Abstract

A portable charger is capable of jump starting a 12V car battery as well as charging 5V portable electronic devices. The charger includes a charger battery; a power supply operatively connected with the charger battery; at least one USB output jack operatively connected with the power supply for providing +5V USB power; and positive and negative jumper cable jacks operatively connected with the power supply for providing +12 V DC power to jump start a vehicle battery.

Claims

1. A portable charger capable of jump starting a 12V car battery as well as charging 5V portable electronic devices, comprising:

a charger battery;

a power supply operatively connected with the charger battery;

at least one USB output jack operatively connected with the power supply for providing +5V USB power; and

positive and negative jumper cable jacks of different shapes and operatively connected with the power supply for providing +12 V DC power to jump start a vehicle battery.

2. The portable charger of claim 1 further comprising a +14 V DC input jack for recharging the charger battery.

3. The portable charger of claim 1 further comprising a floodlight.

4. The portable charger of claim 1 further comprising a safety circuit operatively connected with the power supply for enabling or disabling the jumper cable jacks responsive to sensed conditions.

5. The portable charger of claim 4 further comprising a jump start button that is pressed to activate the safety circuit in a jump start safety check sequence, a first light of a first color that is arranged to illuminate the jump start button and a second light of a second color that is arranged to illuminate the jump start button, wherein the safety circuit causes the first light to illuminate in case the safety circuit disables the jumper cable jacks, or causes the second light to illuminate in case the safety circuit enables the jumper cable jacks.

6. The portable charger of claim 5 wherein upon successful completion of the jump start safety check sequence the portable charger remains ready to provide 12 V DC current during a pre-determined period of time.

7. The portable charger of claim 6 wherein during the pre-determined period of time the portable charger provides 12 V DC current from the charger battery to the charger jacks in response to a second user actuation of the jump start button.

8. The portable charger of claim 6 wherein the pre-determined period of time is sufficient for three discrete jump start attempts.

9. The portable charger of claim 6 wherein the portable charger discontinues readiness after three discrete jump start attempts.

10. The portable charger of claim 5 further comprising a power button that is pressed to activate the portable charger for use, and a third light of a third color that is arranged to illuminate the power button, wherein the third light is illuminated steadily while the portable charger is active, and the safety circuit causes the third light to blink in case of an over current condition.

11. The portable charger of claim 1 further comprising a power button that is pressed to activate the portable charger for use, and a jump start button that is pressed to activate the portable charger for jump starting a vehicle battery.

12. The portable charger of claim 1 wherein the power button is illuminated in a first color when the portable charger is activated for use, and the jump start button is illuminated in a second color when the portable charger is activated for jump starting a vehicle battery.

13. The portable charger of claim 12 wherein the jump start button is illuminated in a third color in case a fault condition is detected when the jump start button is pressed.

14. The portable charger of claim 1 wherein the charger battery is a lithium ion type battery.

15. The portable charger of claim 14 wherein the charger battery is of at least 57720 mWh capacity.

16. The portable charger of claim 1 further comprising a case containing the other components.

17. The portable charger of claim 16 wherein the portable charger is less than 30 cm along any edge of its case.

18. A portable charger capable of jump starting a 12V car battery as well as charging 5V portable electronic devices, comprising:

a charger battery;

a power supply operatively connected with the charger battery;

at least one USB output jack operatively connected with the power supply for providing +5V USB power;

positive and negative jumper cable jacks operatively connected with the power supply for providing +12 V DC power to jump start a vehicle battery; and

a case housing the other components, wherein the case is less than 30 cm along any edge.

19. A portable charger capable of jump starting a 12V car battery as well as charging 5V portable electronic devices, comprising:

a charger battery rated at 11.1 V DC;

a power supply operatively connected with the charger battery;

at least one USB output jack operatively connected with the power supply for providing +5V USB power;

positive and negative jumper cable jacks operatively connected with the power supply for providing +12 V DC power to jump start a vehicle battery;

a safety circuit operatively connected with the power supply for enabling or disabling the jumper cable jacks responsive to sensed conditions; and

a microprocessor configured to interoperate with the safety circuit and to track the capacity level of the charger battery.

20. The portable charger of claim 19 further comprising a jump start button that is pressed to activate the portable charger for jump starting a vehicle battery, wherein the jump start button activates the safety circuit to enable or disable a jump start relay for permitting the portable charger to jump start the vehicle battery.
