A4Tech has come up with a battery-free wireless mouse that does away with the need to replace batteries or recharging, since it receives power from its mouse pad courtesy of “electromagnetic induction technology”. While the idea certainly isn’t new, at least you no longer need to worry about packing extra batteries whenever you go off on a long road trip. Function-wise, this offering from A4Tech isn’t jaw-dropping, boasting a standard optical resolution as well as dual scroll wheels for horizontal and vertical scrolling. This nifty little traveling companion retails for $22.99 – at that price, it certainly sounds as though it is worth a try.
