A vehicle mounted adaptor is arranged to be coupled to a portable transceiver when the portable transceiver is used within the passenger compartment of the vehicle. The portable transceiver includes a main battery, a backup battery and a power switch circuit. The power switch circuit is supplied with power from either one of said main and backup batteries and generates a control signal when turned on for operating the portable transceiver. The adaptor includes a power switch which is coupled to a car battery mounted on the vehicle. The power switch of the adaptor is switched from an OFF position to an ON position when the control signal is generated and switched from the ON position to the OFF position when the control signal is terminated. The adaptor further includes a backup battery charger which is coupled to the power switch. The backup battery charger serves to charge the backup battery when the power switch of the adaptor is in the OFF position. Therefore, the backup battery charger is able to charge the backup battery even if the portable transceiver fails to generate the control signal due to a discharged condition of both the main and backup batteries.
