Frequently Asked Questions
Q: What is the maximum current this cable supports?
A: The 18 AWG copper conductors support up to approximately 5–7A at 12V for a 6-foot run. Always verify against your power supply's rated output.
Q: Is this cable center positive or center negative?
A: The 2.1mm x 5.5mm barrel connector passes through whatever polarity your power supply outputs. Polarity is not fixed by the cable itself.
Q: Will this work with my 12V or 24V LED strip?
A: Yes. Compatible with any DC power supply using a 2.1mm x 5.5mm barrel connector, regardless of voltage (within the cable's rated current limits).
