Good looking cable adapter at a good price ($8.99 at time of review) for two people if you don't want to make them yourself. But the description of the keg jack size is wrong. The "2.1mm" center pin is too big to fit into the Netgear power adapter I was hoping to use to power my LiPo charger. If you look at the diameter, it's closer to 2.5mm and looks a lot bigger than the bulky screw terminal connector that fits the Netgear power supply. This cable adapter fits my Asus PA-1900-30 power supply with 5.5mm x 2.5mm plug.
