Capacity steps, on the same load

Nominal capacity × depth of discharge × inverter efficiency ÷ sourced average draw.

These are comparison projections, not a promise. Temperature, inverter behavior, cycling, and the individual station's measured delivered capacity can change real runtime.

Personalize the estimate

Use your appliance label or meter

Replace the representative load with a typical-day meter reading. Add the running and startup watts from your own label or meter to update the inverter checks. These entries only change this page view.

Average energy source

Sourced baseline: 46 W average from 46 W running at a 100% duty cycle. Electric cooler (20L thermoelectric) source · 2026-07-20 ↗

Running watts while on (optional)

Blank uses the sourced default. Enter nameplate watts or a meter reading while the compressor or pump is running.

Startup watts (optional)

Leave blank to use a sourced figure when available. Enter real startup watts only from an OEM source or an inrush meter; an LRA amp rating is not a watt value.

Backup window (hours)

Default follows this page's cited use case. Average energy is assumed to continue through this window.

Runtime ladder uses the same comparison assumptions as the table above. Station-specific fit below uses each model's capacity and inverter data.

39 of 80 stations pass the capacity, running, and startup checks for 24 hr using published station specs; appliance startup remains unverified.

Questions, answered from the same inputs

How Many Watts Does an Electric Cooler Use?: Yes. 39 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.
