The Phillips Sonicare electric toothbrush is really common. Or at least, in my country. This works with any of their models. It stays charged for about two months or so, depending on long you charge it. I think mine is called a C2 model (the cheapest one). As I said, they are everywhere. You can buy one on Amazon, Target, Walmart, Bestbuy, and Costco. So, when it dies instead of charging it for hours, you can charge it for only 30 seconds or so! The toothbrush only wants to work went it has a certain amount of charge. Even though it has enough to work. If you put your toothbrush on the charger for about 30 seconds it will work! Try it out! Sorry if I am not explaining this well. This also works with Oral B toothbrushes and probably most toothbrushes. At the top, there is a picture of my toothbrush. The Sonicare ones also have a two-minute timer. So here’s a recap... Do you know how you wait for hours for your toothbrush to charge? You can only charge it for 30 seconds and it will work!
