M2E Developing Kinetic Cellphone Charger That is Up to 700 Percent More Effective

This isn't the first time we have seen a cellphone charger that is powered by kinetic energy, but the difference is that M2E is working on a charger that can produce 300 to 700% more juice than current technologies. They hope this will translate into a full-on replacement for cellphone batteries somewhere down the line. According to earth2tech, M2E's short term goal is to develop a charger that will produce an hour of talk time for around six hours of normal movement. Currently, M2E is in talks with major accessories manufacturers about bringing a device to market as early as 2009. [earth2tech via Inhabitat]

Brando's Mini Universal Battery Charger is Jawsome, USB-Powered

Brando has a new universal battery charger available, working on the same jaw-grip/adjustable electric contacts principle as Thanko's version before. This time though, the gizmo is designed to be portable and draw its power from a USB source and it's got "high capability switch power supply with efficient transforming." It's even keyring mountable. So if you're constantly charging up a variety of batteries for all your gear, and don't fancy hauling all the power bricks around this might be an elegant solution. Can be yours now, for $12. [Brando]

Six-Bay MacBook and iBook Charger Is An Orgy Of Charging

Oncore's just released a six-bay MacBook and iBook charger which, as its name implies, can charge six batteries at the same time. Or rather three batteries at the same time, since it's divided up into three sets of two charging bays. Each bay can charge one while holding onto the other for when the first is done. This is made for the "education" market, but is perfect for when we need to go in the field and liveblog an Apple event and have to have six batteries on us. Comes in just charger or charger + six pack battery configurations. [Oncore via Macworld]

FastMac U-Charge is the First Universal External Apple Laptop Battery Charger

We've reviewed MacBook and MacBook Pro battery chargers before, but the problem with that is that they aren't compatible between different laptop types. Not so with FastMac's U-Charge. Their external battery charger lets you juice up MacBook Pro (15 and 17-inch), MacBook, PowerBook G4, iBook and even PowerBook G3 batteries externally all from the same unit. More »

Brando's Jaw-Tastic Solar Charger Will Power All Your Gizmos

This mashup from Brando takes some of Thanko's electric vampire universal charger idea and the "survival" solar charger and mixes them into one multi-purpose device. Its adjustable contact teeth mean its jaw can grab onto and charge a wide range of batteries, it's got a set of adaptors to suit different cellphones and has a USB output for your iPod and the like. Better yet, you can charge up its 1,350 mAh internal battery up by sunlight, USB or AC adapter. Basically you'll never be without a source of power for your gadgets. And it's got an LED torch. Is there a better power gizmo out there? [Brando]

Freeloader USB Battery Charger Supposedly World's Smallest

This new gizmo will charge a pair of your AA or AAA NiMH/NiCad batteries in three to four hours of slurping power from a USB socket, no power brick required. It's also apparently the "smallest and lightest" in the world. That may or may not be true, but it certainly is small enough to slip into your laptop case and not worry about. It's even rubberized to make it a bit tougher for portability, so if you're the type who needs AA batteries out in the field, it might be useful. Available now, for $25. [Geek Alerts]

Thanko Charger Bracelet Has More Wrist Power Than The Hulk

Of all the crazy thing's Thanko's come up with, this USB charger bracelet's probably the least crazy. Instead of having a separate charger that you have to keep close to a PSP, DS Lite or a cellphone by putting both onto a table, this wrist charger lets you wear the power on your person and play/talk like you normally would. It charges from USB in approximately 4 hours and gives 22.5-28.5 hours on the DS Lite (lowest brightness) and 3.5-4.5 hours on the PSP. [Thanko]

Design: Kineticel, the Human Powered Battery Charger

One of the ideas submitted to the Next Generation competition featured in Metropolis Magazine was this Kinetic Energy-harnessing battery charger by Yael Miller. The concept is to take something we're already doing—such as working out, flopping around in a baby rocker, vacuuming, or flushing the toilet—add the piezoelectric effect, and come out with batteries that are charged by "human power." Imagine all the television remotes we could power just from flushing our droppings. [Reuben Miller via Oh Gizmo via Boing Boing Gadgets]
