Summary: Possible & safe to connect an XT60 [on 1 end] -- 5.5x2.1 mm barrel [on other end] connection to a 300Wh portable solar "generator"?

Similar to Will's video of XT60 replacing mc4 on the 60w panel and Jackery 240 included mc4 cable, I want to do the same. But, the Jackery 240 included an mc4--8mm barrel cable, and my Golabs' is an mc4--5.5x2.1mm barrel. The jackery's 42W Max input with 12V~30V . I am not sure about the 2.1mm connector, but the Golab's 65v max input & MPPT controller supports voltage is 10.8-23.5V (3A).

Would I be able to cut wire with 2.1mm barrel attached from a standard 20v laptop power brick and attached an xt60 connector to the cut end? I have many power bricks. I can also cut the mc4 connector from the 2.1mm cable that came with the Golabs as well if need be. Amazon has lots of xt60--2.1mm FEMALE [not male] barrel cables. Though there are a few cables with the male barrel on ebay & one on Amazon. I don't know what the green block on that male barrel is...screw block?

I am wondering if there's any concern electrically? I did come accross someone mentioning barrel connection from power bricks are regulated or something like that.

Also, with the max 3a input, when a 100w panel [usually 5-6a] is connected, is the mppt limiting the amp to 3a?

THANKS!

I am going to end up doing the same thing using an xt60 female to 12v barrel male. Did you end up getting yours to work?
