Why buy rechargables when you can get more juice from regular alkaline batteries? You can put your regular batteries into a battery recharger and treat them just like rechargable batteries. WattsClever has released an alkaline battery charger that allows you to do just that.

The charger uses a “microprocessor to minutely control the trickle charge so the batteries don’t overheat and die.” We aren’t sure how long the recharged batteries will last, or how many times you can recharge them, but it’s a good alternative to buying expensive rechargables. This charger also works with Ni-Cd or Ni-MH rechargeable batteries, so you are covered no matter what you use. The WattsClever alkaline battery charger will cost you $46.

After a full day of shedding pounds with the Wii Fit and several rounds of Punch-Out, you’ll want to recharge your balance board. Mad Catz’ upcoming Power Up Charging Station will take care of you and get you back in the game in no time.

The stand comes bundled with a special, contact-charging battery that replaces the standard AAs. Just load the battery into the board, the board into the stand, and your Balance Board recharges. Mad Catz also integrated two USB ports into the stand’s body, to charge your other gear. A foot pedal releases your board.

Chances are you have quite a few spent AA batteries lying around. Probably because you played with your WowWee robots too much. Well, here’s an interesting concept for quick and easy re-charging of all your AA batteries.

The Febot is a design by Ji-yun Kim, Soon-young Yang and Hwan-ju Jeon out of Korea. It would be suction mounted to your window so it can catch the breeze and recharge your single AA inside. A pretty interesting solution. I have a feeling it may take a while though, unless you are in a hurricane.

Chances are you’ve reached for your flashlight in an emergency, only to find that the batteries have died. LED flashlights aren’t much better, as they take hours to get a full charge. The Light For Life UC3.400 flashlight from 5.11 Tactical could end all of your flashlight woes for good. It doesn’t use batteries, instead it uses an ultracapacitor to hold it’s charge, which gives you about 90 minutes of light per charge. It produces 270 peak lumens in bright mode, 90 lumens in standard mode, and has a 270-lumen tactical strobe.

That’s pretty impressive, but it gets better. The ultracapacitor will go from dead to fully charged in just 90 seconds. Yes 90 seconds. For at least 50,000 times. Assuming you used a full charge every day, it’s good for 135 years. You’ll never need another flashlight. Ever.

Imagine never having to charge your phone from an outlet ever again. It sounds too good to be true, but it may happen sooner then you think. No one likes to recharge their phone every day. And after you charge it, the battery slowly loses power as you go about your day.

Thanks to motion-powered electronics, which is in development by M2E Power, you may be able to charge your phone just by walking or having it on you. M2E is claiming that their system will generate 300 to 700 percent more power than currently available kinetic energy technologies. So one day soon charging your phone by plugging it in may be a thing of the past.
