How Much Does It Cost to Run a USB Charging Hub?
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 | 0.060 kWh | $0.009 | $0.27 | $0.54 |
| 4 hrs/day | 0.120 kWh | $0.018 | $0.54 | $1.08 |
| 8 hrs/day | 0.240 kWh | $0.036 | $1.08 | $2.16 |
At California $0.45/kWh, 8 hours a day costs $3.24 per month.
