Matters needing attention in purchasing USB socket

The charging current and voltage requirements of intelligent devices are different, some are 0.5A, some need 1A, and some need 2A current. When buying USB sockets, please pay special attention to buying products that meet the requirements of conventional smart devices.
2, charging socket compatibility problems
Due to the different charging identification protocols of major mobile phone manufacturers, such as Apple charging head for Samsung mobile phones, the charging speed is very slow or even absent. Most charging socket products in the market only consider the charging agreement of one mobile phone manufacturer when they are designed, and the above-mentioned charging incompatibility may also occur. Therefore, when purchasing products, consumers need to pay attention to whether the smart identification chip is built into the charging socket, because the smart identification chip comes with various mobile phone charging identification protocols, which can simulate the output environment of the original charger and provide safe and fast charging for the mobile phone.
Step 3 choose a brand
Try to buy the products of brand companies, especially those that have passed the national supervision and spot check, and don't buy brands that are repeatedly contacted. Those niche brands that sell at low prices for a long time will inevitably reduce costs and profits, and the safety of sockets will be greatly reduced! Quality brands are safer in terms of quality and safety.
Step 4 find a purchase channel
Unscrupulous sellers mainly use fake goods to mix fake or inferior products into branded products, or keep the panels of branded products and replace them with inferior products. Therefore, when buying switch distribution frames, you can not only identify the brand, but also go to the brand company's specialty stores or designated sales channels to buy them, and save the air tickets so that you can rely on them in future rights protection.
