Capacity steps, on the same load
Nominal capacity × depth of discharge × inverter efficiency ÷ sourced average draw.
| Capacity class | Estimated runtime | Evidence |
|---|---|---|
| 300 Whstep 1 | 5 hr | Electric cooler (20L thermoelectric) load · 2026-07-20 |
| 500 Whstep 2 | 8.3 hr | Electric cooler (20L thermoelectric) load · 2026-07-20 |
| 1,000 Whstep 3 | 16.6 hr | Electric cooler (20L thermoelectric) load · 2026-07-20 |
| 2,000 Whstep 4 | 33.3 hr | Electric cooler (20L thermoelectric) load · 2026-07-20 |
These are comparison projections, not a promise. Temperature, inverter behavior, cycling, and the individual station's measured delivered capacity can change real runtime.

Questions, answered from the same inputs
- How Many Watts Does an Electric Cooler Use?
- Yes. 38 stations in the current sourced catalog pass the capacity, inverter, and startup checks for the default runtime.
- What power figure matters most for an electric cooler?
- The sourced running draw determines both inverter fit and battery runtime. No separate real-watt startup figure is available from the cited source.
