Our verdict
Both are small, about 286 to 288 Wh, so they run a router for about 16 hours and a CPAP for about 8. If that's all you need, either will do. The difference is what happens when you plug in something bigger.
The RIVER 3 Plus is rated for 600 W continuous, double the Jackery's 300 W. In our calculator, that's enough to run a typical fridge for about 4 hours. The Explorer 300 v2 can't start one. The RIVER also takes more solar (220 W against 100 W), switches over faster (10 ms against 20 ms) and can be expanded to 858 Wh with an add-on battery. The Jackery can't be expanded.
The Jackery is lighter at 8.2 lb against 10.4 lb and has two USB-C ports against one. It's also covered by a 5-year warranty (3 years plus 2 when you register). EcoFlow doesn't list the RIVER 3 Plus warranty on its US product page, so check it before you buy.
For phones, laptops, a CPAP and camping, the Jackery is the lighter pick. If you want a small box that can also keep a fridge cold for a few hours during an outage, the RIVER 3 Plus is the one that can actually do it.
