From the hot water in the hot water bottle to the use of electric heating and then directly to the USB heating. This change has made the winter of the computer family more comfortable.
Recently, when reporters visited the market, they found that many shops have placed USB hand warmer mouse pads and gloves, such as Mickey Mouse, Donald Duck, and Pleasant Goat. According to the merchants, this USB heater is very popular among young people. The girls and students in the office bought the most. Due to the recent rainy weather, USB heaters almost sold out.
This kind of USB heater, because the power supply is through the USB interface, only 5 volts, equivalent to two or three dry batteries, the security is high, 3 minutes can reach more than 30 degrees Celsius in 3 minutes, and then the temperature is maintained at about 45 degrees Celsius. "When using a computer, it is directly connected to the USB interface, and it can be heated in less than a few minutes, which is convenient and cost-effective." Citizen Xiao Chen told reporters that the price of this hand-held mouse pad is generally between 20 yuan and 30 yuan. Left and right, cute shape, easy to use, especially suitable for people who are afraid of cold and love to play computer.
However, some citizens have also reported that some "three no" USB heating products are particularly easy to break and not easy to repair, so you should pay more attention when purchasing USB products. In this regard, the reporter also found that most of these heating products are not packaged, only a simple packaging bag, rarely indicating the manufacturer information, instructions for use and product inspection certificate and other relevant information. According to an industry insider, USB heaters are novel, good sales and easy to copy, so manufacturers are confused and difficult to guarantee quality. As for after-sales service, it is even more difficult to talk about. Therefore, when consumers purchase, they should pay attention to the appearance of the product, and try to choose a regular brand with a fixed brand and a clear manufacturer to ensure the quality.
