Anker vs EcoFlow power stations

Does EcoFlow undercut Anker at 288 Wh?

Yes on the list price we checked, by about $131. The RIVER 3 Plus also doubles continuous watts (600 W vs 300 W) and prints 3,000 cycles to 80%; the C300 is about a pound lighter with a bare 3,000 on the cycle line. Same watt-hours, both UPS under 10 ms — the price and the finish percent are the fork, not the chemistry.

A laptop and lights stay inside 300 W, so the lighter C300 is what you feel in the hand. Need closer to 600 W, or a second battery later, and open the RIVER 3 Plus.

Anker SOLIX C1000 Gen 2 or EcoFlow DELTA 3?

Same 1,024 Wh. If the box has to ride in the trunk, the Anker SOLIX C1000 Gen 2ModelAnker SOLIX C1000 Gen 28.8 / 101,024 Wh · 2,000 W · 24.9 lb · 11.29 kg · $699.99 lists 2,000 W continuous, 24.9 lb, UPS under 10 ms, solar up to 600 W, and a bare 4,000 cycles, at $699.99 on 2026-10-31. The EcoFlow DELTA 3ModelEcoFlow DELTA 38.8 / 101,024 Wh · 1,800 W · 27.6 lb · 12.52 kg · $629.00 lists 1,800 W, 27.6 lb, UPS under 10 ms, solar up to 500 W, an add-on battery, and 4,000 cycles to 80%, at $629 the same day — about $71 less.

OutdoorGearLab usable AC sits close: about 890 Wh on the Gen 2 and about 870 Wh on the DELTA 3. That is not what separates them. Continuous watts do — and OutdoorGearLab lists 1,800 W AC for the Gen 2 while Anker prints 2,000 W, so treat the higher ceiling as a brand claim on the model page. Gen 2 does not take an extra battery; DELTA 3 does if you buy one.

Is EcoFlow cheaper than Anker near 2,000 Wh?

These stay on the floor. For a power cut at home — fridge, router, lights — yes, about $450 less on the list price we recorded. The Anker SOLIX C2000 Gen 2ModelAnker SOLIX C2000 Gen 29.0 / 102,048 Wh · 2,400 W · 41.7 lb · 18.91 kg · $1,199.99 and the EcoFlow DELTA 3 MaxModelEcoFlow DELTA 3 Max9.1 / 102,048 Wh · 2,400 W · 44.8 lb · 20.32 kg · $749.00 both sit at 2,048 Wh and 2,400 W continuous. C2000 Gen 2 lists 41.7 lb, solar up to 800 W, and an add-on battery, at $1,199.99 (2026-11-01); UPS time in milliseconds and cycle life are blank on our page. DELTA 3 Max lists 44.8 lb, UPS under 10 ms, and solar up to 500 W, at $749 (2026-10-31); cycle life blank, and no second battery on our page.

EcoFlow takes the list price and a printed UPS time. Anker keeps about three fewer pounds, more solar input, and room for a second battery. Both leave cycle life unfinished here.

We looked at capacity and continuous output. A UPS time appears only when the brand lists one. review.

What should I check before I buy?

• Similar watt-hours. Put C300 next to RIVER 3 Plus, or Gen 2 next to DELTA 3 — not a 288 Wh box next to a 2,000 Wh unit.
• Continuous watts, list price, and a second battery. Anker often prints more AC watts; EcoFlow often undercuts on price or lists an add-on battery.
• Cycle percent and UPS time. Prefer a finish percent beside the cycle count. A blank on our page is missing data — not the same as “no.”
