The verdict
The EcoFlow RIVER Pro holds 208 Wh more — 41% more capacity, which on a fridge-freezer is the difference between 7 h 18 min and 9 h 32 min.
The EcoFlow RIVER 3 Max is 1 kg lighter, which matters if you carry it rather than wheel it.
Only one of the two has an indicative price recorded, so value is not comparable here.
They use different chemistries: the EcoFlow RIVER 3 Max is LFP and rated for 3,000 to 80% capacity, against 800 to 80% for the NMC unit. For anything that will be charged weekly, that alone decides it.
EcoFlow RIVER 3 Max refills faster from the mains — 1 h 10 min against 1 h 36 min.
Short answer. Buy the EcoFlow RIVER Pro if you want the hours and can live with 7.6 kg; buy the EcoFlow RIVER 3 Max if portability matters more than capacity. Neither is a bad buy — they are aimed at different jobs.
