Yes, yet another useless USB powered gizmo. I’m starting to think it’s a trend to invent utterly crappy devices and launch them on the market.

After reviewing so many USB powered gadgets that had absolutely no meaningful use ( USB powered desktop fan, USB powered desktop speakers and a USB powered outdoor thermometer - and some other, just use the search box and enter usb powered), I’ve got to say this one’s the closest to having a real purpose.

This can shaped device is meant to freshen the air around you and allow you to breath clean O₂ rich air.

When you absolutely, positively can’t find anything else to do with $24.99, the “Portable Can Shape USB Office Home Miniature Anion Humidifier” is there.

Any self respecting geek should own such a toy - it looks pretty coolish, although the green is a bit flashy, you’ll have something too cool you of during the hot summer days. And that’s not all, if you’re still not satisfied you’d be more than happy to find out this desk fan also doubles up as an usb hub - a 4 port one.

For $15 you’ll get this small fan that re-circulates the air ( and probably dusts off your desk as well ), a 4 port USB hub and an ON/OFF switch to shutdown the fan when you’re don’t need it. Also comes with 4 pieces of anti-dust stoppers that keep the dust away and other damages.

Yesterday, Kensington announced the launch of it’s latest product, the Wireless USB dock - no more pesky cables to mess with from now on.

Even more, Kensington apparently decided to give this device a DVI output to sweeten the deal even more. The DVI device can output video signals of up to 1680×1050 which are standard resolutions for most 20-22″ monitors. Besides the DVI, the Wireless USB dock features 5 USB ports and a stereo mini jack for external speakers.

According to Kensington, you could also use an external HDD with it and everything would run smooth. It currently supports Vista and XP but according to Kensington it should support any wireless compatible PC.

The device has been announced to ship by the end of the month through Kensington’s own shop and will priced at $230.

No, they’re not some fancy luxurious over-priced speakers - they’re just some plain 1W USB 2.0 powered speakers priced at a mere $39.99. That’s all there is to it unfortunately. Besides the cool aspect don’t expect too much out of these speakers as they’re rated at only 1W per channel.

They’re compatible with almost every OS - meaning no drivers required - except Linux.

Here’s a breakdown of the tech specs according to ThinkGeek :

• Small USB speakers that produce quality audio output
• Rated at 1 Watt per channel
• USB 2.0 compatible
• USB HID spec. v.1.11
• Compatible with Windows98SE/ME/2000/XP and Mac 9.x (no drivers required)
• Dimensions: 1.6″ x 2.1″ x 3.5″ (4 x 5.4 x 9cm)

Here’s another useless way to spend $22 - buy a USB powered pole dancer. The pole dancer performs as you type and it includes software that features a daily word count, your top five typing performances and a WPM testing function. Although it would be a rather lame excuse to pretend this USB powered toy can increase your efficiency, we say why not give it a shot ? It will certainly stylize your office and draw more curious eyes towards it.
