What if you had a battery that is powered on nothing but ordinary water? It is now named the Powertrekk, and it uses fuel-cell technology to convert hydrogen gas into electricity.

The secret is a thing inside the Powertrekk known as the Powertrekk Puck which holds the water and carries out the fuel based charge.

The Powertrekk is designed for USB powered devices, and you can use your USB charger on your mobile device for aiding in the charge.

I am sure that you are seeing the benefits of the PowerTrekk. I wonder if this company should use the slogan: “the last mobile charger that you will ever need to buy”.

The Powertrekk might be the answer to that age-old question for what you would have if you lived on a deserted island. Considering that I don’t need any sun or outlet, it has my vote. All I would need is a teaspoon of the water that surrounds the island. I’m not certain if I would have any cellular phone reception, but I would be entertained by a plethora of pre-loaded apps.

Of course, you will pay for this type of power, to the tune of $300. I still think that it is a good deal.

While wandering the booths at CES last week, I discovered the ePawn Arena. It uses ePawn tracking technology for a large 26 inch IPS screen, which enables you to place game pieces for a very interesting gaming experience.

The demonstration showed an iPhone plugged into this thing, and the user could play a game using physical markers like chess pieces. The touchscreen seemed to know where these pieces were, and it creates a rather interesting environment for gaming.

The ePawn Arena is designed to link to smartphone, tablet, or PC and can be used for role-playing games and board games. This isn’t the first time that I have seen board games mixed with touchscreen interactive devices. After all, there was the Game Changer and Wowee’s AppGear, both of which had prominent appearances at CES.

The ePawn Arena is expected to be available in the “second half of the year”. I do’t seem to have a price, but the flyer I have on the product promises “patented technology provides state of the art performances at an affordable price”. Hopefully the average household can afford something such as this.

For this reason, I carry around a stylus, but Kindle Fire cover doesn’t have a convenient pocket for it. I also have to constantly keep track of the stylus along with my mobile device.

The txtRng is designed to alleviate these problems. Not only will the txtRng fit on your thumb or index finger so you can keep your touchscreen free from smudging, it is a lot harder to lose a ring.

In other words, the txtRng is “one ring to rule them all”. Yes, all Lord of the Rings references aside, the txtRng truly shows a near-marital commitment to a touchscreen mobile device. However, it is a commitment that I think we already have, honestly.

So will the txtRng be the wave of the future? Who knows. You never know when something like this will really take off, but considering that everything is going touchscreen these days, there is certainly room for the txtRng to make it big. If you want to get in on this, it costs about $29.99 for preorder here.

Why would anyone want this? Have you ever done something on your smartphone that is so much easier to do on a laptop or tablet? I don’t even like sending text messages because I can’t stand touchscreen keyboards. Fortunately, the LightPad has a keyboard attachment.

There is a video after the jump if you want to see how it works, and the display that you see here is a projector with a 854 x 480 resolution for an 11-inch screen.

Future models of this will have the same size display but with 1280 x 720 resolution. I’m not certain if the present model will have this feature, but the projector can be turned around to create a 60 inch display on the wall.

I am surprised that the LightPad is one of the first products of its type, as HDMI cable seems to be only good for playing videos and viewing photos from a smartphone. I want to see my entire smartphone screen on my HDTV, not certain apps.

This LightPad will make an appearance at CES in January, and, assuming I have time and can conveniently pass their booth, I will be glad to try it out.

Despite the fact it is getting some negative criticism, the Amazon Kindle Fire is finding its place in the tech community. It stands to reason that there would be protectors for them. BodyGuardz is now offering its protection for the Amazon Kindle Fire in several ways.

It has two kinds a scratch-proof screen protectors to provide protection from outside elements. As with most clear skin protectors of this type, it is custom-made for Amazon’s low-key iPad competitor. The ScreenGuardz not only provide protection, but stop glare as well. The Clear Skins also provide protection but are “optically clear to preserve its beauty and design”.

In addition to this type of screen protection, the company also has a Carbon Fiber Armor. This is made from strong PVC based film, and it is both “stylish and smooth to the touch”. The Armor reminds me of the Carbon Back Skin by id America that we reviewed before.

The Screenguardz are available on the Bodyguardz website for $15.95. The Clear Skin Screen Protectors are also available on the Bodyguardz website for about $29.95. The Armor Carbon Fiber for the Kindle Fire is available here for pre-order for the same price in three different colors of Black, White, and Red.

This 3D Hologram TPU is not that, but it does turn your smartphone into something cooler. This is a screen protector that creates a cool holographic effect when the smartphone is in sleep mode. As you can see, you can choose from a variety of interesting holograms.

As you can also see, it is possible to see the hologram while the phone is in use, but just barely. I wish I could have a chance to try this out for myself and report back to you. Perhaps they will be on display at CES in January. If so, I definitely want to at least get a picture, but I don’t think that will do it justice.

Considering that most smartphone users use a screen protector anyway, I don’t see why we can’t use one that is a hologram. I don’t know if they have any other designs than these, as I’m not certain whether consumers will want monsters and aliens as their hologram of choice.

If you want to see a better view of these products, head on over to the Audiotronic web site.
