The Delta 2, Delta Pro, and maybe other Ecoflow units use the third pin on a XT60i connector for signalling. Adding a resistor between the signal pin and minus pin makes the Delta 2 detect a generic XT60 as a solar charger instead of a car charger.
The car charger will still work as designed. Some power will be lost in the resistor. Or build your own car charger from a solar charge cable and car charge at 15 amps if you know what you are doing.
