Michael Phelps isn't like most people, so it stands to reasons his pajamas aren't like most people's. There are no fuzzy bunny slippers and sheep-print flannel pjs for Phelps. He wears a high-tech compression suit from Under Armour.

The Recharge Energy Suit is a full-body suit designed to help the body recover from fatigue after training.

Under Armour claims the super tight compression fit pushes out the water damaged muscle fibers take on when sore, leading to a faster recovery. This is also probably as close as you'll get to knowing what it feels like to be swallowed by a snake.… Read more

One possible solution to resurrect a dead phone resides in Sony's latest portable CycleEnergy USB charger with a built-in hand crank, due in Japan on June 20 for 8,000 yen ($100).

The modular charger (CP-A2LAKS) features a dual port unit capable of charging two USB-equipped devices and a built-in 4,000mAh battery chargeable via AC power.

A Sony press release states the large battery capacity within can deliver enough power to charge a smartphone about two times, with an additional reference noting it would take about two hours to give the Xperia Acro HD smartphone a full charge. … Read more

Apple says its latest iPad model has been designed to keep charging, even after its indicator says it's reached 100 percent.

Following questions about the accuracy of the new iPad's battery status indicator and its recharging technology, Apple now says that it's part of its software to continue charging and discharging the battery when it nears 100 percent, and that there's no harm in leaving it plugged in.

"That circuitry is designed so you can keep your device plugged in as long as you would like," Apple VP Michael Tchao told AllThingsD today. "… Read more

The best way to review products meant to be used out in the trenches is to hit the trenches with those products in tow, going head-to-head in practical (preferably emergency) situations. In this case, we're talking iPhone cases that recharge your smartphone while protecting it.

Our two combatants in this intensely unscientific test are the Scosche Switchback Surge G4 backup battery case with kickstand for iPhone 4 and the PowerSkin recharging soft case.

The battleground was the parade for Chevrolet's 100th anniversary, part of the 2011 Woodward Avenue Dream Cruise car weekend in Detroit. With more than 1 million car lovers flocking to Motor City to view more than 40,000 custom cars, opportunities to take photos and videos were more prevalent than Chevy Small Block V8 engines. To the non-gearheads, there were a lot.

For two straight days, morning until night, I cruised Woodward in a 2011 Camaro as elite and custom cars came and went. Taking all of those photos and HD videos drains an iPhone's battery fast. So, I went into that crazy traffic jam with both the Scosche Switchback Surge G4 and the PowerSkin charged and ready. I tested how much protection they provided, how long they lasted, and how well they recharged an iPhone in constant use. … Read more

My time with the Accessory Power GoCharge Power Pack has been a bit of a roller coaster ride. When the device landed on my desk, I dismissed it as a basic 12-volt to USB adapter. However, closer inspection revealed some very interesting secondary features that are worth highlighting. Unfortunately, once I started looking closely, I discovered a few build quality issues that quickly quenched my excitement.

In the box, you'll find the GoCharge unit itself, an AC to USB power adapter, a Mini-USB cable, and a Micro-USB cable.

The GoCharge has about the same footprint as a business card (… Read more

The clean-energy geeks (definitely a term of endearment) at Stanford University have come up with a way to turn every river in the world into a power plant--no big ugly hydropower dams required.

Put simply, Yi Cui, associate professor of materials science and engineering at Stanford, and his research team want to put a newly developed rechargeable battery at the mouths of rivers; the batteries would take advantage of the difference in salinity between salt water and freshwater to produce electricity and charge themselves.

That's the simple explanation. For the explanation that includes a discussion of the relationship between voltage and the concentration of sodium and chlorine ions, check out the news from Stanford. That said, the basic concept behind the battery itself isn't too complex and is similar to other batteries--basically two electrodes immersed in water--but the Stanford team took advantage of nanotechnology, which is cool because...here, let's just let them explain it:… Read more

Energizer's AP1201 has been shipping for about a month, but one just showed up in the mail, so we thought we should give it a little ink because it's pretty nice.

The first thing to note about it is that it's relatively lightweight and thin but packs in a rechargeable battery and seems to offer good protection. We also liked the feel of the case, which is made partly out of hard plastic and partly out of recycled silicon rubber. While Energizer serves up a bunch of statistics on how much extra battery life it gives you (… Read more
