A modular device charging station connectible to a power source through a cable includes an input endcap defining a power connector slot and a plurality of input locator pins in a predefined layout. A cradle body is defined by a device receptacle, with an input side having a power connector socket connectible to the cable and defining one or more input side locator holes receptively engageable with the input locator pins. An output side A pass-through power connector plug and a plurality of output locator pins in the predefined layout are on an output side. A terminating endcap defines a plug pocket and a plurality of terminating-side locator holes in the predefined layout receptively engageable with the output locator pins. A charging circuit with a power signal input is connected to the power connector socket, and the pass-through power connector plug is electrically connected to the power connector socket.
