Purkeys, in partnership with Maxwell Technologies, has introduced a portable jump starter called CAPS that's designed for commercial vehicle applications.

The portable jump starter uses an ultracapacitor to provide power instead of batteries, gas-powered engines or generators. CAPS can charge, discharge and recharge faster than a lead-acid battery powered jump starter and is lighter and more portable, according to Purkeys.

The device uses Maxwell’s ultracapacitor-based Engine Start Module to provide a burst of power and is combined with Purkeys smart control electronics. The ESM provides the power to jumpstart an engine, but the "smart control" electronics allow the device to be safe while still offering lighter weight and a smaller size.

CAPS can provide power to start a Class 3-8 diesel engine in local delivery and vocational applications.
