What it is

US SKU ZMR330-US on EcoFlow’s DELTA 2 page: portable power station with ~1,024 Wh LFP pack and 1,800 W continuous AC inverter. Manufacturer also lists X-Boost up to 2,200 W and surge around 2,700 W — those are not the overnight continuous budget. Desk review of manufacturer claims — not a cycle-life bench. Outage Stack planning assumption (not manufacturer): usable Wh = rated Wh × 0.85. At a 500 W load: 1,024 × 0.85 ÷ 500 ≈ 1.7 h.

Verdict

Buy for quiet 1.8 kW / ~1 kWh portable LFP essentials when you accept recharge logistics. Skip if you needed DELTA Pro 3-class watts/Wh or believed X-Boost was continuous.
