Meh.......I'd rather a Bluetti Elite 100v2. More capacity and 1800w continuous while weighing in at like 25lbs. The pop up on Ebay with 5 year warranties for just over $300. When testing mine I was able to sustain 2600w for like 15 seconds......I was shocked.

Beware of using this as a UPS! I was impressed at first, using as a UPS but there are serious issues with the unit cutting AC power and turning off my computer, NAS, switch, and other devices for seemingly no reason even with the latest firmware (and I was no where near overloading the 600 watt capacity). Also there is no advertised surge protection, so I bought a good surge protector and then plugged the EcoFlow into it. Also these units won't go to battery power if the input AC voltage gets too low or too high (or it will but the limits are unsatisfactory (too low/high) for a computer UPS). And EcoFlow support told me (on 2026-03-12) "it is recommended to perform a full charge and discharge cycle once per month". I assume this is to maintain battery health and ensure the Battery Management System (BMS) remains accurately calibrated but there is no automated way to do this and no way to do it knowing that the AC outputs will stay on even if plugged into a wall outlet. This may be no big deal for some devices, but for other devices that need to stay on or risk corruption, it is a big deal for a UPS.
Using the 'backup reserve' feature to manually discharge the batteries will likely cut your AC power off even when the unit is still plugged into the grid, as it has done multiple times for me even with the unit indicating the battery is still at 20% or over (and with less than a 300 watt load). Updating the firmware also shuts off AC power. Unexpectedly shutting off the AC power when plugged into the grid is not acceptable for a UPS. My CyberPower UPS units didn't have these issues. I'm not happy that this has still not been fixed and EcoFlow support has been no help. In my opinion, these River 3 Plus units are definitely not "pro-grade" or "premium" UPS units. If they were then they wouldn't shut off AC power unexpectedly and you wouldn't have to manually baby the unit every 3 months by discharging and recharging manually. This becomes even more of an issue if you have multiple units because you have to manually manage each one.
The only reliable "solution" I have found to this is to use a normal lead acid UPS (like APC or CyberPower) plugged into the EcoFlow. I put my most critical devices on it (like computers and NAS) so they stay on when the EcoFlow fails to keep the AC power on. Other non-critical items that aren't such a big deal if they get powered off (i.e. smart devices, monitors, accessories) are not on the regular UPS and are directly connected to the EcoFlow AC output.
