EcoFlow RIVER 3 review
Updated October 8, 2026
The RIVER 3 is a small camping station with 245Wh and 300W continuous. Capacity is 11Wh below the 256Wh model it follows. The change is a LiFePO4 pack, a wall charge of about an hour, and a UPS switch under 20 ms. It weighs 7.8 lb.
How Pack Current compares stations: the maker's published spec sheet, the live amazon.com listing, and recurring points in owner reviews (real solar input, fan noise, carry weight). Runtimes are calculated from watt-hours, with the math shown. How we compare.

What the numbers mean
Capacity is 245 Wh. That is enough for phones, lights, and a laptop on a short trip — not a fridge overnight. Treat “days of phone charge” on the carton as marketing until the load is named.
Continuous output is 300 W. That is the limit for what you can plug in at once. Surge is listed at 600 W, with a boost/lifting figure of 600 W on some sheets. A fridge start-up can exceed continuous watts even when the watt-hour number looks fine.
Weight is 7.8 lb (3.5 kg). Light enough to take from the car to camp without making the station the heaviest thing in the kit. Solar input is listed at 110 W. Wall charge is usually faster than a folding panel in real sun.
Carton runtime claims stay marketing until the load is named. How we compare.
Outlets
2× AC (300W total), 1× 100W USB-C, 2× 12W USB-A, 1× 12V car (126W).
Inverter waveform on the published sheet: pure sine. Chemistry: LiFePO4.
Skip if
Skip it if you need a compressor fridge overnight. At 245Wh that job runs out. Skip it also if you only need to top up a phone. A power bank is lighter than 7.8 lb.
Good for a camping weekend.

Common questions
- How long will the EcoFlow RIVER 3 run a 12V fridge?
- A 12V compressor fridge often averages about 50W while it cycles. Usable capacity is about 208Wh, from 245Wh times 0.85. At 50W that is about 4 hours. At 60W the same math is about 3 hours. At 40W it is about 5 hours. Heat, duty cycle, and inverter idle draw move the result.
- Can the EcoFlow RIVER 3 run a coffee maker or microwave?
- A drip coffee maker is often 800–1,200W. A microwave is often 1,000–1,200W at the wall. The EcoFlow RIVER 3 is rated 300W continuous. That is below those loads.
- How fast does the EcoFlow RIVER 3 recharge from solar?
- In ideal sun, 245Wh divided by 110W of solar input is about 2.2 hours. That figure is an ideal-sun floor. Real panels deliver less than their rated watts once heat, cloud, and a low sun angle are in the picture.
- How heavy is the EcoFlow RIVER 3?
- The EcoFlow RIVER 3 weighs 7.8 lb. One person can carry it from the car to camp.
