Best power station for a window AC (5,000 BTU)
A window AC (5,000 BTU) draws about 450W while running and up to 1300W for a moment at startup, averaging 315W because it cycles on and off. Small window units draw around 450W while the compressor runs. On hot days it rarely switches off, so expect 60–80% duty.
