I am having a hard time finding the above cord. I thought I had one as backup that was supposed to be the correct one but the 8mm connector does not look right. It has a piece on it that stops it from inserting all the way. If anyone has a link to Amazon preferably I would really appreciate it...

I am new here and have learned so much already but I just received a new BluettiEB150 today. Everything seems fine except the front fan is very loud. I suspect it is misaligned, impinging or has an off kilter fan blade etc. I hate to send it back across the country and wait to have it repaired...
