EcoSol PowerTrip portable storage and battery backup device (price TBA)

The only thing worse than getting locked out of your car at work is getting locked out of your cell phone at work. And while no remote battery backup gadget is perfect, I like what Canadian-based Ecosol Solar Technologies is doing with its PowerTrip portable solar charger and data storage device. Due later this year, the unit can use wall power, USB power and the sun to bring your dead phone back to life. Plus it holds a couple of gigs of digital file storage. Tell me that is not handiest thing you can think of?

Sleek Audio: SA6 In Ear Earphones ($250)

Father-and-son audio maestros Mark and Jason Krywko adopt a take-no-prisoners attitude with in-ear earphones. The Palmetto, Fla.-based duo's SA6 earbuds not only can be customized to sit in your ear canal properly, but everything from the length of the earphone mount to the fullness of the electronics that sit on your ear can be adapted to fit your particulars. The effect is a more comfortable listening experience that blocks out traveling noise and still sounds great. Even better, the entire unit is built from tough aluminum and uses only the best cables and parts. Though not entirely indestructible, the SA6s are darn close. For keeping your money-making wits about you, the SA6s are the state of the art.
