| 8 hrs/day | 0.320 kWh | $0.048 | $1.44 | $2.88 |
| 24 hrs/day @ 50% | 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 12V Heated Blanket?
No. A 12v heated blanket needs 80W continuous and 0W surge. None of the 0 stations in your file pass – they all fail continuous or surge.
You need at least 96W continuous and 0W surge. A 3000W+ inverter generator is required.
What Size Generator Do You Need for a 12V Heated Blanket?
Minimum 100W continuous, 100W surge. No portable power station in your list passes.
2 Tips to Save Power on a 12V Heated Blanket Only

2. Use low with comforter on top. Low 50W average vs 200W high, same warmth with insulation.
FAQ
Can any power station run a 12v heated blanket?
No station in your file can. Needs 80W continuous, 0W surge. Requires 3000W+ generator.
Do I need pure sine wave for a 12v heated blanket?
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.
