When purchasing an AC adapter power China, you should pay attention to the following aspects:
1. Pay attention to the voltage properties of the output. The output of the power adapter has two types: AC and DC. When purchasing, you should select the voltage type that meets the intended use.
2. Clear signs and complete information. The mark is important information to instruct the user to install and use it correctly, and it is the most basic content to ensure the safety of the user's personal and property. The AC adapter power China sold in my country are required to be marked in simplified Chinese, and at least include the following information: the name, trademark or identification mark of the manufacturer or distributor; model code or model specification; power supply nature; rated power supply voltage range; output voltage range, etc.

3. Pay attention to the rated power supply voltage range. Because the mains voltage in my country is 220V, when purchasing an AC adapter power China, its rated power supply voltage (ie input voltage) range should include 220V, otherwise it will not only not work normally, but may also bring unsafe hazards such as burnout, breakdown and short circuit. .
4. Whether there is a safety certification mark. From design to mass production, AC adapter power China need to go through a series of tests to verify whether they meet the safety requirements. Products that have passed the safety certification test stipulated in my country will be affixed with the "CCC" mark when they are sold.
