How Much Does It Cost to Run a Electric Toothbrush Charger in Australia? (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 A$0.000 per hour, or about A$0.25 per month at 24 hours a day in Australia. Cheap to run
| Wattage | Per hour | Per day | Per month | Per year |
|---|---|---|---|---|
| Low (0 W) | A$0.000 | A$0.004 | A$0.13 | A$1.53 |
| Typical (1 W) | A$0.000 | A$0.008 | A$0.25 | A$3.07 |
| High (2 W) | A$0.001 | A$0.017 | A$0.50 | A$6.13 |
Formula: watts ÷ 1000 × hours × price per kWh. Typical use is 24 h/day ≈ 9 kWh per year.
In Australia, with electricity at A$0.35 per kWh (source: AER Default Market Offer 2026–27, 2026-07), a typical electric toothbrush charger costs A$0.000 per hour and about A$3.07 per year at 24 hours a day. Each A$1.00 of electricity buys roughly 2,857.1 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 (A$1.53) per year if it is never unplugged.
