Are outlet panels with USB charging ports safe?

Conclusion: It depends on the situation.
As long as you choose a regular, quality-assured big brand USB, there is no problem. First of all, most sockets have a voltage of 220V, while USB sockets are weak electronic products with an output voltage of 5V. The USB sockets that meet the standards and are produced by regular manufacturers will have qualified conversion devices. The chip will automatically identify, adjust the output power, automatically distribute the current, and control the output of current and power according to the needs of electronic products without generating excessive power. phenomenon that causes disaster. Moreover, the power output of the USB module is generally between 10 and 20W, and the power itself is not high. Of course, relatively speaking, since it only supports ordinary power and does not support fast charging, the charging speed is limited. If you have higher requirements for charging speed, it is recommended to use the original charging cable + charging head. Secondly, the USB sockets produced by regular manufacturers have charging protection functions, which can automatically cut off the power supply under extreme conditions such as unstable voltage, high temperature, and excessive current to protect the safety of electronic equipment and users. In addition, in general, in the process of manufacturers producing wall power sockets with their own USB charging ports, the feasibility, reliability analysis and testing of the research and development stage, quality control during the production process, and quality inspection before leaving the factory are also essential. of. Therefore, when consumers buy, they must look for regular manufacturers and well-known brands:

1. Check the certification to see that the power strip that has passed the safety certification must have obtained national certification and conform to international industry standards. For the power strip with smart USB charging function, the USB socket part must also meet the national standards and can be sold only after passing the CCC safety certification.

2. Recognize brands as far as possible to buy products from well-known companies, especially products that have passed many national supervision and spot checks, and do not buy brands that have been repeatedly exposed and punished.

3. When choosing a channel, consumers should go to formal large chain supermarkets, hypermarkets or electrical appliance stores to buy power strips, and keep the shopping vouchers, and do not buy low-priced "three noes" in informal stores or street stalls. "product. For online subscription, you need to choose the official platform.

4. When it is sufficient to match the selection, purchase the product with the USB interface and the maximum output current and voltage logo, and confirm whether the maximum output current and voltage match the current and voltage of the charged device. The last thing I need to remind is that it is recommended not to use it while charging, not to use it around flammable items such as bedding, and not to overcharge, long-term power-on, overnight charging, etc. To improve the safety awareness of use, once you find that the USB circuit is abnormal or the charged device is abnormal, please cut off the power of the switch socket immediately. Although big brands have ensured the safety of USB socket panels to the greatest extent, there are still some artificial safety hazards to be avoided. After all, life is your own.
