What reviewers say

EcoFlow RIVER 3 Plus

Owners of the RIVER 3 Plus generally rate it well for its fast recharge, quiet operation and compact size. Complaints center on the modest 600W ceiling and the cost of the expansion battery.

What people mention
  • Output powerMixedReviewers like the 1200W X-Boost for short surges but note 600W continuous won't run kettles or heaters.
  • Recharge speedPraisedOwners report roughly an hour to full from a wall outlet, which they call a standout.
  • BatteryPraisedThe LiFePO4 cells are cited for long cycle life and safety versus older lithium packs.
  • PortabilityPraisedAt 4.7 kg and under a foot wide, owners carry it between rooms and campsites easily.

Questions and answers

Which one can run a mini fridge?
The EcoFlow RIVER 3 Plus. Its 600W rated output and 1200W X-Boost cover most mini fridges, while the Weekender's 250W continuous output will trip on startup surge.
Which is better for camping?
The Weekender MAX PRO is lighter at 5.6 lb and comes as a solar kit, so it suits tent camping and phone charging. The RIVER 3 Plus is better if you also want to run a camp stove or cooler.
Which battery lasts longer?
The RIVER 3 Plus. LiFePO4 chemistry typically delivers several thousand cycles, well beyond the lithium-ion polymer cell in the Weekender.
Is the EcoFlow worth the extra money?
If you need appliance-level power, UPS backup or expansion to 858Wh, yes. If you only charge phones and laptops on trips, the lighter Weekender covers that for less.
Can the Weekender run a laptop?
Yes. Its USB-C PD 60W port and pure sine wave AC output handle most laptops, and 277.5Wh gives roughly several charges depending on the laptop.
Does the RIVER 3 Plus work as a UPS?
Yes. It switches to battery in under 10 ms, which keeps desktops and precision devices running through short outages.
