A4Tech’s Optical Mouse Needs No Batteries

We’re going to have to start the day by apologizing for the lateness of the updates. Miscommunication, etc. You don’t care, but there you have it.

Anyway, here we have a funky Korean mouse from A4Tech that performs a little bit of electromagnetic magic by not needing a battery. At all. Instead, it’s kept alive through a special USB mouse pad and the wonders of electromagnetic induction. It’s optical, and has a resolution of 800dpi. Aside from that… it’s pretty much just a mouse. You’ll just never need to change the batteries, which is kind of nice.

Given that it does something fairly useful, we’re surprised to hear of the price: 20,000 Korean Won, about $21. Of course, it’s likely to be available in Korea only.
