Put these two side by side and you're looking at nearly the same machine: about a kilowatt-hour of LiFePO4 battery, 1800W of AC output, a wall recharge measured in minutes rather than hours, and support for an add-on battery when the base capacity stops being enough. Either one will carry a fridge, a CPAP, laptops, lights, and a coffee maker through an outage. So the question isn't which one is good — it's which small differences you'd actually feel.
Here's the honest gap. The Anker has the better paper case: cells rated for 4000+ cycles against the EcoFlow's 3000+, a five-year warranty, 600W of solar input versus 500W, a full recharge in roughly 58 minutes, and sale prices that regularly drop into the $399–$499 range — usually a solid step below where the DELTA 2 lands even on discount. The EcoFlow answers with a higher surge rating (2700W X-Boost against the Anker's 2400W peak), a stated expansion path to 2048Wh, and a bigger, more mature accessory ecosystem. None of these differences is huge. All of them are real.

How to actually choose
Start with price on the day you're buying, because it moves the most. The C1000 lists at $599–$799 and the DELTA 2 at $649–$999, but both go on sale constantly, and the sale price is the real price. If the Anker is sitting near $400 while the EcoFlow is at $550, that difference buys a lot of solar panel — and neither unit includes panels, so budget for those separately if off-grid charging is the point.
If prices land close, think about what you'll plug in. The DELTA 2's 2700W surge gives it more headroom for motor-driven loads — the compressor kick of a fridge, a power tool spinning up — the kind of margin you don't notice until the one moment it matters. If your outage plan includes anything with a motor bigger than a refrigerator's, that's the EcoFlow's best argument.
The cycle-life gap sounds dramatic — 4000+ versus 3000+ — but be realistic. Even cycling the battery every other day, either unit will outlast most people's interest in owning it. The Anker's five-year warranty is the more practical edge, because it covers the years you'll actually use the thing. The soft points cut both ways too: the Anker's display and app are more utilitarian than some rivals', and the EcoFlow's fan gets audible under heavy load or fast charging — worth knowing if it'll sit in a bedroom during a blackout.
Who should skip both
If you mostly car-camp and charge phones, both are overkill. These are mid-20s-of-pounds boxes, not grab-and-go bricks, and a small 300Wh station does that job for a fraction of the money. At the other end, if you're trying to back up a well pump, central air, or an electric range, an 1800W unit with a kilowatt-hour of storage isn't the tool — you're shopping the wrong class entirely, and no amount of comparing these two fixes that.
Bottom line
The ratings are a wash — 4.7 versus 4.6 — and neither is a mistake. Buy the Anker SOLIX C1000 if you can catch it on sale: more rated cycles, longer warranty, more solar input, less money. Buy the EcoFlow DELTA 2 if you want the surge headroom for motor loads or you plan to grow into EcoFlow's batteries and panels later. And if both are sitting at full list price, wait — one of them almost always drops within the week.
