Problems solved by technology
[0002] With the advancement of science and technology and the development of battery technology, electric energy is more and more widely used as power. At this stage, power batteries include lead-acid batteries and lithium-ion batteries. As we all know, each battery has its own charging characteristics, so a large amount of charging A device is a device equipped with a charger. Different devices cannot be charged with the same charger. The reason is that different devices use different charging voltages and charging currents (for example, the charging voltages of different models of mobile phones are 4.4V and 5V respectively), that is The charging curve is inconsistent, if forced to charge, it will damage the device
When electronic equipment is eliminated, charging equipment is also eliminated, resulting in a lot of waste
