Nowadays, products are popularly called guards. Let’s introduce a charging guard to everyone. It is not a charger but a guard that protects the battery. I believe that many people’s mobile phones are fully charged. Afterwards, we often forget to unplug the power supply. No matter how good the charger is, it will have some impact on the life of the battery. A charger of poor quality will overcharge the battery and cause damage. This battery guard can automatically cut off the power after the battery is fully charged. It is connected between the data cable and the charger. When it detects that the battery is full, it will disconnect immediately to prevent overcharging. It is equivalent to unplugging your mobile phone. It is very safe and reliable. .
