POWERED HAND HELD DEVICES

摘要

A powered hand held device (10) having an improved power (12) supply with both a low power source in parallel with a high power source from ultracapacitors (14). The ultracapacitor (14) power is used by the device motor (18) during certain peak power demands which require high power to the device motor. An improved hand held tube cutter tool (10) is provided both with and without the improved power arrangement (12), and includes a rotating cutter head assembly (24) with an adjustable roller assembly (34) providing a superior tube cut.
