Yi Nuaner is in a leading position in the domestic low-voltage thermal insulation industry, and its USB electric warm water bag is different from the common plug-in warm water bags on the market, providing consumers with a more convenient and fast choice. Compared with plug-in hot water bags, USB electric warm water bags are mainly powered by low voltage, and the rated voltage generally does not exceed 5V, so there is no need to worry about the risk of electric shock.
 
There are 3 products on sale, among which the F2002 belt warmer provides two heating modes, the first is to install a charging hot water bottle in the belt for heating, and the second is to install a carbon fiber heating element with a USB interface for heating. Different from the hot water bottle, the carbon fiber heating element is lighter in weight and can be carried around, and the USB can be connected to an external mobile power supply for power supply, plug and play, and the 10,000 mAh power bank can be heated for 5 hours normally, which is suitable for people who often travel and travel long distances.
 
The price of Yi Nuaner's USB electric warm water bag is about 80 yuan, which is cost-effective. If you prefer a traditional electric heating water bottle, you can choose Yinuer's nickel alloy heating wire heating water bottle. Although the service life of Yinuer's nickel alloy heating wire is not as good as Mini's carbon fiber heating wire, if used for a long time, the thermal attenuation rate of nickel alloy heating wire is lower than that of carbon fiber heating wire, and the heat transfer effect is more stable.
