Where these rank

Quick answers

Is the Anker SOLIX C800 X better than the EcoFlow RIVER 2 Pro (700)?
Too close to call overall — choose by how and where you use it. No price tie-breaker today — choose based on fit and the sourced details.
Which has more usable capacity, the Anker SOLIX C800 X or EcoFlow RIVER 2 Pro (700)?
The Anker SOLIX C800 X, by 32 Wh — 580 Wh versus 548 Wh, a 6% advantage. At a 60 W load that is roughly 0.5 extra hours before the battery is empty. Both figures are estimated AC-delivered energy, not the nameplate battery rating — the watt-hours that actually reach your devices, which is always less than the number on the box.
Which has more AC output, the Anker SOLIX C800 X or EcoFlow RIVER 2 Pro (700)?
The Anker SOLIX C800 X: 1,200 W versus 800 W continuous. That gap matters only if a load sits between the two numbers — below 800 W both run it, above 1,200 W neither does. Surge headroom follows the same order: 1,600 W against 1,600 W, and surge is what decides whether a compressor or pump actually starts.
How does runtime compare between the Anker SOLIX C800 X and EcoFlow RIVER 2 Pro (700)?
On the same sourced load — a refrigerator (full-size) — the Anker SOLIX C800 X runs longer: 9.2 hours against 8.7. These are planning estimates from each model's AC-delivered capacity, not stopwatch tests; real duty cycle and temperature move them.
Which is lighter, the Anker SOLIX C800 X or EcoFlow RIVER 2 Pro (700)?
The EcoFlow RIVER 2 Pro (700), by 3.1 kg (7.8 kg versus 10.9 kg). Both weights are manufacturer figures for the bare unit; cables and a solar panel add to whatever you actually carry.
Which model should I buy for my use case?
On the sub-scores that describe each use case: the Anker SOLIX C800 X for home backup; the EcoFlow RIVER 2 Pro (700) for camping & rv. They split, so the honest answer depends on which of those you are actually buying for.
