I am willing to donate $10 to whom ever can tell me, definitively, which cigarette barrel power cord will fit my M712U ASUS VivoBook. Once recommended, I will purchase and verify. You will then be compensated via PayPal or some other TRUSTED and KNOWN transfer system. I am not willing to get Venmo, Cash App or the likes... Or, you purchase it, send it to me, I test it and reimburse you plus the $10... Thanks One at a time please, we will get to all of you eventually...
