<p>The present invention is directed to a charging-cable (500, 500') comprising a charger-connector for connecting the charging-cable arrangement (500, 500') to a mating USB connector in a charger, and a device-connector for connecting the charging-cable (500, 500') to a portable device (10). The charger-connector comprises USB-terminals arranged so that a first USB-terminal can connect to the VBUS signal, a second USB-terminal can connect to the D-signal, a third USB-terminal can connect to the D+ signal and a fourth USB-terminal can connect to the ground signal of a USB connector; and wherein the device-connector comprises device-terminals arranged to be operatively connected to said portable device (10) so that a first device-terminal connects to a ground terminal and a second device-terminal connects to a charging terminal of said portable device (10). Moreover, the first USB-terminal is connected to one of the second or third USB-terminals via a first circuit (510, 510') so that the first USB-terminal can be operatively connected to the other of said second or third USB-terminals when the charger-connector is connected to an external charger comprising a second circuit (520) that connects the second USB-terminal to the third USB-terminal. Furthermore, said other of the second or third USB-terminals is connected to the second device-terminal via a third circuit (530, 530') so that the first USB-terminal can be operatively connected to the charging terminal of the portable device (10) via said first, second and third circuits (510, 510', 520, 520', 530, 530').</p> |
