How to choose

TT-30R outlet

Many models in this class add a TT-30R RV outlet. Check for it if you camp.

Mistakes to avoid

  • Assuming 240 V: most 3,500 W units are 120 V only.

Frequently asked questions

What will a 3500 watt generator run?

An RV with one 13,500 BTU AC, or a fridge, freezer, sump pump and lights at home (not all starting at once).

Will a 3500 watt generator run a house?

Only the essentials through extension cords. For hardwired circuits and a well pump, you need more power and 240 V.

Is a 3500 watt generator enough for a 30 amp RV?

Yes for most 30 A rigs with one AC, managing other loads while the AC runs.
