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.
Anker SOLIX C1000
Only one whitelisted tester — TechRadar — published a genuine hands-on review of the original Anker SOLIX C1000; it rates the unit 'reliable and robust' with excellent ports, Wi-Fi/Bluetooth app control, and real-world outage use, faulting only premium pricing. Notebookcheck and others reviewed the Gen 2 or C1000X, not this exact model, so were excluded. (1 sourced review.)
Praised: Excellent port selection and output options; Reliable, durable Anker build quality; Wi-Fi and Bluetooth remote control via the Anker app.
Flagged: Premium pricing.
