<p>A USB converter adaptor for a mobility assistive device includes a mobility assistive device connector (3), a DC-to-DC converter (4) and a USB connector (5). The mobility assistive device connector (3) includes a tubular casing (33) and two conductive pins (31) that are disposed in the tubular casing (33) and that are adapted to be coupled to a charging connector of the mobility assistive device so as to be electrically connected to a battery of the mobility assistive device for drawing the battery power from the battery. The DC-to-DC converter (4) is electrically coupled to the mobility assistive device connector (3) for converting the battery power into an output power that has a predetermined voltage value. The USB connector (5) is electrically and fixedly coupled to the DC-to-DC converter (4) for outputting the output power.</p> |
