5th grade of protection：Circuit, contact mouth protection.Mobile phone in use, because charging wire fractures, lead by joint loosenessLoose contact is caused, it is also in fact a kind of to mobile phone that this frequently charges, and is a kind of damage to battery of mobile phone, and we can be by electricityStream, the change of voltage detect this problem, when electric current and voltage occur fluctuation and is mutated, remind user to change in time and chargeLine or maintenance mobile phone, it is to avoid problem expands.
6th grade of protection：Temperature protection.When our common mobile phones charge, when the temperature of mobile phone is too high, charger can'tOutput is closed, is still powered to mobile phone, thus there is potential safety hazard, it is possible to which continuing power supply can cause mobile phone to occur generating heatFire.We, when temperature is more than predetermined value, cut off voltage output, to protect hand by the temperature at thermo-sensitive resistor monitoring cell-phone endMachine.
7th grade of protection：Full of electric protection.After mobile phone is full of, charger can close output, it is to avoid be filled to mobile phone for a long timeThe hidden danger that electricity brings.
8th grade of protection:Non- mobile phone kind equipment current limliting, short-circuit charge protection.Present equipment in need can be by USB pairsIt charges, but because common mobile phone charging short circuit current point all sets higher, cannot really starting protection effect.ThisCharger is recognized during for non-cell phone apparatus, adjust automatically short circuit current parameter, the charging safety of protection equipment.
