Anker SOLIX C800 vs EcoFlow RIVER 2 Pro
Side-by-side on the specs that decide it — surge, capacity, runtime and price.
Both models' specs verified against manufacturer listings · Last updated
The short answer
These two cost the same, so the decision comes down to what you're powering.
- EcoFlow RIVER 2 Pro is 7.9 lb lighter (17 lb vs 24.9 lb).
We'd skip the Anker SOLIX C800 in this matchup. It costs $0 more than the EcoFlow RIVER 2 Pro while matching or trailing it on capacity, surge and cycle life — there's no spec here that justifies the premium.
The C1000's smaller sibling. Same fast-charging DNA at a lower price, but the 768Wh capacity puts it firmly in weekend-trip territory.
Best for: Campers and van-lifers powering electronics, lights and a mini fridge — not home backup.
Where it falls short:
- 300W solar input is low — slow to top off off-grid
- 1600W surge rules out most motor-driven appliances
The one you actually carry. At 17 lb it is light enough for one hand, yet unlike the true pocket units it has the 800W of output needed to run small appliances rather than just charge devices.
Best for: Backpackers, photographers and festival-goers who care about weight above all.
Where it falls short:
- 800W output limits you to electronics and small loads
- 220W solar input means slow off-grid top-ups
