Our verdict
A small, quick-charging backup for internet gear and phones, with a battery add-on if you outgrow it. For anything above 600 W, step up to a 1 kWh station.
Pros and cons
Pros
- Under 10 ms UPS switchover, quick enough for a router or a desktop PC
- Full recharge from the wall in an hour
- Can grow from 286 Wh to 858 Wh with an add-on battery
- 10.4 lb and small enough for a car footwell
Cons
- 600 W of AC output rules out kettles, hair dryers and most power tools
- Only one USB-C port

The full review
Who it suits
People who want to keep a modem, router and a laptop running through short outages, and campers who need lights and phone charging for a weekend.
Who should skip it
Anyone who expects to run kitchen appliances, power tools or a full-size fridge for long: look at the 1 kWh stations instead.
What we could not confirm
EcoFlow's specification page lists three AC outlets, while the same page's UPS section mentions two rear outlets, so we have left the count out. The warranty term is not stated on the product page; it only links to EcoFlow's warranty policy. EcoFlow's product titles quote 760 W, which is the station's combined output; continuous AC output is 600 W.
Frequently asked questions
- How long does the EcoFlow RIVER 3 Plus take to charge?
- EcoFlow rates it at 0-100% in 60 minutes from a wall outlet and in as little as 1.5 hours from 220 W of solar.
- Can the RIVER 3 Plus run a refrigerator?
- It can power a small fridge that draws less than 600 W, but 286 Wh lasts hours, not a full day. An EB600 extra battery brings it to 858 Wh.
- Is the RIVER 3 Plus a UPS?
- EcoFlow lists a switchover time under 10 ms, which keeps most routers and computers running when the power drops.
