Abstract

The multiple unit portable battery charger disclosed is a portable, rechargeable refueling station for handheld and mobile electronics. The multiple device portable battery charger is capable of providing a full charge to two electronic devices either simultaneously or individually. Additionally, the battery charger can charge the two devices simultaneously up to three separate times before the battery charger requires recharging. In other words, the battery charger disclosed is capable of charging six or more devices before needing to be recharged itself.

Claims

1. A portable electronic device battery charger, the battery charger comprising:

a housing;

a battery, the battery located within the housing;

at least three interface ports on the housing, wherein a first interface port is configured to enable charging of the battery and a second and a third interface port are configured to enable charging of a plurality of electronic devices from the battery simultaneously.

2. The battery charger of claim 1, wherein the battery is a lithium ion battery.

3. The battery charger of claim 1 wherein the second and third interface ports are configured to receive connecting devices.

4. The battery charger of claim 1, wherein the second and third interface ports are configured to receive electronic device charging adapters.

5. The batter charger of claim 4, wherein the electronic device charging adapters are configured for different electronic devices.

6. The battery charger of claim 1, wherein a sense circuit activates a charging of the electronic device.

7. The battery charger of claim 1, wherein a sense circuit deactivates charging of the electronic device.

8. The battery charger of claim 7, wherein the sense circuit senses the absence of the connection to the electronic device.

9. The battery charger of claim 1, further comprising a power level indicator.

10. The battery charger of claim 1, wherein an indicator indicates charging of an electronic device.

11. The battery charger of claim 1 further comprising a voltage regulator circuit.

12. The battery charger of claim 1 further comprising a circuit with short circuit protection.

13. The battery charger of claim 1 further comprising a circuit with reverse bias protection.

14. The battery charger of claim 1 further comprising a battery controller configured to protect the battery against battery depletion and discharge.

15. The battery charger of claim 3 further comprising a fastening mechanism to secure the connecting devices.

16. The battery charger of claim 4 further comprising a fastening mechanism to secure the charging adapters.

17. The battery charger of claim 1 wherein the electronic device being charged is capable of operating while connected to the battery charger.
