EB55 with BougeRV panels

Hi I can’t seem to use my EB55 with a BougeRV 100 watt foldable panel. It says no charge. Maybe two panels in parallel would work? Any help is appreciated.

I saw your question under another thread and replied. Basically for anyone else reading, the Bouge RV cable from the solar panel was being connected to the EB55 AC power charging brick port instead of the yellow XT60 solar charging input port.
