How Much Does It Cost to Run a External SSD?
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 | 0.003 kWh | $0.000 | $0.01 | $0.03 |
| 4 hrs/day | 0.006 kWh | $0.001 | $0.03 | $0.05 |
| 8 hrs/day | 0.012 kWh | $0.002 | $0.05 | $0.11 |
| 24 hrs/day @ 30% | 0.036 kWh | $0.005 | $0.16 | $0.32 |
At California $0.45/kWh, 8 hours a day costs $0.16 per month.
Can a Portable Power Station Run a External SSD?
No. A external ssd needs 5W continuous and 10W surge. None of the 0 stations in your file pass – they all fail continuous or surge.
You need at least 6W continuous and 12W surge. A 3000W+ inverter generator is required.

Minimum 6W continuous, 12W surge. No portable power station in your list passes.
2 Tips to Save Power on a External SSD Only
1. Use eco/low mode. Most external ssd have eco setting that uses 30-50% less watts for same result.
2. Unplug when not in use and clean regularly. Phantom draw 1-3W plus dust adds 5% load.
FAQ
Can any power station run a external ssd?
No station in your file can. Needs 5W continuous, 10W surge. Requires 3000W+ generator.
Do I need pure sine wave for a external ssd?
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.
