BLUETTI AC200P L vs EcoFlow DELTA 3 1500

These are not the same class. One carries noticeably more battery than the other, so this is really a question about how much power you need rather than which brand builds better.

One is a size up

BLUETTI AC200P L holds around a third more battery — 2048Wh against 1536Wh — and that is what decides how long either one lasts on the same load.

BLUETTI AC200P L has the higher ceiling, 2400W, 5 outlets against 3600W (surge 3600W) — enough to matter only if your load list sits right between the two.

EcoFlow DELTA 3 1500 is 26 lb lighter, which at this size is the difference between carrying it and moving it.

BLUETTI AC200P L takes 1200W of solar against 500W, which only matters if a panel is your way back to full — and matters a great deal if it is.

BLUETTI AC200P L refills faster from the wall, accepting 2400W against 1500W.

Drawn from 8 specifications each maker publishes, of which 8 differ. We have not handled either machine — see our methodology.

What the extra battery buys you

Watt-hours are hard to picture, so here is each pack as runtime on the loads a machine this size is usually bought for. Both columns assume 85% inverter efficiency — the conservative end of what these are rated at — so read every figure as a floor.

Load	BLUETTI AC200P L	EcoFlow DELTA 3 1500
Full-size fridge (150W average)	12 hours	8.7 hours
Chest freezer (100W average)	17 hours	13 hours
Gas furnace blower (400W)	4.4 hours	3.3 hours
Sump pump, intermittent (300W average)	5.8 hours	4.4 hours
Space heater on low (750W)	2.3 hours	1.7 hours

From solar alone, at 70% of the panel input each maker quotes — a realistic day rather than a lab figure — the BLUETTI AC200P L needs about 2.4 hours of good sun to refill , and the EcoFlow DELTA 3 1500 about 4.4 hours.

Published by only one of them

A figure missing from a spec sheet is not a zero — it is a number the maker chose not to state. These appear on one page and not the other, so they cannot be compared, only noted.

BLUETTI AC200P L — Cell chemistry: LiFePO4
BLUETTI AC200P L — Cycle life: 3,000+ cycles to 80%
BLUETTI AC200P L — AC outlets: 4 ×120V/20A
BLUETTI AC200P L — Operating temperature: 0°C-40°C / 32°F-104°F
BLUETTI AC200P L — Warranty: 5 Years
EcoFlow DELTA 3 1500 — DC output: 126W max

Where this comparison stops

Everything above is what the makers publish, not what either machine did in front of us. We own neither, so there is no noise measurement, no thermal behaviour under sustained load, and no view on how either holds up after two years. Makers also measure differently — cycle life at 80% capacity is not the same test as cycle life at 70% — so figures that look comparable sometimes are not. Treat this as a way to build a shortlist quickly, and read the caveats on our methodology page before you let a number decide.

Check current prices

Neither figure above is a price. These two move independently and often, and whichever is discounted this week is usually the answer when the specifications are as close as they are here.
