The Bottom Line
Grab the EB3A if you prioritize portability and need the extra wattage headroom for appliances that push past 500W. Choose the RIVER 2 Max if longer runtime per charge matters more, since its 512 Wh battery nearly doubles the EB3A's capacity and its 3,000-cycle lifespan adds staying power over the years. Overall, the EB3A takes a narrow win on device coverage and power output, making it the stronger pick for most portable use cases.
