Battery & slim electric toothbrushes

4 models · 3 brands, ~$16–$40

These are the brushes built around never needing a charger: a single AAA that the maker says lasts up to three months, or a slim rechargeable with a month or more between charges. They are light, cheap and easy to travel with, and they give up pressure sensors, modes and screens to get there.

Ordered by price, lowest first.
