The Checks, One by One
| Check | Result | Detail |
|---|---|---|
| Running watts | ✅ pass | 2400W continuous output covers the appliance's 1800W running draw, leaving 600W of headroom. |
| Runtime | ℹ️ info | 2048Wh of battery at a 75% AC-inverter efficiency factor gives roughly 0.9 hours of continuous running at 1800W. |

How Long It Would Run
At a continuous 1800W draw, the EcoFlow DELTA 3 Max's 2048Wh battery gives roughly 0.9 hours after accounting for a 75% AC-inverter efficiency factor.
About This Appliance
Dominated by the heating element, so there is no meaningful startup surge. The low heat setting roughly halves the draw and is what makes this runnable on midsize units at all.

Methodology
Verdict computed from this project's verified entity data using the same gates as its use-case scoring: waveform requirement first (an unconfirmed inverter type fails rather than passing), then continuous watts, then startup surge, then runtime at a 75% AC-inverter efficiency factor. Entity specs verified 2026-09-13; appliance figure from content/guides/can-power-station-run-hair-dryer.json (1,200-1,800W on high heat; US models are commonly rated to a 1,875W maximum), sourced there from eia.gov residential electricity use.
