At a Glance
This comparison targets buyers choosing between a high-capacity home backup system and a portable solar generator. The Delta Pro Ultra delivers 6,000W of running power with 6,144 Wh of capacity, nearly tripling the Explorer 2000 v2's 2,200W output and 2,042 Wh battery. That gap shows up in device coverage: the Delta Pro Ultra powered 52 of 53 tested devices, while the Explorer 2000 v2 handled 45.
Solar charging reinforces the divide, with the EcoFlow unit accepting up to 5,600W of panel input versus just 400W for the Jackery. Expandability on the Delta Pro Ultra also means you can scale storage over time. The tradeoff is weight and mobility.
At 39.5 lbs, the Explorer 2000 v2 is easy to move around a campsite or apartment, while the 182.1 lb Delta Pro Ultra is essentially stationary once placed. The Jackery also offers 20ms UPS functionality, a feature the EcoFlow lacks.
