Data from official source
EcoFlow RIVER 3 Plus Wireless is an ultraportable lithium iron phosphate power station with a magnetic power bank attached to the lid: a phone rests there and charges, and the power bank detaches and goes in a pocket while the power station stays put, still working.
There are three AC outlets, which on a unit this size means not having to carry a power strip along. Connected to the grid it acts as backup and, when power is missing, the switch to the battery is invisible. For the startup surge of a small motor, a dedicated function raises the power ceiling for a moment, and runtime extends with one dedicated battery, just one.
It charges from the outlet, the sun or the car's cigarette lighter socket, and works without making itself heard. It's the reserve for anyone leaving for the weekend with a phone, a computer and a modem to keep running, who wants to carry a single object instead of three.

The rest of the data comes from 2 pages on the manufacturer's site, cited row by row in the table above.
A manual or a datasheet counts as a source even when the original file is hosted elsewhere: what matters is the document, not the server. Where that happens, it is stated above.

03 · Summary
Pros and cons
In favour
- The magnetic power bank detaches already charged and goes in a pocket, without disconnecting the rest. source
- When power is missing, the switch to the battery is invisible.
- Three AC outlets: more appliances together without carrying a power strip along.
- It starts a small motor that at startup needs more than it gives continuously.
Worth knowing
- Runtime extends with one dedicated battery, and only one: beyond that, it doesn't go further.
- The power bank charges from the power station: detached and empty, it has to be put back in place and waited for. source
- With the power bank attached it's over five kilos: in an everyday backpack, it's noticeable. source
