There have been numerous attempts at designing partially transparent gadgets over the years, with the LG GD900 cell phone being a notable example. Fully translucent mobile devices are difficult to produce, however, as they would require a fully see-through battery, which hasn't been available yet. Stanford University researchers now claim to have developed such a device - a see-through, flexible, lithium-ion battery, suitable for powering mobile gadgets like cell phones, tablets or e-readers.  Read More

The New Trent iCruiser IMP1000 external battery pack is claimed to have enough capacity to...

Smartphones, tablets and media players have helped to make our mobile existence so much more tolerable - but they all suffer from varying degrees of the same problem. Battery life is always a nagging concern for regular travelers, leading many to carry some form of external portable power source like the Juice Pack Powerstation we reviewed recently. Even though Mophie's external battery pack proved its worth in our tests, we may just have to trade it in for the New Trent iCruiser IMP1000 - which offers over three times the battery capacity in a similar-sized format and claims compatibility with almost every device in the market.  Read More

Everlasting batteries and self-powering portable electronics have come one step closer to reality, according to the results of a new research by Australian scientists from Royal Melbourne Institute of Technology (RMIT). The group of researchers successfully measured piezoelectric thin film’s capability to turn mechanical pressure into electricity. It may sound like an idea from the realm of science fiction, but the discovery could eventually lead to laptops powered through typing.  Read More

With consumers used to the convenience of refueling their vehicle at the gas station in a few minutes, one of the biggest disadvantages of electric vehicles is the time it takes to recharge their batteries. Now, by separating the energy storage and energy discharging functions of the battery into separate physical structures, researchers at MIT have achieved a breakthrough that could allow EVs to be recharged in the same time it takes to refuel a conventional car. The technology could also provide an inexpensive alternative for energy storage for intermittent, renewable energy sources such as wind and solar.  Read More

Mophie's Juice Pack Powerstation charger for the iPhone, iPod, iPad and all devices that c...

For the rest of 2011, I'm visiting a new country every week or two. I'm not the biggest fan of getting lost, asking for directions, or getting ripped off by taxi drivers, so keeping my iPhone's battery charged is high on my list of priorities. I came across Mophie's Juice Pack Powerstation while I was doing my pre-travel gadget shopping, and was surprised at how small, light and cheap the unit was. So how does it stack up?  Read More

The mixing entropy battery could be used to build power plants at estuaries where fresh wa...

Scientists at Stanford have developed a battery that uses nanotechnology to create electricity from the difference in salt content between fresh water and sea water. The researchers hope to use the technology to create power plants where fresh-water rivers flow into the ocean. The new "mixing entropy" battery alternately immerses its electrodes in river water and sea water to produce the electrical power.  Read More

A new discovery by U-M researchers could see energy from the sun harnessed without solar c...

It has long been thought that, even though light has electric and magnetic components, the effects of the magnetic field are so weak that they could effectively be ignored. Now researchers at the University of Michigan (U-M) have discovered that under the right conditions, a light field can generate magnetic effects that are 100 million times stronger than previously expected. The researchers say the discovery paves the way for the creation of an "optical battery" that could harness power from the sun without the use of solar cells.  Read More

While those of us living in First World countries may take an easily-accessible source of continuously-flowing electricity for granted, such is not the case in developing nations. Many communities have little or no electrical infrastructure, and experience frequent power outages. While people wishing to read a book in the evening could perhaps use a simple lighting device like the Solar Pebble, the matter becomes quite a bit more serious should the lights go out at a hospital, in the middle of an operation. Many hospitals have turned to using kerosene lanterns, but Australian industrial designer Michael O'Brien has created what he believes is a better alternative – a low-cost battery-powered LED surgical lamp.  Read More

GoPro has just released its Battery BacPac, which allows a second lithium-ion battery to b...

Just last month, GoPro introduced the long-awaited LCD screen module for its viewfinder-less HERO HD actioncam. At the time, the company stated that the module was the first in a series of BacPac accessories, designed to extend the capabilities of the 1080p high-def camera. Now, the next of those accessories has been released, in the form of the Battery BacPac. It allows an included 1100mAh lithium-ion battery to be mounted onto the back of the camera (which already has its own identical battery), potentially doubling its run time.  Read More

The Icon charging unit for iPhone

We've covered a number of iPhone portable chargers in the past, ranging from the well-known Mophie Juice Pack to the environmentally friendly iCharge Dx. There are countless solutions that will ensure that your green battery indicator icon stays fully green, the difference with this iPhone charger is that it's been designed to resemble that very same indicator graphic. Appropriately, it's called the Icon.  Read More
