With the popularization of smart devices, power strips with USB interfaces have become a necessity in home and office scenarios. Among them, 2 gang USB socket and usb double outlet are more favored by overseas users due to their ability to adapt to the charging needs of multiple devices. However, many users encounter overheating during charging, which may hide potential safety hazards. According to monitoring by quality inspection departments, more than 70% of unqualified USB power strips have the risk of overheating and overload, which may cause short circuits or even fires in severe cases. As a manufacturer with more than 40 years of experience in the electrical field, Zhejiang Honghuo Electric combines industry experience to analyze the three core reasons for the overheating of USB power strips, helping users use USB socket and usb outlet more safely.
First, shoddy internal components are the main cause of overheating in low-quality power strips. Whether it is a USB socket or a usb outlet, its core working principle is to convert 220V AC power to 5V DC power through an internal conversion module. High-quality products will use sufficient capacitors, resistors and heat dissipation components, while low-quality products will use substandard electronic components to cut costs. Moreover, the components are arranged too densely, resulting in insufficient heat dissipation space. What's worse, copper-clad aluminum conductors are used instead of pure copper. Aluminum has poor electrical conductivity and is prone to aging and breaking. After being energized, the resistance increases, which will inevitably lead to increased heat generation. Zhejiang Honghuo Electric always adheres to the use of pure copper conductors and flame-retardant engineering plastics, and ensures the rationality of component layout through advanced injection molding machines and assembly lines, eliminating the overheating hidden dangers of USB socket and usb outlet from materials and processes.
Second, overloaded use exceeds the rated load. Most users have the misunderstanding that "more jacks mean you can plug in at will". Especially for USB socket and usb outlet with multiple USB interfaces, if you charge multiple mobile phones and tablets through the USB interface at the same time, and match them with high-power electrical appliances, the total power will easily exceed the rated value of the power strip. When the USB module works at full load or even overload for a long time, the conversion efficiency will drop significantly, and the excess electrical energy will be released in the form of heat energy. The new national standard clearly requires that power strips must be marked with rated power. Users need to confirm that the total load does not exceed the standard before use. The USB socket, usb double outlet and other power strips produced by Honghuo Electric are clearly marked with parameters, and have passed strict load tests to ensure stable work within the rated range. Relevant products have passed multiple authoritative certifications such as CCC and CE.
Finally, improper use environment and product aging. Placing USB socket or usb outlet on flammable surfaces such as carpets and sofas, or using them in high-temperature and humid environments, will hinder heat dissipation and reduce insulation performance; for power strips that have been in service beyond their service life, loose jacks leading to poor contact and aging of internal insulation materials will all cause heat generation. It is recommended that users avoid using power strips in harsh environments, and replace them in time if they find aging signs such as yellowed jacks and loose plugs. The 2 gang USB socket and usb outlet of Honghuo Electric have passed aging resistance and moisture resistance tests, and the shell has passed the 750℃ needle flame retardant test, which can work stably in normal environments, far exceeding the average service life of the industry.
The overheating problem of USB power strips is essentially the result of the combined effect of materials, craftsmanship and usage methods. Since its establishment in 1985, Zhejiang Honghuo Electric has focused on the R&D of European standard electrical products. Its 23,000-square-meter production base is equipped with professional testing equipment. With multiple certification qualifications such as CCEE and ISO9001, it provides safe and reliable switch socket products such as 2 gang USB socket and usb double outlet for global users. It is reminded here that when purchasing, you should recognize regular brands and authoritative certifications, and follow the rated load requirements when using, so as to avoid overheating risks from the source and protect electricity safety.
