What size power station to run a Box fan?

Typical draw: 100W running / 150W starting. Sized below for a 10-hour run — drag the slider for your real runtime. Cheap comfort per watt.

1,176 Wh

1,350 Wh
Look for ≥1,350Wh capacity, ~100W continuous / 150W surge or better.

Right size: Large (≈2,000Wh) · 2,400W

Typical price $1,200-1,900 · e.g. EcoFlow Delta 2 Max, Bluetti AC200L, Jackery Explorer 2000 Plus

A fridge plus several small loads for most of a day, a window AC in short stretches, longer off-grid stays. Heavy to carry but still one-person portable; the point where solar recharge really matters for multi-day use.

Runs this load ~16 h on a full charge.

One size up: Extra-large (≈3,600Wh) · 3,600W

Typical price $2,000-3,200 · e.g. EcoFlow Delta Pro 3, Bluetti AC300 + B300 module

A fridge and essentials for a day or more, a 120V window AC, a home office through a long outage. Approaching generator money; the value comes from pairing it with solar so it refills each day.

Runs this load ~1.1 days on a full charge.

Adjust your loadout and runtime

Real setups aren't one appliance. Add loads and set your runtime below — your Box fan is pre-checked.

Capacity includes inverter loss (~15%) and a usable-charge margin, so the station isn't run flat. A solar panel or vehicle charge extends runtime past this number.
