Rv And Camping
Will a 2000 watt inverter generator run RV AC and microwave?
Use the default WattSizer rule: add running watts, then model the largest startup load while the other selected loads are already running.
A 2,000 W unit is below this conservative estimate.
The peak-starting assumption is driven by 13,500 BTU RV AC. With the default 20% buffer, WattSizer rounds up to the next 100 watts.
| Appliance | Running | Starting | Source note |
|---|---|---|---|
| 13,500 BTU RV AC | 1,600 W | 3,500 W | RV AC manufacturer specs often separate running amps and locked-rotor/start amps; default assumes no soft-start kit. |
| 1,000 W microwave | 1,500 W | 1,500 W | Microwave input watts exceed cooking watts; default uses common nameplate input power. |
| Four phone chargers | 40 W | 40 W | USB charger labels vary; default assumes several fast chargers in use at once. |

Power station estimate
For battery units, the selected running load needs about 0 Wh for 8 hours or 0 Wh for 12 hours before weather, battery age, and inverter losses.
Safety check
Never operate a fuel-burning generator indoors, in a garage, on a porch, or near open windows. Use a listed transfer switch or interlock installed by a qualified electrician for home wiring, and verify actual device nameplates before buying equipment.
Generator or power station?
Fuel generators are useful for motor loads and longer outages, while battery power stations are better for indoor-safe electronics and medical-device planning. For battery sizing, this selected running load is about 30,150 Wh for 8 hours with the same buffer.
