#1 failure reason

57% of the 231 pairings in this category pass our True Surge protocol (SAFE or TIGHT).

Highest surge ratio: 5.26x (Central AC (3-Ton)). Peak power headroom matters more than rated capacity here.
8% of failed pairings could be rescued with a soft-start device, which reduces inrush current by ~55%.
12% of pairings fail on voltage alone. Some devices here need 240V, which most portable stations can't supply.

What matters in this category

AC units have compressor startup surge that can be 3-6x running watts. This is the number one reason portable power stations trip on cooling loads.
Space heaters are predictable (no surge) but draw 1,500W continuously, draining batteries fast.
Central AC units require 240V and draw far more power than any portable station can supply.

How to choose for Heating & Cooling

For AC units, surge capacity is everything. Match the station's peak output to the AC unit's startup surge, not its running watts. A window AC running at 1,000W can spike to 3,000W+ at startup. For space heaters, any station with 1,800W+ continuous output works, but runtime is the real constraint: 1,500W burns through a 2,000Wh battery in about one hour. Box fans are the efficiency play at under 100W.

Common mistake

Choosing a station based on its running watts rating alone. A 2,000W station may not start an 8,000 BTU window AC if it only has 2,400W surge capacity.
