EcoFlow RIVER 3

The RIVER 3 in brief

A rated 3,000 cycles to 80 percent puts the RIVER 3 third on cycle life among the 13 stations under 300 Wh, which counts for a lot in a small box. It holds 245 Wh in LFP cells and weighs 7.72 lb. The AC outlets give 300 W, with 600 W available for a moment, and USB-C output reaches 100 W. A wall plug refills it in 0.8 hours at 320 W. Solar goes in through an XT60i port with a 110 W limit. This is a phone, laptop and router unit first, and a small cooler or camp light unit second. Anything that heats, pumps or needs a hard start from a compressor is out of its range.

How long the RIVER 3 runs things

Times use about 85% of the rated capacity, the part left after inverter and battery losses. The usable estimate is 208 Wh and the AC side stops at 300 W, so a 192 W chest freezer gets 5.3 h to 9.1 h while an 875 W furnace blower is past its limit.

Work out your own mix of loads. A red bar means it draws more than the 300 W this station can supply.

How fast it refills

Solar time assumes panels reach 75% of their rating. Figure it for your state and panels.

Solar panels for the RIVER 3

Its XT60i port takes 11 to 30 V, up to 8 A and 110 W. A panel's voltage rises in the cold, so the marks below show each one at 14 F, and a pass here keeps 10% of headroom under the maximum.

FAQ

Can the EcoFlow RIVER 3 run a refrigerator?

A refrigerator drawing 104 W is inside its 300 W output and runs for 2.3 h to 6 h. Its startup draw of 1305 W is above the 600 W the RIVER 3 can briefly deliver, so the fridge's start is the part that decides it.

How long does the RIVER 3 take to charge?

From a wall outlet it takes 0.8 hours. A car's 12 V socket takes 2.6 hours, and solar at the full 110 W input takes 3 hours.

Which solar panels work with the RIVER 3?

Its input window is 11 V to 30 V at up to 8 A, and every EcoFlow portable panel listed, from the 100W Rigid to the NextGen 220W, sits inside that. Only one panel can go in at a time, and each needs an MC4 to XT60i cable.

Does the RIVER 3 work in cold weather?

EcoFlow lists an operating range of 14 F to 113 F.
