At a Glance
This comparison targets buyers weighing a lightweight, solar-friendly unit against a higher-capacity station that can handle more demanding loads. The RIVER 2 Max delivers 500W of running power from a 512 Wh LFP battery and weighs just 13.4 lbs, making it easy to toss in a car for camping or day trips.
The Jump 1500X triples the output at 1500W with 3000W surge, pulls from a larger 828 Wh battery, and powered 33 of 53 tested devices versus 20 for the EcoFlow. It also supports UPS functionality and battery expansion, two features the RIVER 2 Max lacks.
The tradeoff is real: the VTOMAN tips the scales at 36.2 lbs, nearly three times the weight, and its solar charge time stretches to 8.3 hours compared to 3.3 hours for the EcoFlow on a 220W panel.
