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

A fridge, a TV, phone chargers, and some lights — that's the job description, and it does it fine. It's louder under load than the Honda and the fit-and-finish is a step down, but at this price you can buy one, use it twice a year, and not think about the depreciation.
