DC Barrel Jack Y-Adapter Power Supply Splitter DC5525 M to DC5525 F & DC5525 F
Split your DC Power supply to power two different devices. The male is DC5525 (5.5 x 2.5mm). The females are DC5525 (5.5 x 2.5mm) and DC5521 (5.5 x 2.1mm). At the very least, you can use it as a converter from thick pin to thin pin. That was my original intention before going with a different solution.
