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.

L'invention concerne un dispositif portatif (10) à alimentation en énergie (12) améliorée, avec à la fois une source de faible puissance, en parallèle avec une source de forte puissance provenant d'ultra-condensateurs (14). L'énergie de l'ultra-condensateur (14) est utilisée par le moteur du dispositif (18) lors de certaines périodes de pointe, qui requièrent une forte puissance du moteur du dispositif. L'invention concerne un coupe-tube portatif amélioré, à la fois avec et sans système d'alimentation en énergie amélioré (12) et comprend un système de porte-lames rotatif (24) avec un système de rouleaux ajustables (34) permettant des coupes de tubes de meilleure qualité.
