BLUETTI AC200L vs EcoFlow DELTA 2 Max
BLUETTI AC200L (2,048 Wh, 2,400 W) vs EcoFlow DELTA 2 Max (2,048 Wh, 2,400 W). Their batteries are about the same size, so the differences are in output, charging and features. Here is where each one comes out ahead, based on the manufacturers' published specs.
Each row has its own scale, and the longer bar fills the row. Figures are the manufacturers' published specs.
Choose the AC200L for…
- UPS use: 20 ms switchover (not listed for the other)
- faster solar charging: up to 1,200 W vs 1,000 W of panels
- fast wall charging: 2,400 W vs 1,800 W AC input
Choose the DELTA 2 Max for…
- portability: 12.4 lb lighter (50 lb)

Our verdict
Same 2,048 Wh battery, same 2,400 W continuous and 4,800 W surge. In our calculator they run a typical fridge for the same 30 hours. The differences are charging, expansion and weight, and the AC200L wins two of those three.
The AC200L charges from the wall at up to 2,400 W in its Turbo mode against 1,800 W, takes 1,200 W of solar against 1,000 W, and expands further: up to 8,192 Wh with BLUETTI's batteries, against 6,144 Wh for the DELTA 2 Max. It also has a TT-30 outlet for an RV. BLUETTI lists a 20 ms switchover, while EcoFlow doesn't list one for the DELTA 2 Max.
The DELTA 2 Max is the lighter unit by a lot: 50 lb against 62.4 lb. It has six AC outlets against the AC200L's five.
The bigger issue is availability: when we last checked, the DELTA 2 Max was sold out in EcoFlow's US store, and EcoFlow has replaced it with the DELTA 3 Max. If you find one at a good price with a full warranty, it's still a capable unit. Otherwise the AC200L is the one we'd buy here, as long as you're fine with the weight.
How we compared: the makers' published specs plus our runtime calculations. We haven't bench-tested these units ourselves.
