Use Your Favorite USB Keyboard On Your Phone With This Backup Battery

    It can be hard to choose a backup battery when the market is as flooded as Bluetooth speakers and iPhone cases have become. Manufacturers are now finding ways to include added value with their emergency power supplies, like Cerevo's new EneBrick that can turn your favorite USB keyboard into a wireless Bluetooth accessory for your tablet or smartphone.

    In addition to a decent 6,000 mAh power supply—enough to top off your smartphone a couple of times—the EneBrick includes an extra USB port letting you attach a tethered keyboard of your choosing. The $136 external battery (available sometime this month) then connects to your mobile device over Bluetooth, converting and passing along every keystroke.

    It seems like the perfect solution for road warriors whose phones or tablets won't last a full day, and who refuse to switch to a cramped mobile keyboard. [Cerevo via Tech-On!]
