The short answer on DJI Power 2000 vs EcoFlow Delta 3: the EcoFlow listing describes a complete power station you can plug loads into, while the DJI listing describes an expansion battery and hand truck combo that pairs with a DJI Power 1000. We compared the two listings on capacity, output, charging, size and warranty terms. Pick the EcoFlow side for a standalone station, and pick the DJI side only if you already own the matching DJI station and want more capacity that moves as one unit.

We copied each rating from the seller’s listing as the brand states it; data date 5 November 2026.
Capacity and what each listing is
The two listings are different kinds of gear, and that shapes the whole comparison. The DJI listing is a Power Expansion Battery 2000 with a hand truck: a 2048Wh add-on battery that the listing says is comparable in size to the 1024Wh DJI Power 1000, and the compatibility line names the DJI Power 1000. The EcoFlow listing is a complete station: the DELTA 3 Classic, a 1024Wh LiFePO4 power station with its own AC and USB-C outputs. So the DJI side states more watt-hours, but only as capacity you add to a station you already own, while the EcoFlow side states a full station as a single unit.
Output and charging
Only the EcoFlow listing states output and charging figures. It lists 1800W of continuous AC output with 3600W surge, X-Boost support for loads up to 2600W, and 100W USB-C output. Charging is 0-80% in 45 minutes on AC, and a full solar recharge in 2.5 hours with a 500W solar panel, sold separately. The DJI listing states no AC output, no USB output and no charge time: it is a battery and a hand truck, so its output depends on the station it pairs with. A switch under 10 milliseconds is listed for the EcoFlow, for PCs, servers and medical equipment.
Size, weight and moving them
The DJI listing gives the most moving detail. The expansion battery weighs approx. 16.5 kg and measures 448.5 by 225 by 234 mm, while the hand truck weighs 4.6 kg and measures 49 by 33 by 98 cm. The hand truck has a retaining bar that secures to the rear screw holes of the expansion battery and a ratchet strap that secures the power station and expansion battery vertically, and the listing recommends holding a maximum of one power station and two expansion batteries. The EcoFlow listing gives dimensions of 7.9 by 11.1 by 15.7 inches and states no weight, so the two sides cannot be weighed against each other.
What the listings leave unclear
The DJI listing disagrees with itself on size. The bullets give the battery as 448.5 by 225 by 234 mm, while the spec table gives 17.91 by 25.79 by 13.07 inches, and those two sets do not line up, so use the bullet figures. The spec table also says NumberOfItems 1, while the box list names a hand truck base, a handle, a retaining bar, an expansion battery and a cable. The EcoFlow listing leaves weight, handle and wheels unstated, and it states the DELTA 3 Classic is not compatible with Delta 3 Series Smart Extra Battery and DELTA 2 Smart Extra Battery, so no extra battery path is listed for it.

Where the points went
The Solar Score weighs performance, build, value, safety and warranty. For power stations, safety means a battery management system, stated protections or a UPS switch the listing names; the EcoFlow states a smart Battery Management System and a switch under 10 milliseconds, while the DJI states a retaining bar and ratchet strap that secure the load. Both listings state a warranty term, from 1 year to 5 years. How we pick explains the weights.
| Product | Solar Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| EcoFlow Delta 3 Classic | 9.7 | 32 | 22 | 21 | 8 | 3 |
| DJI Power Expansion 2000 | 9.4 | 26 | 20 | 19 | 4 | 1 |
We place weighted points on a scale whose ends are 9.2 and 9.8. Because the mapping is straight, a unit with more points never shows less.
DJI Power 2000 vs EcoFlow Delta 3: which should you choose?
Choose the EcoFlow Delta 3 Classic if you want a complete station: it states its own 1024Wh capacity, 1800W continuous output, fast AC charging and a 5-year manufacturer warranty. Choose the DJI Power Expansion Battery 2000 combo if you already own a DJI Power 1000 and want 2048Wh of extra capacity that rolls as one unit on the included hand truck. If you own no DJI station, the DJI listing on its own gives you a battery with no stated output, so the EcoFlow side is the pick for a first station.
| If you need | Look at |
|---|---|
| A complete station | EcoFlow Delta 3 Classic, 1024Wh |
| Most watt-hours stated | DJI Power Expansion Battery 2000, 2048Wh |
| Longest stated warranty | EcoFlow Delta 3 Classic, 5 years |
| Stated fast charging | EcoFlow Delta 3 Classic, 0-80% in 45 minutes |
Sizing Notes
- Match the DJI expansion battery to a DJI Power 1000, the compatibility the listing states.
- Match the EcoFlow 1024Wh capacity and 1800W continuous output to the loads you plan to run.
- Plan solar recharge around the 500W panel figure the EcoFlow listing states; the panel is sold separately.
- Keep the hand truck load to one power station and two expansion batteries at most, per the DJI listing.
- Check cable and fuse figures in the manual before connecting a panel.
