The size of a connector is related to the amount of current it has to carry. That will set the minimum size of any inline connecter. If you use 3 inline, single conductor, quick disconnect connectors and stager them, the total size shouldn’t be more than 1¼ times the diameter of the original power cable at any one point. Granted, you are still removing and reconnecting the standard plug on one of the power cable but, at least it can be a tool-less operation.
