The RIVER 3 is EcoFlow’s entry point: 245 Wh of LiFePO4 rated for 3,000 cycles in a box that weighs under 8 lb. It delivers 300 W continuously, and X‑Boost lets simple resistive devices up to about 600 W run at reduced power.
It refills from the wall in about an hour and takes up to 110 W of solar. It also works as a basic UPS for a router or security cameras. Independent testers measured about 83% efficiency under load, and found it shuts off quickly with anything that pulls more than its rating, such as a full‑size fridge.
Pros
- Very light and compact (under 8 lb)
- Full recharge in about an hour
- LiFePO4 with 3,000 cycles
- App control and IP54 splash resistance
Cons
- Only 300 W, so no fridges, kettles or microwaves
- Just two AC outlets, set close together
- Solar input limited to 110 W
Who it’s for
- Weekend camping and road trips
- Keeping a router and phones online during short outages
- A first power station on a tight budget

What reviewers and owners say
TechRadar praised its size, fast charging and quick UPS switchover, and missed only extra outlets and an LED light. The Solar Lab confirmed the one‑hour recharge and good efficiency, but found X‑Boost struggles with demanding devices like toasters.
