Electric toothbrushes are a relatively new product, and the country has not yet issued any relevant technical standards.So, are wireless chargers for electric toothbrushes universal? What are the technical differences?
1. There are two types of wireless charging protocols for electric toothbrushes:

Qi protocol, proprietary protocols used by electric toothbrush manufacturers
First, let’s talk about the Qi standard, which is supported by virtually all electric toothbrush manufacturers, as well as wireless charger manufacturers. The downside of the Qi standard is that its charging power is relatively low, with a maximum of 10W.
The advantage of a manufacturer’s proprietary protocol is that it can achieve very high wireless charging power. However, if you have a Xiaomi electric toothbrush, for example, you must buy a Xiaomi wireless charger. No third-party manufacturers produce them.
2. How Wireless Charging Works for Electric Toothbrushes:

Electric Toothbrush Inside is a receiver coil made of copper.
The wireless charger contains a copper transmission coil.
When the electric toothbrush is placed on the charger, the transmitter coil generates an electromagnetic field, which the receiver converts into electrical energy for the toothbrush’s battery. This process is called electromagnetic induction.
Because the copper receiver and transmitter coils are very small, wireless charging can only be done at close range.
Summary:Whether wireless charging is compatible with an electric toothbrush depends on the protocol used by the toothbrush.Compatible with international Qi standards,The agreements with electric toothbrush manufacturers are not interchangeable.
