EcoFlow RIVER 2 Max 500 Portable Power Station (499Wh)

By Tom Calder

Our verdict · Researched
3.8 / 5

499Wh and 500W at 13.2 lb, full from the wall in 60 minutes by EcoFlow's figure: a router, CPAP and lights overnight, not a fridge.

How this review works

This is a Researched review: we haven't used this product. We check every specification against at least two independent sources, re-check the US price on a schedule where we can track it automatically, and say plainly who it isn't for. Commissions never change a rating.
