3 Ways to Cut Your Electric Toothbrush Charger Energy Bill
- 🌱
Unplug the charging base once the toothbrush is fully charged — most hold a charge for 2+ weeks.
- 💡
Charge once a week rather than continuously to avoid trickle-charge energy waste.
- ⚡
Use a smart plug with a timer to power the charger for just 12 hours and then auto-shutoff.
