At a Glance
This comparison targets buyers weighing a compact, lighter portable station against a high-capacity powerhouse built for heavier loads. The DELTA 2 Max delivers 2400W of running power and 2048 Wh of battery capacity, nearly doubling the C800 Plus on output and tripling it on stored energy. That gap shows in device coverage: the DELTA 2 Max powered 45 out of 53 tested devices, while the C800 Plus handled 24.
EcoFlow's unit also supports expansion batteries and accepts up to 1000W of solar input, making it far more capable for home backup and extended off-grid use. Surge capacity tells a similar story at 4800W versus 1600W. The tradeoff is weight and portability.
At 24 lbs, the C800 Plus is less than half the DELTA 2 Max's 50.7 lbs, a real advantage for hikers, car campers, or anyone who needs to move a station frequently.
