You might think that all electric toothbrush chargers are the same, but that's actually not the case. There are four main types of chargers: standard, USB, inductive, and solar. Standard chargers come with most electric toothbrushes and plug into a traditional outlet. USB chargers are becoming more common and can be plugged into any device with a USB port, such as a computer or laptop. Inductive chargers use magnetic fields to transfer energy, so they're typically more expensive than other types of chargers. Solar chargers are the most eco-friendly option, but they're not as widely available. So, when you're shopping for a new charger, it's important to keep in mind the type of charger that you need.
