ABSTRACT:
A device for testing the operability of an AC power outlet, a DC power outlet and A/V input jacks may include an AC test circuit, a DC test circuit, an A/V test circuit, a logic circuit, and a system OK indicator. At least the AC test circuit and the DC test circuit may be operatively connected to the logic circuit such that when at least the AC plug and the DC plug are inserted in a functioning power outlets, the system OK indicator is activated.
