Who should buy which
Best all-round value
Winner: Anker C1000
Lower price, faster headline recharge, a higher 3,000W peak for startup loads, and one of the largest, strongest review bases in the class. For a first home-backup station it’s the easy pick.

Winner: EcoFlow DELTA 3 Plus
If you want to grow capacity for long outages, the DELTA 3 Plus scales to ~5,120Wh with add-on batteries — more total headroom than the C1000’s single expansion battery. For serious hurricane-season backup, that ceiling matters.
Check DELTA 3 Plus price →Fast top-ups between outages
Winner: tie
Both recharge in roughly 45–56 minutes on AC — genuinely class-leading. The Anker’s ~49-minute figure edges the headline, but in real use you won’t notice the difference. Pick on price and expandability instead.

Winner: Anker C1000 (verified)
The C1000 takes up to 600W of solar and tops up in about 1.8 hours of good sun — a figure we can confirm from its listing. The DELTA 3 Plus also charges from solar; check its live listing for the exact input before pairing panels.

- Buy the Anker SOLIX C1000 Gen 2 if you want the best value: lower price (~$599), ~49-minute recharge, 3,000W peak, 600W solar input, and a proven 4.7/5 track record. For most homes this is the one.
- Buy the EcoFlow DELTA 3 Plus if expandability is the priority — scaling to ~5,120Wh makes it the stronger base for multi-day outages — or you already run EcoFlow gear.
- Either way, these are backup power stations, not grid-tie solar. If your goal is shaving your daily electricity bill rather than outage backup, a balcony solar kit is the better spend.

FAQ
- Which is better value, the Anker SOLIX C1000 or the EcoFlow DELTA 3 Plus?
- For most U.S. buyers the Anker SOLIX C1000 Gen 2 is the better value: it typically costs less (around $599 vs roughly $829–899 for the DELTA 3 Plus), recharges to 100% in about 49 minutes, delivers 2,000W (3,000W peak), and has a very large, strong review base (4.7/5 across 1,300+ ratings). Choose the EcoFlow DELTA 3 Plus if you want maximum future expandability — it scales to about 5,120Wh with extra batteries — or you are already in the EcoFlow ecosystem.
- Do they have the same battery size?
- Their core capacity is nearly identical: both use roughly a 1,024Wh LiFePO4 battery. They differ on output — the Anker C1000 Gen 2 is rated 2,000W with a 3,000W peak, while the EcoFlow DELTA 3 Plus is rated 1,800W AC with a 3,600W X-Boost surge — and on how far each expands with add-on batteries.
- Which one charges faster?
- Both are class-leading. The Anker SOLIX C1000 Gen 2 reaches 100% in about 49 minutes on AC (up to 1,600W input). EcoFlow lists the DELTA 3 Plus at roughly 43–56 minutes wall-to-full. In practice they are very close; the Anker edges it on the headline figure.
- Can I expand the capacity for multi-day backup?
- Yes for both, which matters for hurricane season. The EcoFlow DELTA 3 Plus expands to about 5,120Wh with optional extra batteries. The Anker SOLIX C1000 accepts an add-on expansion battery to increase runtime. Both can also recharge from solar — the Anker C1000 takes up to 600W of solar input.
