Capacity
DELTA Pro 3: +1,072 Wh (+35.4%).
This comparison targets buyers shopping for a high-capacity portable power station suited to home backup, off-grid living, or heavy-load job sites. The DELTA Pro 3 leads with 4096 Wh of LFP battery capacity and 4000W of running power, giving it a clear edge over the Explorer 3000 Pro's 3024 Wh NMC pack and 3000W output. That extra headroom showed up in device testing: the EcoFlow unit powered 48 of 53 appliances versus 47 for the Jackery.
Expandability further separates the two, since only the DELTA Pro 3 supports add-on batteries for scaling capacity over time. LFP chemistry also delivers 4000 rated cycles, double the Explorer 3000 Pro's 2000. The tradeoff is weight.
At 63.9 lbs, the Jackery is nearly 50 lbs lighter, a significant advantage for anyone who needs to move the unit frequently between vehicles, campsites, or job locations.
