The DJI Power 2000 and EcoFlow Delta 3 Plus sit a size class apart. DJI’s unit is around the 2kWh class, while the Delta 3 Plus is around 1kWh with the option to add batteries. DJI is a newer name in power stations but brings strong engineering and tight integration with its drones, while EcoFlow has one of the broadest lineups on the market.

At a glance

The main trade-off is built-in capacity versus a lighter base with expandability. Figures below are class-level ranges rather than lab measurements; exact capacity, output and weight vary by production batch and regional version, so confirm the current spec sheet before you order.

Factor DJI Power 2000 Delta 3 Plus
Capacity class ~2kWh ~1kWh, expandable
AC output class ~2,400-3,000W class ~1,800W class
Weight class ~45-50 lb ~25-30 lb
Special integration DJI drone fast-charging accessories Broad EcoFlow accessories and apps
Best fit Drone crews, longer outages Mixed use, lighter portable

Where the DJI Power 2000 wins

Capacity out of the box

Twice the energy in one box means a full night of fridge and internet or a full day of drone battery cycling without buying add-ons.

Drone workflows

For photographers and survey pilots in the DJI ecosystem, dedicated fast-charging accessories make field battery turnaround much quicker.

Higher output class

A larger inverter handles kettles, microwaves and tools more comfortably.

Where the Delta 3 Plus wins

Portability

At roughly half the weight, the Delta 3 Plus is much easier to carry to a campsite or move between rooms.

Lower entry price

If 1kWh is enough, you pay significantly less and can still expand later.

Mature ecosystem

EcoFlow has more accessories, home-integration options and a longer track record in power stations.

Runtime math on real loads

Runtime is simply usable watt-hours divided by load watts. We assume about 85% of rated capacity reaches your devices after inverter losses, which is typical for LiFePO4 stations running AC loads. The DJI unit’s roughly double capacity shows up clearly on continuous loads such as a fridge or CPAP.

Load Draw DJI Power 2000 (~2,048Wh class) Delta 3 Plus (~1,024Wh class)
CPAP (no humidifier) 40W ~43.5 h ~21.8 h
Refrigerator (avg) 150W ~11.6 h ~5.8 h
Laptop + router 90W ~19.3 h ~9.7 h
Space fan 50W ~34.8 h ~17.4 h
Coffee maker 900W ~1.9 h ~1.0 h

Weight versus capacity per trip

Every kilowatt-hour of LiFePO4 adds roughly 20-25 lb once the case and inverter are included. That is why the choice here is partly physical: a 2kWh-class unit around 45-50 lb is a two-hand lift into a truck bed, while a 1kWh-class unit can be carried to a picnic table with one hand. If you will move the station several times a day, the lighter unit plus an expansion pack left in the vehicle can be the more comfortable setup.

Drone battery math

A typical mid-size drone battery stores roughly 60-100Wh. Allowing for charging losses of about 15-20%, a 2kWh-class station can refill around 15-25 packs, while a 1kWh-class unit manages about 8-12. For a full day of aerial work, that difference matters.

Checklist before you order

  • Your peak load: add up everything that will run at the same moment and keep it under about 80% of the continuous inverter rating of the DJI Power 2000 or Delta 3 Plus.
  • Your daily energy: multiply each device’s watts by its hours of use, total it, then divide by 0.85 to find the rated capacity you need.
  • Surge: motors in fridges, pumps and compressors can briefly pull three to five times their running watts; check the surge rating, not only the continuous one.
  • Recharge path: confirm wall-charge time, maximum solar input and whether car or generator charging is supported.
  • Warranty and cycles: LiFePO4 units are typically rated for roughly 3,000+ cycles to 80% capacity; favour longer warranties and authorised sellers.

Which should you buy?

Buy the DJI Power 2000 if…

you fly DJI drones professionally or want 2kWh of storage in a single box for longer outages and bigger loads.

Buy the Delta 3 Plus if…

you want a lighter, cheaper station for camping, CPAP and short outages, with the option to add capacity later.

FAQ

Is DJI Power reliable?

DJI is newer to the category, but its units use LiFePO4 cells and come with warranty coverage comparable to established brands. As always, check current warranty terms and buy from an authorised seller.

Can the Delta 3 Plus match 2kWh with an extra battery?

Yes, adding an expansion pack brings it to about 2kWh or more, though the combined setup is heavier and may cost as much as or more than a single 2kWh unit.

Bottom line

The DJI Power 2000 is the better buy for drone crews and anyone wanting 2kWh in one box. The Delta 3 Plus is the smarter choice for lighter portable use and a lower entry price, with room to grow. Decide based on how much capacity you need on day one.
