Winner: Price
EcoFlow Delta 3 Max
Power Output
Identical on paper. Both deliver 2400W continuous with a 4800W surge and a 3400W X-Boost mode, enough for a refrigerator, a coffee maker, a washer or a circular saw according to EcoFlow. Neither separates itself here. The Delta 3 Max adds a sub-10 ms UPS switchover that EcoFlow lists on its spec sheet; the Delta 2 Max page does not claim one.
Winner: Power Output

Weight and Portability
The Delta 3 Max weighs about 20.3 kg (roughly 45 lb) and the Delta 2 Max 23 kg (50 lb). EcoFlow says the Delta 3 Max is 13% lighter than the previous generation 2kWh unit. Both are heavy for a one-person carry. A difference of 5 lb is noticeable on stairs and in a car boot, but not decisive. There is also a Delta 3 Max (Detachable Wheels) version at $1,299 for moving it around.
Winner: Weight and Portability

Solar and Charging Speed
The Delta 2 Max takes up to 1000W of solar across two inputs (500W on a single port) and EcoFlow quotes a full charge in as fast as 2.3 hours. It charges from the wall at 1800W. The Delta 3 Max is capped at 500W of solar and charges 0 to 80% in 68 minutes from the wall or a generator. For a large solar array or a van with panels on the roof, the Delta 2 Max recharges noticeably faster. For wall charging the difference is smaller.
Winner: Solar and Charging Speed
EcoFlow Delta 2 Max
Expansion and Longevity
The Delta 2 Max accepts up to two Delta 2 Max Smart Extra Batteries for 6144Wh, and EcoFlow publishes 3000 cycles to 80% capacity. The Delta 3 Max spec sheet lists no extra battery and no cycle count, only a claim of 10 years from automotive-grade LFP cells. If you might outgrow 2048Wh, or you want a published cycle number, the Delta 2 Max is the safer choice. The extra battery is expensive at $899, which is worth pricing before you assume expansion is cheap.

Final Verdict
The Delta 3 Max in the US, the Delta 2 Max if You Need to Scale or Buy in Europe
