Both are 1,024Wh LiFePO4 stations aimed squarely at the same buyer, so this comes down to whether you value hardware specs or software polish.

The Anker leads on the numbers. It recharges in 49 minutes versus the Delta 2's 80, pushes 2,000W (3,000W surge) versus 1,800W (2,700W), takes 600W of solar versus 500W, and its 4,000-cycle battery outlasts the Delta 2's 3,000 — the spec that most affects long-term value (LiFePO4 vs NMC). On paper, the C1000 Gen 2 is the stronger unit.

The EcoFlow leads on software. Its app is genuinely the best in the category — real-time power-draw monitoring (the easiest way to learn what your gear actually pulls), charge-rate control, and outlet timers. It's also expandable with add-on batteries, where the C1000 is a fixed-capacity unit.
