Will an EcoFlow RIVER 3 Plus run a 12V portable fridge/freezer? (US 120 V)
Yes, it runs it — no usable-capacity figure see why below ↓
Every check passes. What this page will not do is turn a nameplate watt-hour rating into hours — see the evidence below for why.

Two numbers decide this, and readers use them interchangeably: watts are the ceiling on what the inverter holds at any instant, watt-hours are how much energy the battery holds. A machine can have plenty of one and not enough of the other.
The verdict is a calculation, not a lookup. What it will not do is print a runtime, and the reason is specific: we read 4 of EcoFlow’s own published documents on 2026-08-08 and found no depth of discharge or inverter efficiency for the US 120 V build in them, so there is no usable-capacity figure to divide.
Where those numbers come from
A blank is never left blank. A field we have found no figure for says so, and a field whose sources disagree — two documents, or one document with itself — says that instead of picking one.
No usable-capacity figure for this machine
EcoFlow states a nameplate watt-hour number for it, and we read 4 of EcoFlow’s own published documents on 2026-08-08 and found no depth of discharge or inverter efficiency for the US 120 V build in them. Dividing the nameplate by this load would be wrong by 20–35% in the flattering direction, so this page shows the nameplate for what it is and refuses to turn it into hours.

Energy rate instead of a runtime
90 Wh per hour while it is actually runningThis number needs no battery figure at all, which is why this page can give it when it cannot give hours. Divide any usable-capacity figure you trust by it and you have your own runtime, with our arithmetic visible instead of hidden.
What a 12V portable fridge/freezer demands
The engine checked 180 W — where a record publishes both an absolute inrush and a multiple of running power, the more demanding of the two is used rather than the flattering one.
Start-up figure Manufacturer-stated
The start-up figure is published by the manufacturer for this device, so it describes the actual hardware rather than a category.

If this is not the pairing
BLUETTI Elite 30 V2 (US 120 V) reaches the same conclusion on a 12V portable fridge/freezer at 600 W continuous, and it is $239. Cheaper is only cheaper when the answer is the same — this one is. See that pairing →
