At a Glance
This comparison targets buyers shopping for an ultra-portable LFP power station under 300 Wh. The EB3A delivers twice the running watts (600W vs 300W) and double the surge capacity at 1,200W, which directly translates to broader device coverage: it powered 21 of 53 tested devices compared to the RIVER 2's 17.
Solar recharging is faster too, topping out at 200W input for a full charge in roughly 2.4 hours versus 3.3 hours on the RIVER 2's 110W max. Battery longevity is close, though the RIVER 2 edges ahead with 3,000 rated cycles to the EB3A's 2,500.
The RIVER 2 also adds a 30 ms UPS function the EB3A lacks and shaves 2.4 lbs off the carry weight at just 7.7 lbs. Picking between them comes down to whether you prioritize raw power headroom or lighter grab-and-go convenience with basic backup switching.
