How Much Does It Cost to Run a Electric Toothbrush Charger in Ontario? (2026)
An electric toothbrush charger draws about a watt whether or not the brush is on it. Over a year that is under 10 kWh, one of the smallest loads in the house.
A typical electric toothbrush charger (1 W) costs C$0.000 per hour, or about C$0.11 per month at 24 hours a day in Ontario. Cheap to run
| Wattage | Per hour | Per day | Per month | Per year |
|---|---|---|---|---|
| Low (0 W) | C$0.000 | C$0.002 | C$0.054 | C$0.66 |
| Typical (1 W) | C$0.000 | C$0.004 | C$0.11 | C$1.31 |
| High (2 W) | C$0.000 | C$0.007 | C$0.22 | C$2.63 |
Formula: watts ÷ 1000 × hours × price per kWh. Typical use is 24 h/day ≈ 9 kWh per year.

In Ontario, with electricity at C$0.15 per kWh (source: Hydro-Québec 2025 comparison, 2025-04), a typical electric toothbrush charger costs C$0.000 per hour and about C$1.31 per year at 24 hours a day. That is about 7% more than the national average for Canada (C$0.10 per month), because electricity in Ontario costs C$0.15 per kWh against C$0.14 nationally. Each C$1.00 of electricity buys roughly 6,666.7 hours of use.
How to lower the cost of running a electric toothbrush charger
- Unplug the charger when the brush is fully charged if you want to eliminate the last watt.
- Charge every few days rather than leaving it docked constantly to extend battery life.
- Nothing else. This is not where savings are.
In standby it draws about 0.5 W, which adds roughly 4 kWh (C$0.66) per year if it is never unplugged.
