5.5mm/2.1mm DC Barrel Polarity Reversing Cable

A 5.5×2.1mm DC barrel polarity reversing cable that swaps centre-negative to centre-positive (or vice versa). Simply plug it inline between your DC power supply and device to reverse the polarity — no rewiring required.

This is useful for powering devices that use centre-negative barrel jacks (such as many guitar pedals and label printers) from standard centre-positive DC power supplies.
