Get my favorite travel charger ever for $79

I first encountered the MyCharge Peak 6000 at this year's Consumer Electronics Show. Since then it has become my most prized travel accessory. I literally never leave home (for a trip) without it.

Why am I so enamored with something as basic as a mobile charger? Simple: the Peak 6000 does right what every other mobile charger does wrong.

For starters, it packs a 6,000mAh battery, which can recharge an average smartphone three to four times. Even better, you recharge the Peak's battery by plugging the entire unit right into an AC outlet. Its fold-up wall prongs … Read more

Sulfur-based tech the answer to burnable lithium-ion batteries?

We've all heard stories about exploding cell phone and laptop batteries. A person is just walking down the street with his phone in his pocket and next thing he know his pants are ablaze.

The specific culprit batteries that cause such fiery incidents are lithium-ion batteries, which are known to have issues with heat. So, why can't there be chargeable batteries that are immune to overheating? There may be.

The Department of Energy's Oak Ridge National Laboratory (ORNL) has been working on new technology that looks to replace lithium-ion batteries. The lab has designed and tested a … Read more

Let your shoes do the charging

After researching a device that draws energy from knee movement, some mechanical engineering students at Rice University decided to see if they could get the same result from another, less intrusive wearable item: a shoe.

With help from the Movement Analysis Laboratory at Shriners Hospital for Children in Houston, the resulting PediPower shoes harness energy from the force of the heel hitting the ground. The prototype -- while admittedly big, unattractive, and impractical to wear 100 percent of the time (think sleeping, showering, etc.) -- demonstrates that the simple act of walking may one day power a wide range of … Read more

Five savvy ways to maximize your Galaxy S4's battery life

With a bigger battery and more efficient processor than its predecessor, the Samsung Galaxy S4 promises to at least survive a typical day. But as Jessica Dolcourt mentions, its slightly larger screen and abundance of features demand that added capacity.

Though the S4 (and most other phones) will almost always need a nightly charge, you'll certainly encounter days when you'll do just a little extra streaming, forget your charger at home, or find yourself staring at 15 percent with a long night ahead.

To get the most out of your battery, follow these best practices.

1. Disable superfluous … Read more

Apple envisions curved batteries for mobile devices

Apple is eyeing different shapes for batteries to find more room for them in phones, tablets, and other mobile gadgets.

Published today by the U.S. Patent and Trademark Office, a patent application dubbed "Curved battery cells for portable electronic devices," describes exactly that. The shape of such a battery would be changed during the manufacturing process to form a curve in its design. That trick would be achieved by heating up a set of curved plates and applying pressure to the battery cell.

The goal would be to create a battery that can make better use of … Read more
