How Much Does It Cost to Run an Electric Scooter Charger in Hawaii? (2026)
An electric scooter battery holds 250 to 600 watt-hours. A full charge costs a few cents and takes 3 to 6 hours, making a scooter about the cheapest motorised transport there is.
A typical electric scooter charger (80 W) costs $0.042 per hour, or about $5.06 per month at 4 hours a day in Hawaii. Cheap to run
| Wattage | Per hour | Per day | Per month | Per year |
|---|---|---|---|---|
| Low 40 W | $0.021 | $0.17 | $5.06 | $61.58 |
| Typical 80 W | $0.042 | $0.17 | $5.06 | $61.58 |
| High 150 W | $0.079 | $0.17 | $5.06 | $61.58 |
Formula: watts ÷ 1000 × hours × price per kWh. Typical use is 4 h/day ≈ 117 kWh per year. A more powerful model does the same job faster, so it uses the same energy: the cost per hour changes from row to row, the cost per day does not.
One day of an electric scooter charger (1.9 kWh) is the same electricity as
- 11km in an electric car
- 19hours of TV
- 43hours of a laptop
- 213hours of an LED bulb
In Hawaii, with electricity at 52.7¢ per kWh (source: EIA Table 5.6.A, 2026-06), a typical electric scooter charger costs $0.042 per hour and about $61.58 per year at 4 hours a day. That is about 187% more than the national average for the US ($1.76 per month), because electricity in Hawaii costs 52.7¢ per kWh against 18.3¢ nationally. Each $1.00 of electricity buys roughly 23.7 hours of use.
How to lower the cost of running an electric scooter charger
- Charge at room temperature. Cold batteries charge slowly.
- Unplug at 100 percent. Most chargers draw a watt or two indefinitely.
- Keep tyres inflated. Low pressure can cut range by 10 to 20 percent.
In standby it draws about 1 W, which adds roughly 9 kWh ($4.62) per year if it is never unplugged.
