The Checks, One by One
| Check | Result | Detail |
|---|---|---|
| Running watts | ✅ pass | 3500W continuous output covers the appliance's 1500W running draw, leaving 2000W of headroom. |
| Runtime | ℹ️ info | 4800Wh of battery at a 75% AC-inverter efficiency factor gives roughly 2.4 hours of continuous running at 1500W. |
Side by Side
| Spec | Renogy Lycan 5000 Power Box | Space Heater needs |
|---|---|---|
| Continuous output | 3500W | 1500W |
| Startup surge | 7000W | No meaningful surge |
| Battery capacity | 4800Wh | — |
| Inverter | Pure sine wave | No waveform requirement |
How Long It Would Run
At a continuous 1500W draw, the Renogy Lycan 5000 Power Box's 4800Wh battery gives roughly 2.4 hours after accounting for a 75% AC-inverter efficiency factor.
A space heater does not draw power continuously — it cycles. At a realistic 80% duty cycle, expect closer to 3 hours of real-world coverage.
About This Appliance
Resistive heating has no startup surge but an enormous sustained draw — this is the fastest way to flatten any battery.

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 site/src/templates/calculator.js DEVICE_LIBRARY (space_heater).
