PCWorld measured 970 Wh and 1,007 Wh of usable AC energy on the BLUETTI AC180. A full-size fridge ran 6 hours on an AC180 with charge still left. An Anker SOLIX C1000 Gen 2 ran a fridge for just under 9 hours.
Estimates use manufacturer specs. We cross-check them against outside measurements where available.
