| Usage | kWh per Day | Cost per Day @ $0.15 | Cost per Month @ $0.15 | Cost per Month @ $0.30 |
|---|---|---|---|---|
| 2 hrs/day | 0.080 kWh | $0.012 | $0.36 | $0.72 |
| 4 hrs/day | 0.160 kWh | $0.024 | $0.72 | $1.44 |
| 8 hrs/day | 0.320 kWh | $0.048 | $1.44 | $2.88 |
| 24 hrs/day @ 80% | 0.960 kWh | $0.144 | $4.32 | $8.64 |
At California $0.45/kWh, 8 hours a day costs $4.32 per month.
Can a Portable Power Station Run a Phototherapy Light?
No. A phototherapy light needs 50W continuous and 0W surge. None of the 0 stations in your file pass – they all fail continuous or surge.
You need at least 60W continuous and 0W surge. A 3000W+ inverter generator is required.
What Size Generator Do You Need for a Phototherapy Light?
Minimum 62W continuous, 62W surge. No portable power station in your list passes.
2 Tips to Save Power on a Phototherapy Light Only
1. Use dimmer or lower lumens. 10W LED at 50% is still 400 lumens, enough for desk.
2. Use task lighting not room lighting. One 10W desk lamp vs 60W room light saves 83%.
FAQ
Can any power station run a phototherapy light?
No station in your file can. Needs 50W continuous, 0W surge. Requires 3000W+ generator.
Do I need pure sine wave for a phototherapy light?
Yes for electronics and motors. Modified sine wave like MARBERO 88Wh and Azocek 220W causes buzz, heat, and may shorten life. Anker, BLUETTI, EcoFlow, Jackery are pure sine wave.
