The verdict

The Bluetti AC70 holds 48 Wh more — 7% more capacity, which on a fridge-freezer is the difference between 9 h 32 min and 10 h 44 min.

The EcoFlow RIVER Pro is 2.6 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 Bluetti AC70 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.

Bluetti AC70 refills faster from the mains — 1 h 15 min against 1 h 36 min.

Short answer. Buy the Bluetti AC70 if you want the hours and can live with 10.2 kg; buy the EcoFlow RIVER Pro if portability matters more than capacity. Neither is a bad buy — they are aimed at different jobs.
