Key specs at a glance

What the numbers mean in practice

  • 286 Wh capacity: a router for about a day, or a CPAP without the humidifier for about one night.
  • 600 W output: covers laptops, fans, a TV and small appliances, not kettles or microwaves.
  • LiFePO4, no published cycle count: EcoFlow states a 10-year lifespan to 80%. See LiFePO4 vs lithium-ion.
  • 10.4 lb: easy to carry one-handed.
  • Expandable to 858 Wh: add an extra battery for longer trips.
  • Warranty: 5 years.

Spec sheets are easy to misread; watts vs watt-hours explains which number answers which question.

Charging speed

About an hour from the wall

The River 3 Plus charges from 0 to 100% in about 1 hour from a wall outlet, at up to 360 W. That's quick enough to top it up before you leave.

Up to 220 W of solar refills it in as little as 1.5 hours.

It accepts up to 220 W of solar at 11–55 V (13 A), and EcoFlow quotes a full charge in as little as 1.5 hours. A car outlet works too. See solar panel sizing.

Capacity and real runtime

Devices and a CPAP, not a fridge

Estimated runtimes on the River 3 Plus

  • CPAP, no humidifier, DC cord7.5 h
  • CPAP with humidifier, AC3.1 h
  • Fridge + Wi-Fi router3.1 h
286 Wh at 85% efficiency for AC and 92% for DC, plus 10 W of inverter draw when AC is on. CPAP 35 W / 70 W; fridge 60 W average; router 12 W on DC.

286 Wh covers a night of devices, lights or a CPAP.

A CPAP without the humidifier runs for about one night on DC. With the humidifier, or with a fridge, expect about 3 hours. For more, see how long a power station runs a CPAP, or try your own devices in the runtime calculator.

Output: what it can and can't run

600 W across seven outlets

Its 600 W covers laptops, monitors, routers, fans, lights, a TV and camera or drone chargers. There are seven outlets: three AC, USB-C, USB-A and a 12 V car socket rated at 126 W.

Three AC outlets, USB-C, USB-A and a 12 V car socket.

X-Boost lets it run heating appliances rated up to 1,200 W at reduced power, so they work more slowly. It won't run a microwave, a coffee maker at full power, or power tools that need a startup surge. EcoFlow doesn't publish a surge rating.

Backup (UPS) and app

Under 10 ms switchover for a router or desk

Plugged into the wall with your devices on its AC outlets, the River 3 Plus switches to battery in under 10 ms when the power drops. That's fast enough to keep most routers and computers on. See using a power station as a UPS.

Noise

Quiet enough for a bedroom

EcoFlow rates the River 3 Plus at under 30 dB, which suits a bedroom or tent at night.

Who should buy it

And who should look elsewhere

Good fit: campers and travellers who want a light station, CPAP users who skip the humidifier, and anyone wanting a quiet battery backup for a router or desk.

Look elsewhere if: you need to run a fridge through an outage or cook. A 1 kWh station such as the Delta 3 or C1000 Gen 2 suits that better.

In our buying guides, the River 3 Plus is best small station in Best Portable Power Station for CPAP and best expandable in Best Small Portable Power Stations.
