EcoFlow DELTA 2 Max (2048) vs EcoFlow DELTA 3 Max Plus

What separates these two

• AC output, non-stopThe DELTA 2 Max (2048) states 2,400 W (continuousContinuous output The power the station can supply non-stop. This is the figure that decides which appliances it can run, like a 1,000 W microwave.); the DELTA 3 Max Plus states 3,000 W (continuous), 25% more.This means the DELTA 3 Max Plus can run bigger appliances, ones that need more power, from its 240 V outlets.

• Stated warrantyThe DELTA 2 Max (2048) states 2 years (plus 3 more years on conditions the brand sets); the DELTA 3 Max Plus states 5 years, 3 years longer.This means the DELTA 3 Max Plus's brand covers it for longer.

Price and price per Wh aren't compared here yet. That needs a second shop selling each one for about the same price (within 10%), which shows the price is real. Today: price, DELTA 2 Max (2048) $2,341 and DELTA 3 Max Plus $2,999; price per Wh, DELTA 2 Max (2048) 114.3¢ and DELTA 3 Max Plus 146.4¢.

Can't be compared as the brands list themCan't be compared The two brands give this figure in different ways, or only one brand gives it. For example, one counts battery charges until 80% of the capacity is left and the other until 70%. Set side by side, the numbers would mislead, so both are shown and neither is put ahead.

• 12 V car socketThe DELTA 3 Max Plus states 10 A (at 12.6 V). The brand doesn't give this figure for the DELTA 2 Max (2048).This means the two can't be compared on this until both brands publish it.

A difference is listed above only when both brands measure a figure the same way and the gap is at least: capacity: 10% or more; price: 10% or more; price per Wh: 10% or more; AC output, non-stop: 15% or more; weight: 8% or more; 12 V car socket: any difference; solar input: 20% or more; wall charging, empty to full: 20% or more; cycle life: 20% or more; stated warranty: any difference; UPS switchover: 5 ms or more; expansion batteries: one has it and the other doesn't; AC surge: 15% or more. Every comparison on this site uses the same gaps.

Fridge runtime for both

How long each would run an example fridge, a Dometic CFX5 45, with no solar and no driving. Its manufacturer says it uses 0.76 Ah an hour at 12 V when it is 32 °C outside and 4 °C inside. The brands don't publish some of the figures this needs. Where someone has tested the station, their result is used; otherwise both use the same ranges, taken from tests of other stations. For the DELTA 2 Max (2048), tests of this exact station give its own draw (measured by The Technology Man) and 240 V shareShare delivered How much of the capacity on the box actually comes out of a socket, as a percentage. Testers run a steady load until the station switches off and count what came out. The rest is kept back to protect the battery or lost as heat making 12 V or 240 V. (measured by The Technology Man). For the DELTA 3 Max Plus, tests of this exact station give its own draw (measured by The Technology Man) and 12 V share (measured by The Technology Man).

The middle estimates are 2.4 days apart.This means the DELTA 3 Max Plus is likely to run the fridge for longer.

The biggest unknown is the station's own drawStation's own draw Power the station uses itself while an outlet is switched on: its screen, its electronics and the circuit that makes 12 V or 240 V.

Charging paths

“Not stated” means the brand's website and manual don't give that figure (checked 29 Sept 2026).

All the specs side by side

Capacity is the nameplate figure in watt-hours (Wh), the one on the box. AC output is the power a station can supply non-stop, not a short burst. Weight is the station on its own. A figure measured another way is shown with a note saying how, and isn't compared with the others.

What neither brand tells you

These figures would help answer the questions above, but neither brand gives them (checked 29 Sept 2026):
