Product Information

Product Specifications

Features

Voltage parameters:

DC 5V: Indicates that the charger uses a direct current power supply with a voltage of 5 volts. DC (Direct Current) is the abbreviation of direct current, indicating that the direction of the current remains unchanged. 5V is the standard voltage required for charging most electronic devices.

Input frequency:

50/60Hz: Indicates that the charger supports 50 Hz and 60 Hz AC input. This feature allows the charger to be used worldwide because the power system frequencies of different countries and regions are different, such as 50Hz in my country and 60Hz in Japan.

Output voltage and current:

5V 3A: Indicates that the charger has a voltage of 5V and a maximum current of 3 amperes when outputting. A+C may indicate that the charger supports multiple charging interfaces, such as USB-A and USB-C.

Output power:

15W: Indicates that the maximum output power of the charger is 15 watts. Output power is the maximum energy that the charger can provide to electronic devices and is one of the important indicators for evaluating charger performance.
