The robust KMB-35 multi-charging adapter made of metal features a built-in switching power supply with hollow connectors that provide the necessary operating voltage to up to six charging bays. This allows for the simultaneous charging of up to 6 radios. Simply place the existing KSC-35 charging bays or the separately ordered KSC-35SCR charging bays in the KMB-35, secure them using the central holding rail, connect the power cable, and your charging station is ready for use.
