Capacity
DELTA 2 Max: +1,779 Wh (+661.9%).
This comparison pairs a compact, ultra-portable unit against a high-capacity home backup powerhouse, so the two serve very different roles. The EB3A delivers 600W of running power from a 268.8 Wh LFP battery and weighs just 10.1 lbs, making it easy to toss in a car for day trips or small electronics charging.
The DELTA 2 Max operates at 2400W with 2,048 Wh of capacity, handles 45 of the 53 devices we tested, and accepts up to 1,000W of solar input for serious off-grid or emergency scenarios. It also supports battery expansion for even longer runtime.
The tradeoff is weight and bulk: at 50.7 lbs, the DELTA 2 Max is five times heavier than the EB3A, which limits its grab-and-go appeal.
