Well, we all loved Regen’s Renu solar-powered iPod dock, but this guy pictured above towers over it. It’s called the Reverb and it’s 3-feet tall, living solely to crank out 60 watts of power using the power of the sun.

This bad boy will play your music for 4.5 hours at full volume or 12 hours at a normal volume. BUT, it takes 20 hours of outdoor sun exposure (or 40 hours indoor) to get a full charge. If you are not the patient type, the Reverb can be powered using a regular electrical socket.

Sure, there are plenty of solar powered chargers to charge your gadgets, but few are as sexy or as versatile as the forthcoming Regen ReNu. The solar panel is used along with one of several optional bases. These include an iPod/iPhone dock, a sound dock with it’s own speakers, and an LED desk lamp.

The built in battery constantly stores juice even when your iPod isn’t docked, so that the ReNu can then transfer the charge into your device. It can even pull power from a wall socket if you don’t have light in your space.

Sanyo’s line of Eneloop batteries are as green a battery as you will find and they have some more improvements to make them even more Earth friendly. These newly upgraded Eneloops can be recharged around 1,500 times, which is said to be a new record for the industry.

The batteries come pre-charged from the factory using clean energy from renewable solar power. If we had to guess, we would say that the other big names in batteries are watching very closely indeed.

Solar power has come a long way. They used to be something you only saw on hippie communes and Sci-fi movies. Solar panels are on everything now, especially our charging gadgets. The latest to sport a solar panel is the Surge iPod Touch charger, which allows you to recharge your iPod Touch anywhere, as long as you have sunlight.

The case features a 3.7 V lithium-ion battery that can be charged via the sun or by USB should it be cloudy. It comes in a bunch of colors. We aren’t sure if they have chargers for the other iPods, but at least your Touch is covered.

Solar Technology’s CamCaddy universal camera charger is already available in a bundle with the company’s Freeloader Pro solar charger, but now it’s available by itself. The charger isn’t 100% “universal”, but the company says it should be compatible with over 85% of the proprietary batteries used in digital cameras, camcorders and DSLRs, and if you are unsure, just check their website before you buy.

The charger is also of course still fully compatible with the Freeloader and Freeloader Pro, and it comes with a car adapter, a USB charging cable, and US and Euro plug adapters so you should be covered.

The ideal phone would never have to be plugged in or at least would need to be plugged in only rarely. The reality today is that high-end devices like the iPhone burn lots of battery power and require almost daily charging to remain usable.

A company called MotionTouch has announced a new charger for the iPhone that is eco-friendly and charges by light. The device has a solar cell on the back of the sleeve that can gather power from some ambient lighting and from the sun.

Hot on the heels of Wildcharge’s induction pad, Energizer is partnering with XPAL Power to expand its Energi to Go line of portable battery packs.

These newly branded chargers run the gamut from an iPhone 3G or #G S battery sleeve to a couple of solar chargers to a larger lithium ion charger that can power up to three devices simultaneously even a laptop. Many of the battery packs are available already under the XPAL brand but the ones with the new packages will be available very soon in stores.

Samsung’s upcoming Blue Earth smartphone is a little different. In front you’ll find a touch screen, while the entire back takes advantage of the space with a solar panel. If you can believe Samsung, they are claiming that the panel produces enough electricity to place a call any time you need to.

We’ll believe that one when we see it, but as far as eco-phones go, this one is interesting. Keeping energy in mind, the phone includes an Eco Mode, which adjusts screen brightness and deactivates Bluetooth. Not only that, but most of the phone is made from recycled water bottles. Both the handset, and it’s charger are free from harmful substances.

Energizer’s Solar Recharger looks like an odd device. It looks like it could be an iPod battery extender, a AA charger or even a Solar adapter. And it actually is all of the above. Mainly, it’s a battery charger for standard rechargeable AA and AAA batteries and is primarily powered by an AC jack that’s assisted by a flip-out solar panel. The USB port can power your connected gadget and the Solar Charger will act as an extended battery for almost any USB-powered device, like your iPod for instance.

The beauty of this device is that through the use of cheap rechargeable batteries, Energizer sell it for just $50, with 2 AAs included. Some other features include weatherproofing and a rotating solar panel.

One of the worst things that can happen to a traveling geek/businessperson is to have their gadgets run down before the day is done. Power for your cell phone, MP3 player, or GPS device can be at a premium some days. A new messenger bag from Eclipse gives you a place to store all your gear and can help keep the gear charged at the same time.

The Fusion Solar Messenger bag can charge cell phones, MP3 players, and rechargeable batteries or any other device that can be plugged into a 12V auto adapter. The solar charger itself is removable and can be used outside the bag.

If there is one universal thing cell phone users can agree on it is longer battery life for their devices. We have seen all sorts of methods to prolong the run time of our cell phones from add on batteries to solar chargers.

The SunBlazer is a pretty interesting product and combines two things that most cell phone users might need. The SunBlazer is a holster for your cell phone that also has a solar charger built-in to keep your phone powered up.

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.

Better Energy Systems, the company behind the eco-friendly Solio Classic hybrid (solar/wall socket) handheld electronics charger, is at CES with a new charger it says packs almost double the power of the original. It’s called the Solio Magnesium and it is being priced at around $200.

The Solio Magnesium is capable of fully charging a cell phone approximately three times. It “combines efficient solar cells, a powerful internal battery, and a rugged, environmentally friendly magnesium alloy shell.” Compatibility exists with the iGo tip system for supporting the charging of multiple types of devices and includes a female USB for an iPod.
