What can it actually run?
Checked with the same math as our calculator: total running watts, plus the single largest motor surge on top. “Tight” means it technically fits but the load sits above 80% of rated output — fine briefly, not where you want to live.

The installer's take
3,300W running with a dedicated 30A RV outlet puts this in the same rough bracket as the Predator 3500 above, at 58 lb instead of 99 — wheels and a folding handle make up the difference in easy moves rather than raw carry weight. NOVUS is a newer entrant without the decade-plus track record Honda or Champion have; the CO sensor and triple LED protection (low oil, overload, CO) cover the same safety bases as the established brands, but parts and long-term support are less proven.
Pros
- 3,300W running / 4,125W surge at a sub-$700 price
- 58 lb with wheels — easy to move despite the output
- Dedicated 30A RV outlet (L5-30R) plus two household outlets
Cons
- Newer brand with a much shorter ownership track record than Honda/Champion/Generac
- Recoil start only
