Just curious what type of a male connector I need in order to plug a string of 12v lights I am making into this 12v port? I found " DC Power Pigtail Cable,16AWG DC Barrel Plug Connector 2.1mm x 5.5mm DC Male Plug to Bare Wire Open End Power Wire Supply Repair Cord for CCTV Security Camera,12V 24V 36V Adapter 3FT" on amazon that may work but I’m not positive, onlt going to be about 6 LED pucks I am going to string together along with an on/off switch. Also, is it neccessary to put a fuse on the string or will my bluetti handle that without? thank you for your time.
