Hi just recieved my new EB3A from Amazon. Out the box I have tried charging via solar panel, Bluetti, and via mains. This unit is not working, will not charge either way. This is not what i was hoping for. What the hell am I doing wrong???
@funkycookiecat Is it impossible to charge using both the adapter and the solar panel?
What is the open circuit voltage of the solar panel?
Have you tried car charging?
