What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
EcoFlow DELTA 2
Only one whitelisted tester, PCWorld, published a hands-on lab review of this exact 1,024Wh Delta 2. PCWorld praised class-leading AC charging, LFP longevity, and modular expansion, but measured a shrill 57dBA fan and roughly 80% usable capacity (dropping to 71% under an 800W load) as real drawbacks. (1 sourced review, 1 lab-tested.)
Praised: Class-leading fast AC charging (~86 min full, up to 1,200W); LFP (lithium iron phosphate) chemistry rated 3,000 cycles for long lifespan; Flexible modular battery expansion up to 2-3kWh.
Flagged: Loud, shrill fans that trigger at anything above 120W (measured 57dBA); Real usable capacity only ~80% of rated, dropping to 71% under heavy 800W load; Extra expansion battery is overpriced.
