At a Glance
This comparison targets anyone choosing between two popular LFP portable power stations in the mid-capacity range. The DELTA 2 pulls ahead with 1800W of running power and 2700W surge, compared to 1200W and 1600W on the C800 Plus.
That extra headroom shows up in device coverage: the DELTA 2 powered 39 out of 53 tested devices, while the C800 Plus handled 24 of 53. Battery capacity also favors the DELTA 2 at 1024 Wh versus 768 Wh, and its 500W solar input cuts recharge flexibility that the C800 Plus, capped at 300W, simply cannot match.
EcoFlow's unit is also expandable for added storage. The tradeoff is weight: at 24 lbs, the C800 Plus is roughly 2.5 lbs lighter, making it easier to grab for day trips or car camping where high wattage is less critical.
