Capacity
RIVER 2 Pro: +499 Wh (+185.7%).
This comparison targets buyers choosing between two compact LFP stations for light-duty backup and portable power. The RIVER 2 Pro delivers 800W of running power and 768 Wh of capacity, nearly tripling the EB3A's 268.8 Wh reserve while adding 200W more continuous output.
Surge capability follows the same pattern: 1,600W for the RIVER 2 Pro versus 1,200W for the EB3A. In device-compatibility testing across 53 appliances, the RIVER 2 Pro powered 22 devices to the EB3A's 21, earning a slightly higher overall score of 44 to 41.
The RIVER 2 Pro also edges ahead in cycle life at 3,000 versus 2,500. The tradeoff is weight and solar recharge time: the EB3A weighs just 10.1 lbs and refills via solar in roughly 2.4 hours, while the RIVER 2 Pro tips the scale at 18.3 lbs and needs about 5 hours of sun to reach full charge.
