The new 12V Jump Starter with Air Compressor, Model No. JNC550A, from Jump-N-Cary offers powerful jump starting capability plus the convenience of an integrated air delivery system.

It features our exclusive Core PROFORMER battery technology, designed to provide extreme starting power, extended cranking duration, numerous jumps per charge and a long service life. It also is a great power delivery system, able to power 12V accessories via its DC power port, as well as small electronics via its USB port. Plus, with automatic charging from a built-in charger, extra long cables, a powerful work light and a rubberized base that won’t scratch vehicle surfaces, the JNC550A is as convenient as it is powerful. Its air deliver system features high CFMs to fill most passenger vehicle tires quickly and easily, an integrated gauge for confident top offs and a 24" long air hose with simple chuck for easy tire connections.
