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 2 Max is 1.6 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 2 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 2 Max refills faster from the mains — 1 h 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 2 Max if portability matters more than capacity. Neither is a bad buy — they are aimed at different jobs.
