DJI’s Power 2000 and EcoFlow’s DELTA 3 Max store exactly the same amount of energy, 2,048Wh of LiFePO4, but they’re built for different buyers. DJI’s spec page lists 3,000W of continuous AC output, four 140W/65W USB-C ports and expansion to 22,528Wh. EcoFlow’s spec sheet lists 2,400W, 1,800W wall charging and a lighter 44.8 lb body, with no expansion port. On Oct. 17, 2026, DJI’s store listed the Power 2000 at $1,299. When we last checked the DELTA 3 Max on Amazon, on Oct. 14, it was $879 against a $1,199 list price.

Which should you buy?
- DJI Power 2000 if you need 3,000W for tools or a big appliance, lots of USB-C for camera and drone gear, a path to more than 20kWh, or very fast alternator and solar charging through DJI’s accessories.
- EcoFlow DELTA 3 Max if you want the same 2kWh for a lot less money, in a lighter box, with a standard solar input you can plug panels into without an adapter.

Round by round
| Category | Edge | Why |
|---|---|---|
| Raw AC power | Power 2000 | 3,000W vs 2,400W continuous |
| Heating appliances | Close | DJI’s 3,000W runs most heaters outright; EcoFlow’s X-Boost runs resistive loads up to 3,400W at reduced power |
| USB charging | Power 2000 | Eight USB ports, including two 140W PD 3.1 |
| Wall charging | Close | 55 vs 68 minutes to 80% |
| Solar, out of the box | EcoFlow | Built-in 500W XT60i; DJI needs an adapter for anything over about 100W |
| Solar, maximum | Power 2000 | Up to 1,800W with DJI’s Super Fast Charger |
| Charging while driving | Power 2000 | Up to 1,000W alternator charging vs EcoFlow’s 500W unit |
| Expansion | Power 2000 | Up to 22.5kWh vs none |
| Quiet operation | EcoFlow | ≤25 dB at 600W |
| Portability | EcoFlow | About 3.7 lb lighter |
| Warranty | Tie | Five years each (EcoFlow’s requires app registration) |
| Value per watt-hour | EcoFlow | About $0.43/Wh vs $0.63/Wh at the prices above (my math) |
Runtime: practically identical (estimates)
With the same 2,048Wh of capacity, runtime at a given load depends mostly on inverter efficiency and idle draw, not on the brand. I use about 82% delivered for both units, which is my assumption, not a measurement.
| Load | Watts | Either unit (estimate) |
|---|---|---|
| Router + modem | 20W | ~3 days |
| Full-size fridge | ~63W average | ~26 h |
| CPAP, no humidifier | 40W | ~40 h |
| Laptop + monitor | 100W | ~17 h |
| Window AC | 500W | ~3.3 h |
| Microwave | 1,200W | ~80 min of cooking |
| Space heater, high | 1,500W | ~65–70 min |
The difference shows up at the top end. A 2,600W saw or a 2,800W combination of loads runs on the DJI but trips the EcoFlow. Below 2,400W, either one does the job. For a worked heater example, see whether the EcoFlow DELTA 3 Max can run a space heater.
Solar: the biggest design difference
The EcoFlow is the simpler solar station. Plug an MC4-to-XT60i cable into its 500W input, keep the string between 11 and 60V, and it charges. Our series vs parallel wiring guide shows how to build that string.
The DJI has no MC4 solar port. Its two SDC ports accept DJI’s 400W MPPT adapter module, which takes up to three panels in parallel only, or the 1.8kW Solar/Car Super Fast Charger for big arrays. That’s more capacity than the EcoFlow can ever take, but it comes through extra accessories. Our DJI Power 2000 solar guide walks through both routes.
Running a 12V fridge: DC socket vs SDC
For campers, the DC side matters as much as the inverter. The DELTA 3 Max has an ordinary 12V car socket on the back (12.6V, 10A, 126W), so a compressor fridge plugs straight in and skips the inverter’s idle draw. In our DELTA 3 Max 12V fridge guide, a fridge averaging about 15W on DC comes out at roughly five days, against under two days through AC (estimates).
The DJI Power 2000 has no conventional 12V socket. DC goes out through two proprietary ports that need the maker’s own cables, and those same two ports are shared with chargers and add-on batteries. If you plan to run a 12V fridge, a solar adapter and an expansion battery at the same time, map out which accessory gets which port before the trip.
Five situations, one pick each
| Situation | Pick | Deciding factor |
|---|---|---|
| Weekend car camping with a 12V fridge | DELTA 3 Max | Built-in 12V socket, lighter, quieter |
| Video shoot with drones, cameras and laptops | Power 2000 | Eight USB ports, two at 140W |
| Contractor running a miter saw or compressor | Power 2000 | 3,000W continuous |
| Apartment backup for fridge, router and lights | DELTA 3 Max | Same capacity for less money; ≤25 dB |
| RV that wants multi-day off-grid capacity | Power 2000 | Expansion to 22.5kWh, 1kW alternator charging |
Noise and placement
EcoFlow rates the DELTA 3 Max at 25 dB or less at a 600W load, measured at 1 m. DJI rates the Power 2000 at 30 dB or less in its Standard Recharge mode at 1 m. Both figures are quiet enough for a bedroom at light loads. Expect either fan to get louder during fast wall charging or near full output. The EcoFlow is longer (19.4 in) but narrower, and the DJI is shorter (17.6 in) but taller, so measure the shelf, trunk or cabinet where it will live.
On the road
For RVs and overland rigs, alternator charging often matters more than solar. DJI’s 1kW Super Fast Car Charger can add roughly 1kWh per hour of driving (estimate, before losses). EcoFlow’s 500W alternator charger adds about half that. Our overlanding power station picks include both units.
Home backup
Both make good UPS-style backups for a fridge, router and lights, with switchover at or under 10 ms. The bigger unit pulls ahead in a long outage, because you can keep adding battery packs. The EcoFlow is a fixed 2,048Wh. For multi-day outages you’d pair it with solar or a generator, or step up to EcoFlow’s expandable DELTA 3 Ultra line. Either way, set the AC outlets to stay on in the app so a fridge isn’t cut off by an auto-off timer during a quiet night.
FAQ
Is the DJI Power 2000 better than the EcoFlow DELTA 3 Max?
It’s more capable, with 3,000W of output, more USB-C, expansion to 22.5kWh and faster solar and alternator charging through accessories. The DELTA 3 Max is lighter, quieter and much cheaper for the same 2,048Wh.
Which charges faster from the wall?
DJI quotes 0–80% in about 55 minutes and EcoFlow quotes 68 minutes, so both are fast.
Can I add batteries to the DELTA 3 Max?
No. It has no expansion port. The DJI Power 2000 takes up to 10 Expansion Battery 2000 packs.
Which is better for solar?
For plug-and-play solar up to 500W, the EcoFlow. For big arrays, the larger system with its optional high-power charger.
Do they have the same runtime?
Very close. Both hold 2,048Wh, so at the same load the difference comes down to inverter efficiency.
Bottom line
At the same 2,048Wh, this comes down to headroom versus value. The DJI Power 2000 is the more expandable, higher-output system for creators, RVers and long home outages. The EcoFlow DELTA 3 Max does the everyday 2kWh jobs, like a fridge, CPAP, laptop or a weekend at camp, for hundreds less in a lighter, quieter box.
