A mobile phone charger is an electrical device used to charge devices such as mobile phones. The output current refers to the current intensity output by the charger to the phone or other devices during the charging process. Generally speaking, the output current of mobile phone chargers is usually 1A or 2A, and most modern chargers can provide a current output of up to 2A.
The higher the output current, the faster the charging speed. However, if the current that the device can withstand is exceeded, the device may generate heat, damage, and even pose safety hazards. Therefore, when selecting a charger, it is necessary to ensure the suitability of the current.
When modern intelligent devices charge, the current is usually controlled through a built-in charging chip. If the device prompts that the battery is fully charged while charging is still ongoing while using the charger, it indicates that the current output by the charger has exceeded the device's requirements. At this time, the charger should be replaced in a timely manner to ensure the safety and lifespan of the device.
In short, when choosing a mobile phone charger, attention should be paid to the output current and the required current should be selected reasonably to avoid unnecessary damage to the device.
