DJI Power 1000 vs EcoFlow DELTA 3 Plus
DJI Power 1000 (1,024 Wh, 2,200 W) vs EcoFlow DELTA 3 Plus (1,024 Wh, 1,800 W). Their batteries are about the same size, so the differences are in output, charging and features. Here is where each one comes out ahead, based on the manufacturers' published specs.
Each row has its own scale, and the longer bar fills the row. Figures are the manufacturers' published specs.
Choose the Power 1000 for…
- high-power appliances: 2,200 W vs 1,800 W continuous output
- starting pumps and compressors: 4,400 W vs 3,600 W surge
Choose the DELTA 3 Plus for…
- room to grow: expands to 5,120 Wh with extra batteries
- faster solar charging: up to 1,000 W vs 800 W of panels
- UPS use: 10 ms switchover vs 20 ms
- fast wall charging: 1,500 W vs 1,200 W AC input

Our verdict
Both hold 1,024 Wh, so neither lasts longer: about 15 hours on a typical fridge and 29 on a CPAP in our calculator. They're built for different people, though.
The DJI Power 1000 has more muscle. It's rated for 2,200 W continuous and 4,400 W surge, against 1,800 W and 3,600 W, which gives it more headroom for a microwave, a hair dryer or a stubborn motor. The catch is that it has only two AC outlets. The DELTA 3 Plus has six.
The EcoFlow is the better home-backup tool. It switches over in 10 ms against 20 ms, charges from the wall faster (1,500 W against 1,200 W), takes 1,000 W of solar against 800 W and can be expanded to 5,120 Wh. The DJI can't be expanded, and its solar input runs through DJI's own MPPT adapters rather than a standard solar port. The EcoFlow is also about a pound lighter.
If you mostly need to run a couple of power-hungry things at once, the DJI's output rating is the draw. For powering several devices through an outage, the DELTA 3 Plus is the more practical box. Note that DJI's 5-year warranty is 3 years plus 2 more when you register, and its cycle rating is counted to 70% capacity.
