1. When charging, if the hand is wet, will the call cause an electric shock?
Generally, there is no electric shock. The CE-certified phone charger was subjected to a humidity test, 93% in a humid environment, and then immediately subjected to a high-voltage test. The input port to output port and the input port to shell of the charger were subjected to a high voltage test of 3000V, and the high voltage was not output to the mobile phone. And therefore it is safe.
2. Can I answer the phone while the phone is charging?
According to the technical standards, the mobile phone and the charger should be safe when used together, and the phone should be safe when charging. However, there are many inferior chargers on the market. Such chargers cannot meet safety standards and are prone to explosion and other dangers.
So remind the user, do not buy a charger that is too cheap, look for the safety logo on the charger.
3. How is the phone explosion caused?
The explosion is caused by the battery and has nothing to do with the material of the phone itself. If there is a quality problem with the battery, the internal short circuit of the battery will vaporize and cause the battery to explode. In addition, some regular battery manufacturers will provide directional relief valve protection on the battery. If there is danger, the gas generated by electrolyte gasification can be volatilized to prevent explosion. Although the battery can’t be used, the phone won’t explode. A short circuit in normal conditions will start the leakage protection in advance and avoid injury.
4. Will it be dangerous to overcharge for a long time?
There is no risk. In the battery safety test, charging will continue for 7 hours under full charge, and the output voltage will increase to 1.06 times the standard voltage. In addition, the battery itself has a protection circuit, so there is no danger and no explosion.
5. Is the brand mobile phone charger compatible?
Yes, mobile phone chargers currently use international standards. In addition, the iPad charger with a current output of 2.1A is also fully chargeable for devices such as the iPhone, which are all safe.
