Portable battery booster
First Claim
1. A handheld battery booster for boosting a motor vehicle having a vehicle battery, the handheld battery booster comprising:
- a handheld housing defining a chamber, wherein the housing is sized for handheld use;
a lithium battery positioned within said chamber to supply a starter current, wherein said lithium battery is a lithium iron phosphate battery or a lithium-polymer battery;
a pair of cables to transfer the starter current from said lithium battery to said motor vehicle; and
a processor operatively coupled with an ignition detection circuit,wherein the ignition detection circuit is configured to detect an ignition condition of said motor vehicle via said pair of cables, andwherein the processor is configured to prevent transfer of the starter current from said lithium battery to said vehicle battery until the ignition detection circuit detects the ignition condition.

Abstract
A portable battery booster for providing a compact, light, and energy efficient battery to jump start a vehicle. The portable battery booster generally includes a housing, a battery means adapted to be received by the housing, a pair of cable means, each of the cable means having a proximal end and a distal end, the proximal end electrically connected to the battery means and the distal end detachably connected to a discharged battery of the vehicle. The battery is generally comprised of one or more batteries having the type of primary lithium-metal, rechargeable lithium-ion, and/or lithium-polymer and more specifically preferably comprised of lithium iron phosphate for fast charging, small size, and high performance. The battery may also be connected to one or more supercapacitors, an internal CPU, DC/DC converter, etc. to increase performance. The cable means includes jaws that detachably connect to the housing in a flush and sleek manner.
