Genius Intros Wireless Mouse Without a Battery

You still need to charge the mouse, but the design enables the DX-Eco model to be fully charged within three minutes. The downside: you will have to recharge the mouse every day.

For about $40, you get an otherwise common mouse that works via a 2.4 GHz connection and a distance of up to 45 feet between the sender and receiver. The manufacturer says that the DX-Eco works on surfaces such as dusted glass, marble, carpet, sofa, delivers a resolution of 800 or 1600 dpi and integrates seven buttons. The mouse works with Windows XP/Vista/7 as well as Mac OS X 10.4 and higher.

Genius says that the gold-capacitor can be recharged up to 100,000 times.

    shuffman37I don't see a practical reason for using a capacitor and the high price when the mouse will be dead long before the cap dies from cycling. .


    The global destruction caused by the production of batteries is becoming quite bad. While gold mining can be somewhat as bad, the consequences of batteries over time is significantly worse. 40$ for a mouse isn't a high price for what you are getting out of it and the money you save by not having to use batteries. Your argument against this seems to be that you are too lazy to charge it every day so you dismiss it as being expensive, low quality, and unreliable which i find ridiculous.

    Make it a gaming-grade mouse and I'm in.

    Capacitors may suck to have to recharge; sure, you have to put the mouse on its dock at the end of the day- but you do that with a battery-powered mouse anyways!

    With a capacitor, 3 minutes gets you, say, 6 hours of use.
    With rechargeable batteries, 3 minutes gets you 2 minutes of use (better mice unfortunately use propietary batteries).

    Plus, you don't have to buy replacement packs when those rechargeable batteries die, and the mouse pays for itself if you're talking alkaline batteries.

    Even if you're too lazy or forget to charge the mouse 3 minutes is about the time it takes for you to put the mouse on the cradle, hit the power switch, and by the time your desktop is useable so is your mouse.

    This is a beautiful idea.

    OK here's an idea. we've all seen the power mat right? allows you to charge your device wirelessly etc etc... WHY DONT WE DO THAT FOR MICE? Put a spiral of copper around the base of the mouse, plug that ring into the board to power the mouse (or more realistically the caps) then plug your mouse pad into the wall and be done with it.

    I don't see a practical reason for using a capacitor and the high price when the mouse will be dead long before the cap dies from cycling. I've had my Logitech K800 and M305 mouse for over a year. The k800 using the original batteries will still last about 4-5 days between charges with heavy usage and backlight on. The mouse uses disposable AA and I have to change one about every 20 days (could get a rechargeable battery, but new batteries are still cheap and reliable).

    How about high quality products with lower energy usage, that'll make me happy. Batteries tend to be the most reliable part of most gadgets these days, sigh. I'd rather have a $40 mouse thats tough with a replaceable battery of the user's choice. When my k800's rech. AAs die I'll just get a new set and enjoy for another few years.
