The verdict

The EcoFlow RIVER Pro holds 40 Wh more — 6% more capacity, which on a fridge-freezer is the difference between 9 h 32 min and 9 h 41 min.

It is also the lighter of the two at 7.6 kg, which settles the argument.

Only one of the two has an indicative price recorded, so value is not comparable here.

They use different chemistries: the UGREEN PowerRoam 600 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.

UGREEN PowerRoam 600 refills faster from the mains — 1 h 30 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 UGREEN PowerRoam 600 if portability matters more than capacity. Neither is a bad buy — they are aimed at different jobs.
