Wi-Fi router
Uses 12 W and 100% duty cycle for both stations.
Source-aware comparison
Anker SOLIX C300 vs EcoFlow RIVER 3
A source-backed comparison with neutral, spec-derived verdicts. Unknown fields stay visible, and both stations use the same runtime assumptions.
Compare This Pair For A Real Load
Scenario pages apply one source-backed device load to both stations before you inspect the full table.
Anker SOLIX C300
288 Wh, 300 W AC output.
Confidence: verified. Last verified: 2026-06-24.
EcoFlow RIVER 3
245 Wh, 300 W AC output.
Confidence: verified. Last verified: 2026-06-24.
Capacity
Capacity: C300 is higher by 43 Wh.
AC Output
AC output: both records are equal at 300 W.
Solar Input
Solar input: RIVER 3 is higher by 10 W.
The 60 W runtime estimate assumes AC output, 85% conversion efficiency, and 10% battery reserve. It is a sanity check, not a lab-tested result.
Which one, when?
These verdicts are computed only from tracked specs. They do not use price, affiliate status, ads, sponsorships, or untracked preferences.
Best for longer runtime margin
Anker SOLIX C300 leads this tracked field: 288 Wh vs EcoFlow RIVER 3 at 245 Wh (+43 Wh).
Best for faster solar refill
EcoFlow RIVER 3 leads this tracked field: 110 W vs Anker SOLIX C300 at 100 W (+10 W).
Best for portability
EcoFlow RIVER 3 leads this tracked field: 3.5 kg vs Anker SOLIX C300 at 4.1 kg (+0.6 kg).

Planning Watch-Outs
These checks explain where the comparison is strong and where it still needs better source coverage.
- 5 of 5 high-impact comparison fields are filled on both sides.
- C300 has the larger nominal battery capacity, but usable Wh still depends on reserve, efficiency, temperature, and battery age.
- RIVER 3 is lighter in the tracked weight data, which matters if the station is moved often.
- RIVER 3 has the higher tracked solar input, assuming compatible panels and charge-voltage limits.
