Technical Field

[0001] This utility model relates to the field of battery charging technology, and in particular to a battery charging device. Background Technology

[0002] In modern society, small electronic products are becoming increasingly common, and people's lives are becoming more and more inseparable from them. Examples include power banks, flashlights, razors, hair clippers, and electric toothbrushes—small electronic products powered by single or multiple lithium batteries. Using rechargeable batteries, which separate the battery from the electronic product, allows users to better observe and even detect whether the battery is leaking, bulging, corroded, etc., thus reducing the possibility of fires and personal injury caused by short circuits in electronic products. However, most existing charging devices use plug-and-play charging cables, requiring users to adjust the orientation and pair the devices, and also preventing the simultaneous charging of multiple batteries.
