Quick answers

Is the EcoFlow RIVER 2 better than the EcoFlow RIVER 3 Plus?

EcoFlow RIVER 3 Plus leads by 15 points overall. No purchase urgency: the performance leader is not at a Good or Great price today.

Which has more usable capacity, the EcoFlow RIVER 2 or EcoFlow RIVER 3 Plus?

The EcoFlow RIVER 3 Plus, by 47 Wh — 196 Wh versus 243 Wh, a 24% advantage. At a 60 W load that is roughly 0.8 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 or EcoFlow RIVER 3 Plus?

The EcoFlow RIVER 3 Plus: 300 W versus 600 W continuous. That gap matters only if a load sits between the two numbers — below 300 W both run it, above 600 W neither does. Surge headroom follows the same order: 600 W against 1,200 W, and surge is what decides whether a compressor or pump actually starts.

How does runtime compare between the EcoFlow RIVER 2 and EcoFlow RIVER 3 Plus?

On the same sourced load — a refrigerator (full-size) — the EcoFlow RIVER 3 Plus runs longer: 3.9 hours against 3.1. 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 or EcoFlow RIVER 3 Plus?

The EcoFlow RIVER 2, by 1.2 kg (3.5 kg versus 4.7 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 3 Plus for home backup; the EcoFlow RIVER 2 for camping & rv. They split, so the honest answer depends on which of those you are actually buying for.

Are the EcoFlow RIVER 2 and EcoFlow RIVER 3 Plus 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.
