Abstract: A tactical power adaptor is provided which adapts power from worldwide power sources and supplies the power to a plurality of electronic devices. A power input provides uninterruptable power to the adaptor to ensure that the input power does not interrupt the electronic device if the source is interrupted. A converter converts the input power from the worldwide sources to a power manageable by the adaptor. A plurality of connectors each supply a different variable voltage. A voltage varying circuit allows an operator to vary a voltage of the connectors and a channel selector selects between the connectors. Power switching modules supply the correct amount of power to a corresponding connector according to the voltage set by said voltage varying circuit.
