At a Glance
This comparison targets buyers choosing between two 768 Wh LFP portable power stations with identical battery capacity and 3,000-cycle longevity. The AC70 pulls ahead on raw output, delivering 1,000W of running power and a 2,000W surge versus the RIVER 2 Pro's 800W and 1,600W surge.
Solar charging is another clear divider: the AC70 accepts up to 500W of solar input and can recharge in roughly 2.7 hours, while the RIVER 2 Pro tops out at 220W and needs about 5 hours. Device compatibility testing across 53 products gave the AC70 a 24-device pass rate compared to 22 for the RIVER 2 Pro.
The tradeoff is weight. At 18.3 lbs, the RIVER 2 Pro is more than 4 lbs lighter than the 22.5 lb AC70, a real advantage for anyone hauling gear on foot or loading a packed vehicle.
