Quick answers

Is the EcoFlow RIVER 2 Max 500 better than the EcoFlow RIVER 2 Pro (700)?

EcoFlow RIVER 2 Pro (700) leads by 12 points overall. No price call today — the performance leader has no tracked street price yet.

Which has more usable capacity, the EcoFlow RIVER 2 Max 500 or EcoFlow RIVER 2 Pro (700)?

The EcoFlow RIVER 2 Pro (700), by 156 Wh — 392 Wh versus 548 Wh, a 40% advantage. At a 60 W load that is roughly 2.6 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 EcoFlow RIVER 2 Max 500 or EcoFlow RIVER 2 Pro (700)?

The EcoFlow RIVER 2 Pro (700): 500 W versus 800 W continuous. That gap matters only if a load sits between the two numbers — below 500 W both run it, above 800 W neither does. Surge headroom follows the same order: 1,000 W against 1,600 W, and surge is what decides whether a compressor or pump actually starts.

How does runtime compare between the EcoFlow RIVER 2 Max 500 and EcoFlow RIVER 2 Pro (700)?

On the same sourced load — a refrigerator (full-size) — the EcoFlow RIVER 2 Pro (700) runs longer: 8.7 hours against 6.2. 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 EcoFlow RIVER 2 Max 500 or EcoFlow RIVER 2 Pro (700)?

The EcoFlow RIVER 2 Max 500, by 1.7 kg (6.1 kg versus 7.8 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 EcoFlow RIVER 2 Pro (700) for home backup; the EcoFlow RIVER 2 Max 500 for camping & rv. They split, so the honest answer depends on which of those you are actually buying for.

Are the EcoFlow RIVER 2 Max 500 and EcoFlow RIVER 2 Pro (700) from the same lineup?

Yes — same manufacturer, so warranty terms, app, accessory ecosystem, and expansion batteries are usually shared. That narrows the decision to the hardware differences above rather than to which company you want to buy into.
