On paper these two are nearly the same machine: roughly a kilowatt-hour of LiFePO4 battery, an 1800W inverter, a five-year warranty, and street prices that overlap almost completely around $499–$600. That's the honest starting point, and it's why most head-to-heads on this matchup feel padded. The differences that actually matter are narrow and specific: the Anker takes more solar (600W vs 500W) and carries more ports — 11, three of them USB-C — while the EcoFlow can push resistive loads up to 2200W with X-Boost and can grow to 3kWh with add-on batteries. Figure out which of those you'll actually use and the decision makes itself.
The case for the Anker
Anker SOLIX C1000 Editor's Pick
An 1800W, 1056Wh workhorse with 11 ports, fast solar input, and Anker's reliability.

The C1000's pitch is ports and solar. Eleven outputs mean a family's worth of phones, laptops, lights, and a small fridge without an octopus of adapters. The 600W solar ceiling is the sleeper spec: with enough panel it refills from the sun in about 1.8 hours, which turns a weekend off-grid from "ration the battery" into "use it like an outlet." AC charging is quick too — about 80% in 43 minutes, full in under an hour — and the inverter surges to 2400W for startup loads. Two flags. It's around 28 pounds, luggable but not light. And Anker sells a Gen 2 version with 2,000W output and a 4,000-cycle rating alongside the original's 3,000, and listings blur the two constantly — confirm which generation you're buying before you click anything.
The case for the EcoFlow
EcoFlow DELTA 2
A fast-charging 1024Wh station whose X-Boost trick lets it punch above its 1800W rating.

The DELTA 2's signature move is X-Boost: it drives resistive loads — kettles, hair dryers, some space heaters — up to 2200W without tripping, which is exactly the category of appliance that stalls other 1800W stations. Its other real advantage is the upgrade path. Add-on batteries take it to 3kWh, so it can start as a camping box and become a serious blackout kit later without replacing anything. AC charging is genuinely fast (0–80% in about 50 minutes, full in roughly 80), solar tops out at 500W, and the fan gets audible when you work it hard. The 3,000-plus cycle rating trails the newest 4,000-cycle competition, but with LFP chemistry that's still years of regular use.
How to actually choose
Three questions settle it. Will you charge from solar regularly? The Anker's 600W input is the meaningful edge. Will you run heat-making appliances during an outage — kettle, hair dryer, space heater? That's X-Boost territory, and the EcoFlow wins it. Do you expect your needs to grow? Only the EcoFlow has an expansion path; the Anker is what it is on day one.
If none of those apply — you want a solid 1kWh station for occasional outages and car camping — buy whichever is cheaper the day you're shopping. Prices on both move constantly, and at equal money the Anker's extra ports and slightly higher rating (4.7 vs 4.6) make it the default by a hair.
Who should skip both
If your real goal is whole-home backup — furnace blower, well pump, central AC — a 1kWh station is the wrong weight class entirely, and stretching to one of these will only disappoint you. Save for a bigger system. At the other end, if you're only topping up phones and a laptop, both are overkill; a cheap power bank does that job at a tenth the weight.
Bottom line
Two good answers to the same question. Solar-first and port-hungry: Anker. Heating appliances or a growth plan: EcoFlow. No strong pull either way: take the sale price. Just don't pay the Anker's $799 sticker — it routinely sells in the same $499–$600 band as the DELTA 2, and that's the price this whole comparison assumes.
