[PConline News] With the increasing number of smart devices around us, our demand for USB charging is also increasing rapidly, so many traditional white goods and accessories brands have introduced many power strips with USB charging ports. Bring great convenience to our life.
But are these products safe and secure? To this end, the relevant departments conducted random inspections on the market and on the e-commerce platform with a variety of USB-based patch panels to conduct spot checks. The results of random inspections were not optimistic. Only 60% of them were qualified, and Philips went directly to the blacklist...

Sampling involved brands and models are very rich, random inspection results are shown in the following table, click to enlarge, quickly look at the type of your home is not in the table?
According to CCTV's "Weekly Quality Report" report, the inspectors emphasized that the power adapter with a USB interface is not a combination of a USB interface and a patch panel in the ordinary sense. The ordinary plug-in board belongs to the primary circuit, the voltage is 220V, and the other end of the USB interface is directly connected with the mobile phone, belonging to the secondary circuit, and the voltage should be less than or equal to 5V.
The eight unqualified samples tested this time all had the same unqualified items, namely the items of electrical clearance, creepage distance and insulation penetration distance. Experts said that this may lead to users exposed to the high voltage of 220V when using the patch panel to charge the mobile phone.
Even expensive models are on the list
Electricity safety is not a trivial matter, cherish life, and away from poor quality patch panels.
