At a Glance
This comparison targets buyers choosing between EcoFlow's two entry-level LFP portable power stations. The RIVER 2 Pro triples the usable capacity (768 Wh vs. 256 Wh) and nearly triples running output (800W vs. 300W), which translates directly into broader device coverage: it powered 22 of our 53 tested devices compared to 17 for the standard RIVER 2.
Surge capacity jumps from 600W to 1,600W on the Pro, letting it start small compressors and power tools the base model simply cannot handle. Solar input doubles as well (220W vs. 110W), though full solar charge time stretches to about 5 hours versus 3.3 hours for the smaller unit.
The tradeoff is weight: at 18.3 lbs the Pro is more than twice as heavy as the 7.7 lb RIVER 2, and it lacks the 30 ms UPS switchover the base model offers for light home-backup duty.

The Bottom Line
Pick the RIVER 2 if you need an ultralight grab-and-go battery for phones, laptops, and small electronics, especially if its 30 ms UPS transfer time matters for keeping a modem or desk setup alive during brief outages. Choose the RIVER 2 Pro when you need to run higher-draw appliances on the road or at a campsite and want the flexibility of faster solar replenishment through a 220W panel. The Pro earns the win here with a score of 44 to 33, delivering meaningfully wider device support without sacrificing LFP longevity.
