Latest company news about Interpreting the Meaning of Identification on Power Adapters

In our daily use of electronic devices, power adapters are indispensable accessories. However, have you noticed any markings on the adapter? These logos actually contain important information, which helps us better understand and use adapters correctly. This article will take you to interpret the common markings and meanings on power adapters.


1. Voltage (V)
The "V" symbol on the adapter represents voltage, such as "AC 100-240V". This means that the adapter can adapt to the input voltage range of the power supply, from 100V to 240V. The voltage standards vary in different countries and regions, and this label tells us that the adapter can work in various voltage environments.

2. Current (A)
The "A" symbol represents the current, such as "DC 5V 2A". This indicates that the current output by the adapter is 2 amperes (A), which can also be considered as the current required by the device. The correct current is a key factor in ensuring the normal operation of the device, and too small a current may cause the device to fail to charge or operate improperly.

3. Power (W)
The "W" symbol on the adapter represents power, such as "65W". Power represents the maximum output power that the adapter can provide. The power demand of the device should be matched with the power of the adapter. Excessive power may cause the adapter to overheat or fail to meet the device's needs.

4. Frequency (Hz)
The "Hz" symbol represents the frequency, such as "50-60Hz". This indicates the power frequency range that the adapter can adapt to. The power frequency may vary in different countries or regions, and this indicator tells us that the adapter can operate normally at different frequencies.

5. Certification mark
Some markings on the adapter also indicate that it has passed specific certifications, such as "CE" (European certification), "FCC" (Federal Communications Commission certification), "CCC" (China Compulsory Product Certification), etc. These authentication marks mean that the adapter meets relevant standards and security requirements, making it more reliable and trustworthy when used.


The markings on the power adapter are of great significance, as they tell us the voltage range, current, power, frequency, and corresponding certification information of the adapter. Understanding these markings enables better selection and use of adapters to ensure safe and stable operation of the device. Whether at home, in the office, or during travel, the correct use of adapters is the key to ensuring the normal operation of electronic devices.
