Our verdict
The BLUETTI AC180 gives you slightly more capacity (1,152 vs 1,024 Wh) and the same 1,800 W continuous output for a much lower list price ($499 vs $799). The EcoFlow DELTA 3 Plus earns its premium with features: a 3,600 W surge rating (vs 2,700 W), 1,000 W of solar input (vs 500 W), a 56-minute wall charge, 4,000 rated cycles (vs 3,500), six AC outlets (vs four), expansion to about 5 kWh, and it’s 7.7 lb lighter.
If you want a capable 1 kWh backup for the least money, the AC180 is hard to beat. If you’ll use solar, want to expand later or carry it around, the DELTA 3 Plus is worth the extra cost.
