EcoFlow Infinity Cable

The Infinity cable connects the DELTA Pro to the Smart Home Panel. Keep in mind that only one Infinity Cable comes in kit with Smart Home Panel, so you don’t have to purchase it if you are planning to use Smart home panel with one DELTA Pro.
The only case where you might need to buy an Infinity Cable is when you plan to use Smart Home Panel with 2 Delta Pro units. Because the Infinity Cable doesn’t come in the box with the DELTA Pro, you cannot use Infinity cable to connect two DELTA Pros unless you do it via Smart Home Panel.
