Data from official source

EcoFlow RIVER 2 Pro is a lithium iron phosphate power station that sits between a backpack and a van: roomier than a day-trip unit, light enough for one person to move alone. It handles a camping fridge, a small tool, the equipment for a day of work away from the grid.

Plugged into the outlet it acts as backup, but the switch to the battery leaves a gap of about thirty milliseconds: lights and the modem don't notice, a computer might. To start a motor or a heating element that needs more than its continuous rating, there's a dedicated function that raises the ceiling for a moment.

It charges from the outlet, the sun, the car or USB-C, and from the grid it's back to nearly full in under an hour: the difference between waiting until the next morning and getting going right away. It's controlled from the buttons on the panel, and the app is for checking on it from a distance, not for making it work.

Which documents this page rests on

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

  • From the grid it's back to nearly full in under an hour: no waiting to get going again.
  • It starts a motor or a heating element that needs more than its continuous rating.
  • It also charges from the sun and the car's outlet: away from home it doesn't depend on a single outlet.
  • It handles a camping fridge while staying a weight one person can move alone.

Worth knowing

  • The switch to the battery leaves a gap of about thirty milliseconds: for equipment that can't tolerate it, it isn't the right choice.
  • Only one AC outlet: two plug-in appliances together need a power strip. source
