quip is powered by the same regular or rechargeable batteries as other electric brushes (AAA in our case). The difference with quip is its removable AAA battery that lasts for over 3 months. Other electrics with locked-in batteries may force you to keep a useless brush even if they stop working, or simply add expense with a separate charging stand. But remember, the efficacy of your toothbrush isn’t defined by power itself, but by how well you follow a proper brushing routine.
