≈ 1.7 days (24h/day) · Safe motor start buffer (86.5% margin).
chest freezer running (165 W max) and start-up (950 W max) draw fit the EcoFlow DELTA 2 Max's 2,400 W continuous / 4,800 W surge ratings.
5–7 cu ft chest freezer with lid kept closed (~29% duty cycle, 23 W avg)
10–15 cu ft chest freezer at ~30% compressor duty cycle (33 W avg)
16–22 cu ft chest freezer or warm garage ambient (~32% duty cycle, 52 W avg)
≈ 1.7 days (24h/day)
System standby power: 15W (29.4% of total draw)
Provides 6× CEE 7/3 (230V) (120V 60Hz).
Pure sine wave inverter output. Safe for all standard household appliances.
Inductive motor/compressor load with 5.7× starting surge (motor inrush) (86.5% worst-case surge margin).
Wall AC fast charge at up to 1800W (66m to 80%, 80m to 100%).
Safe envelope verified: Starting surge (650W) remains comfortably below the 4800W surge trip line, with steady-state operation settling into the safe continuous zone at 115W.
About 40 hours on AC power, with the chest freezer averaging 33 W (10–15 cu ft chest freezer at ~30% compressor duty cycle (33 W avg)). The EcoFlow DELTA 2 Max then draws about 51 W from its battery, including 15 W for the inverter itself. Best case: about 51 hours (5–7 cu ft chest freezer with lid kept closed (~29% duty cycle, 23 W avg)). Worst case: about 29 hours (16–22 cu ft chest freezer or warm garage ambient (~32% duty cycle, 52 W avg)).
Yes. The chest freezer's start-up peak of about 650 W (up to 950 W) fits within the EcoFlow DELTA 2 Max's 4,800 W surge rating, with 80% headroom even in the worst case.
That simple division gives 61 hours, but the EcoFlow DELTA 2 Max's inverter draws about 15 W whenever its AC outlets are on. At this light load that's 29% of everything the battery supplies, and inverter conversion losses take a further share. EcoFlow doesn't publish an idle figure and we haven't found an independent measurement, so this uses our 15 W estimate.
On wall power: about 66 minutes to 80% and 80 minutes to full (EcoFlow figures). With its maximum 1,000 W of solar input connected, expect about 800 W in full sun, so a full recharge takes roughly 2.7 hours of full sun, so it can refill in a single day with 4 peak sun hours.
