensity of the current is strong enough, it can still make the victim shocked. In fact, there have been many cases where both charging and using the phone lead to fire and explosion, which have serious and even deadly consequences.
Researchers have experimented with 400 floating, unidentified iPhone chargers to check if they guarantee electrical safety requirements. The results prevented them from worrying, 99% of these charging cables did not reach the required safety level and 22 of them failed during the test.
With this alarming result, users may need to pay more attention when buying and using phone charger cables, it is best to use genuine brand name products. In addition, to avoid causing danger to themselves and those around them, users should pay attention not to charge and use the phone as well as remove the charger from the power socket when not in use.
