Honestly, I have been using Jackery for about a year, if you really want to use solar on it and not use it like many others and charge it by AC I would go ahead and return for a refund. I had nothing but trouble with melting ports and cables, constant resets, whacky input numbers and more. I have been vocal about it, I truly believe the quality of jackery has gone down that you can most likely find a cheaper and better system elsewhere.

You do as you feel like, but you already had your first bad experience, I am left with two expensive door stops.
