These two stations store exactly the same 2,048 Wh, so the choice comes down to what you need around that battery. Choose the DJI Power 2000 if you want 3,000 W of output or plan to add batteries later, up to 22,528 Wh. Choose the EcoFlow DELTA 3 Max if you want a lighter box with a built-in solar input and a listed noise rating for indoor use.
Everything here comes from the spec sheets EcoFlow and DJI publish for the US, checked in November 2026. We have not used either unit ourselves, so treat this as a side-by-side reading of the makers’ numbers, not a field test.
EcoFlow DELTA 3 Max: who is it for?
EcoFlow DELTA 3 Max
- Capacity
- 2,048 Wh
- AC output
- 2,400 W
- Solar input
- 500 W
- Weight
- 44.7 lb
Who it's for: Home backup buyers who want 2 kWh with 20 A outlets in a quiet box.
Strengths
- 2,048 Wh with 2,400 W output
- 25 dB at 600 W (maker's test)
- Under 10 ms UPS switchover
Weaknesses
- Solar input only 500 W for a 2 kWh battery
- 0-80% takes 68 minutes on AC
- Heavy at 44.7 lb
The DELTA 3 Max suits someone who wants 2 kWh in one box and has no plan to grow it. It runs four 120 V outlets at up to 20 A each, 2,400 W in total, and X-Boost lets suitable appliances run at up to 3,400 W. EcoFlow lists its switchover at under 10 ms and its noise at 25 dB or less at 600 W, measured at 1 m. That makes it easy to keep beside a desk or in a bedroom.
Charging from the wall is a strong point. Its 1,800 W AC input reaches 80% in 68 minutes, and it can also charge from a generator or an alternator charger. The 5-year warranty needs EcoFlow app registration to reach that length; the standard term is 3 years.
The weak side is solar and growth. It accepts 500 W of solar, and EcoFlow lists 3.43 hours to get from 0 to 80% at that rate. An expansion battery is not listed, so 2,048 Wh is what you get.
DJI Power 2000: who is it for?
DJI Power 2000
- Capacity
- 2,048 Wh
- AC output
- 3,000 W
- Expansion
- Up to 22,528 Wh
- Weight
- About 48.5 lb
Who it's for: People who want high output from a 2 kWh station and may add batteries later.
Strengths
- 3,000 W output
- Takes up to 10 expansion batteries
- Rated to keep over 80% capacity after 4,000 cycles
Weaknesses
- Solar charging needs a separate DJI module or charger
- Heavy to carry at about 48.5 lb
The DJI Power 2000 is for a buyer who wants more muscle now and more storage later. It is rated for 3,000 W of AC output, 600 W more than the DELTA 3 Max. It can take up to 10 expansion batteries for 22,528 Wh in total, which is the biggest reason to pick it.
Its LFP cells are rated to keep over 80% of capacity after 4,000 cycles. DJI lists a switchover of 0.01 seconds, the same 10 ms window as the EcoFlow, and a 5-year warranty with no registration step mentioned.
Solar is where it asks for extra gear. You need DJI’s adapter module for 400 W, or the 1.8 kW charger for up to 1,800 W. It is also the heavier of the two at about 48.5 lb, and DJI does not list a noise rating.
How do the specs compare?
| DELTA 3 Max | DJI Power 2000 | |
|---|---|---|
| Capacity | 2,048 Wh | 2,048 Wh |
| Battery | LFP | LFP, over 80% after 4,000 cycles |
| AC output | 2,400 W, X-Boost 3,400 W | 3,000 W |
| Expansion | Not listed | Up to 10 batteries, 22,528 Wh |
| Solar input | 500 W built in | 400 W with the adapter module, up to 1,800 W with the 1.8 kW charger |
| Switchover | Under 10 ms | 0.01 seconds |
| Noise | 25 dB or less at 600 W | Not listed |
| Weight | 44.7 lb | About 48.5 lb |
| Warranty | 5 years with app registration | 5 years |
Does the extra weight buy you anything?
Since both hold 2,048 Wh, runtime on a single charge is a tie. If 85% of the battery reaches your devices, each delivers about 1,740.8 Wh, or roughly 5.8 hours on a steady 300 W load.
Per pound, the DELTA 3 Max stores about 45.8 Wh and the DJI Power 2000 about 42.2 Wh. The DJI’s 3.8 extra pounds buy you 600 W more output and a path to add batteries, not more energy in the base unit.
How to choose
- You run several big loads at once: the DJI Power 2000’s 3,000 W rating gives more headroom.
- You may need several days of backup later: only the DJI lists expansion batteries.
- You charge mainly from panels and want no extra parts: the DELTA 3 Max takes 500 W of solar directly.
- The station will sit in a living space: the DELTA 3 Max is the one with a published noise figure.
- You carry it often: the DELTA 3 Max is 3.8 lb lighter.
Check the label on each appliance you plan to run and add up the watts before you decide between 2,400 W and 3,000 W.
FAQ
Do the EcoFlow DELTA 3 Max and DJI Power 2000 have the same capacity?
Yes. Both list 2,048 Wh of LFP battery capacity, so a single charge runs the same load for about the same time. The differences are output, expansion, solar input, and weight.
Can I add batteries to the EcoFlow DELTA 3 Max?
EcoFlow does not list an expansion battery for the DELTA 3 Max. The DJI Power 2000 can take up to 10 expansion batteries for 22,528 Wh in total.
Can the DJI Power 2000 charge from solar panels on its own?
No. The DJI Power 2000 needs DJI’s adapter module for 400 W of solar or the 1.8 kW charger for up to 1,800 W. The EcoFlow DELTA 3 Max has a 500 W solar input built in.
Which one is better as a backup for a computer?
Both list a 10 ms switchover: under 10 ms for the EcoFlow DELTA 3 Max and 0.01 seconds for the DJI Power 2000. The DELTA 3 Max also lists 25 dB or less at 600 W, which matters if it sits near your desk.
