New, Battery-Free Genius DX Eco Wireless Mouse Is Very Light

Genius decided it was time someone actually circumvented a certain issue that wireless mice have been wrestling with, that of weight.

As technology reduces its reliance on cables more and more, it has to deal with other issues, like peripheral bulkiness.

Wireless mice are, one might say, notorious for being big and heavy compared to their regular counterparts.

The blame for this lies, for the most part, with the AA or AAA batteries that are used to make them work.

Genius decided to completely do away with batteries, choosing a light, gold capacitor that fills the same role.

As such, the total weight is of only 95 grams and the whole thing measures 110 x 73 x 35 mm (4.33 x 2.87 x 1.37 inches).

DX Eco, as the mouse is called, utilizes the 2.4 GHz wireless band (it relies on a USB receiver, plugged inside the PC).

Normally, this would leave it open to radio interference, but the company assures its customers that a proprietary technology prevents this.

Meanwhile, the maximum sensitivity of the optical sensor is 1,600 DPI, adjustable to 800 DPI.

At the lower setting, the mouse will consume less of the capacitor's power.

Speaking of the capacitor, it should be able to last for about a week before needing a recharge, and it is here that things get interesting: all it takes for the full charge to be restored is three minutes.

The company says the gold capacitor “expand[s] rechargeable life up to 100,000 times.”

Other features include a rubberized top side, three main buttons, four extra buttons, the BlueEye technology and a 2-way scroll wheel.

The price is of US 49.99, or 37.04 Euro. A three-year warranty is included in the offer.

We actually wrote about this mouse back in September, but only now has it become available in online stores (or soon will, depending on how fast your region's retailers are).
