A system for powering a peripheral device with a host device is described. The system comprises N host interface power ports, each adapted for coupling to a corresponding host port on the host device to deliver power to the peripheral device. A current adding unit adds current received from the host device via at least the N host interface power ports to produce a total current. A power terminal is coupled to the peripheral device to send the total current from the current adding unit to the peripheral device.

La présente invention décrit un système d'alimentation d'un périphérique avec un appareil hôte. Le système comprend N points d'alimentation d'interface hôte, chacun étant adapté pour être relié à un point d'alimentation hôte correspondant sur l'appareil hôte pour alimenter le périphérique en courant. Une unité d'addition ajoute le courant reçu de l'appareil hôte par au moins le biais des points N d'alimentation d'interface hôte pour produire une valeur de courant totale. Une borne d'alimentation est reliée au périphérique pour envoyer le courant total de l'unité d'addition de courant au périphérique.
