Turn your mouse pad into a working electronic device with the new USB Electronic Mouse Pad and Battery Free Wireless Mouse! This ingenious product provides a battery free solution for wireless mouse users. The mouse pad plugs into any USB port, which provides the power needed by the optical mouse to operate wirelessly. Review: "The mouse derives its energy from the accompanying mouse pad, using
electromagnetic induction to convert the pad’s local electric field into
current. Consequently, the mouse can’t stray from the pad, which is
itself powered through a 1.5m USB cable. The pad also houses the
receiver for the mouse’s RF signal, and A4Tech boasts that 100 NB-30
mice can be used in a room without any interference. The mouse is
short on frills – no navigation buttons, for example – but has a
comfortable scroll wheel. Extended use allayed our initial fears that
the 155 x 205mm pad might prove too small. Also, though the optical
sensor’s resolution is quoted at only 670dpi (800dpi is the norm), we
found no precision problems – even when gaming. The electrical
field precludes use on metal desks or within 20cm of CRTs, and the 1.5m
cable for the pad may be too short for floor-bound tower systems. But
the NB-30 offers freedom not only from wires but from batteries too." This unit is NEW IN BOX. The tape holding it closed did break so I opened only to inspect and photograph it. Any scuffs you see in the pictures are cosmetic on the box itself or the internal plastic housing, NOT on the actual unit. It has never been taken out of the internal plastic shell.
