Solar connection
Not verified
110 W solar ceiling; 11–30 V, 8 A according to the South African table. The connector and exact cable path are not verified here; no panel compatibility is inferred.
USB-C
1 × 100 W
For 12V devices, also verify voltage, polarity, current and fuse—not only the plug shape.

Open manufacturer source ↗Is this model right for me?Uses and regional considerations
Compare your energy and continuous-power target for load shedding; check startup and connections separately.
The South African table lists 600 W surge and 600 W X-Boost with no startup duration; verify appliance startup separately. The same page sells the standard RIVER 3 (under 20 ms) and the 10 ms UPS version, so confirm the UPS variant. On 5 October 2026 the page showed a pre-order notice (shipping 8–9 October).

A fridge cycles on and off. Actual runtime can differ from these continuous-use examples.
300 W continuous; 1 AC outlet (surge and X-Boost 600 W, no duration). AC output voltage and frequency are not stated in the South African table.

Same housing as the standard RIVER 3, so the image cannot distinguish the UPS version. Official EcoFlow South Africa gallery model illustration. Where sockets are visible, the artwork shows South African three-round-pin (Type M-style) and two-pin sockets. Gallery images do not prove the sockets, lead or hardware revision of a delivered unit.

Questions about this model
How much energy does the RIVER 3 (UPS) store?
The manufacturer lists 245 Wh. Conversion loss and a reserve reduce the energy available to your devices.
How much power can it deliver?
Normal continuous output is 300 W. A short surge figure does not prove that every motor or appliance can start.
Which solar panel can I use?
110 W solar ceiling; 11–30 V, 8 A according to the South African table. The connector and exact cable path are not verified here; no panel compatibility is inferred.
