Peripherals maker Satechi has introduced the Portable Energy Station, a 10,000 mAh battery that'll solve some of your power woes on the go. The 1 Amp USB port will recharge nearly all of your smartphones and PMPs, while a second 2 Amp port will maintain pace with your iPad or other hefty tablet. Despite that capacious battery, it's a slender 7.4 ounces and should tuck neatly into your bag -- once you've picked it up for $50, that is.
