Power bar too full of multiple adapters? Wouldn't it be nice to have several devices share the same 2.1mm power plug? Split your adapter's power output among several projects!
Take any 2.1mm-tipped adapter, plug this in, and then share the power between 4 devices!
Originally designed for power up strip LED projects, these powerjack splitters are an idea that has been waaay too long in coming. What an obviously handy idea!
