1. A portable charger capable of outputting power through both direct and wireless connections, comprising:
a charger battery disposed within a charger housing, said charger housing defining at least one mounting surface adapted for receiving a portable electronic device in an abutting manner;
an AC inverter circuit operatively electrically connected with the charger battery and with a wireless transmitter;
a jump start circuit operatively electrically connected with the charger battery and with an ignition power outlet, said ignition power outlet comprising a positive power socket and a negative power socket respectively associated with a positive jumper cable jack and a negative jumper cable jack; and
a microcontroller configured to establish or interrupt the operative electrical connections of the AC inverter circuit and the jump start circuit with the ignition power outlet in response to system parameters measured by a safety circuit in operative communication with the microcontroller,
said safety circuit comprising:
a voltage input analyzer to measure voltage across the positive and negative jumper cable jacks;
a reverse current protector including an operational amplifier operatively connected to a negative terminal of the charger battery to determine if the positive and negative jumper cable jacks are properly connected to a battery in need of a recharge based on the detection of a reverse current across the operational amplifier; and
a reverse polarity detector to measure the polarity across the positive and negative jumper cable jacks,
wherein the portable charger is capable of wireless outputting power to a portable electronic device when said portable electronic device is positioned on the mounting surface of the charger housing.
