What Size Power Station or Generator Runs a Chest Freezer?
A manual-defrost chest freezer draws 80–165 W when its compressor runs and cycles on about 30% of the day, averaging just 33 W (~800 Wh/day) with a 350–950 W start-up surge.
EcoFlow RIVER 2 Pro
Lowest upfront cost among verified LFP stations that clear the chest freezer's 650W starting surge.
Goal Zero Yeti PRO 4000
Largest LFP battery reserve (3993Wh) for indoor zero-emissions backup.
Westinghouse iGen5000DF
Longest continuous tank endurance with 5000W starting headroom for multi-day grid failures.
