Frequently asked questions

Is the DELTA 3 Max just a bigger DELTA 3 Plus?

Mostly yes on capacity and output. The EcoFlow DELTA 3 Max holds 2048Wh against 1024Wh and delivers 2400W against 1800W. Both list a 10 ms UPS. The listed solar input is where it flips. The DELTA 3 Plus states 1000W while the Max page lists 500W which may be per input.

How much heavier is the DELTA 3 Max?

The EcoFlow DELTA 3 Max is listed at 44.8 pounds. The EcoFlow DELTA 3 Plus is listed at 27.6 pounds. That is about 17 pounds more for the Max. For a unit that stays in one spot this hardly matters. For stairs or a car trunk it is worth weighing up.
