How Much Does It Cost to Run a Wireless Charging Pad?
Formula: `Watts x duty x hours / 1000 x $/kWh = cost`
At $0.15/kWh:
| Usage | kWh per Day | Cost per Day @ $0.15 | Cost per Month @ $0.15 | Cost per Month @ $0.30 |
|---|---|---|---|---|
| 2 hrs/day | 0.030 kWh | $0.004 | $0.13 | $0.27 |
| 4 hrs/day | 0.060 kWh | $0.009 | $0.27 | $0.54 |
| 8 hrs/day | 0.120 kWh | $0.018 | $0.54 | $1.08 |
At California $0.45/kWh, 8 hours a day costs $1.62 per month.
