Frequently asked questions
What can the EcoFlow River 3 power?
Its 245Wh capacity and 300W output suit small loads: a WiFi router and modem, phone charging, and an LED light or two. It works as a desk UPS that switches over in 10ms so your internet never drops. It cannot run a refrigerator or aircon.
How long does the River 3 last?
On a router-and-modem load (roughly 20-30W total) it can keep your internet up for several hours. On heavier draws runtime falls quickly — it is built for essentials during short outages, not overnight backup.
Is the River 3 a good UPS?
Yes, for small setups. Its 10ms switchover is fast enough to keep a desktop, router, and modem running through a power cut without rebooting. For bigger loads or longer runtime, step up to a River 2 Max or a Delta unit.
