We all hate buying batteries and if you’ve bought Wii Fit, chances are you and your enormous love handles are going to go through many batteries. Luckily for you, Nyko has a solution in the form of their new Energy Pak for the balance board.

The Pak installs on the bottom of the board, making it easy to plug in and recharge without having to take the device out or turn the board over. Because God forbid you burn the 1 or 2 calories it would take to turn the board over. You can get yours starting May 19th for $19.99. Now get to work tubby.

I’d like to officially say that this device is the last egg straw. There seems to be an overabundance of egg themed gadgets lately, and I think we might be abusing the whole egg thing. There’s the egg phone, wobbly egg speakers, even the egg mouse to name just a few. You gadget creators are driving me crazy with the eggs already!

Now for the latest…egg. The Egg Speaker Charger Concept device functions as a pair of satellite speakers when ‘hatched’ open, with its base functioning as a subwoofer. The base will also double as a dock for a compatible MP3 player, charging your device through induction.

When you’re hell-bent on world domination, getting your hooks into little girls and hypnotizing those who love pink, then feeding them a steady diet of more pink cuteness, you want to harness an energy source that’s never ending. Like the sun. Once you do that, there will be no stopping you.

That’s why your pink feline overlord has given you this device. The Hello Kitty Solar-Power Charger can juice up almost any handheld device, whether it’s a phone, media player, or camera. And even if there is no sun, the charger can still be plugged into a DC outlet for up to six hours of power on the go.

The Ravi solar charger hopes to steer you toward greener living with it’s attractive flower-like design. The Ravi solar has photovoltaic arrays attached to petal extensions. The flower aspect is not just symbolic, it actually absorbs energy from the sun during the day, storing it in an internal battery. It gets some points for coolness due to the fact that the petals glow once the battery is charged. At night, you would have a kick-ass glowing garden. You would then remove the battery packs to power all of your home appliances.

The idea is that with gardens of Ravi portable solar generators in a neighborhood, enough power could be generated to supply the community, and if that can not be managed, it would at least lessen energy needs. It’s a pretty cool idea, but it has a kind of War Of The World quality that scares me.

Here’s another great gadget for those who are environmentally conscious. The Strapya mini solar cell phone charger is smaller than an iPod, and when it has 6-10 hours of sunlight it becomes a dependable backup power source for your cell phone.

It hooks up to your phone using an adapter and you can get 3 hours of energy. Not only is it useful and environmentally friendly, but the price is not outrageous at about $17.54. So it wont “Strapya” for cash. And hey, sunlight is free.
