Innergie PocketCell (phone battery pack)
With more power accessories, high-end smartphone users will know full and well that modern day devices, despite their glitz and feature-set, may not last the full day. This pocket-sized power accessory will keep your smartphone powered up all day, with fast charging capability and a "magic cable" for the three most common devices out on the market, including micro-USB, mini-USB, and the 30-pin iPhone connector.
Kensington KeyFolio Pro 2 (tablet keyboard accessory)
As many travelers are swapping their bulky, heavy laptops for tablets, one of the main disadvantages is access to a keyboard. Kensington's KeyFolio is a universal removable keyboard for the most common 10-inch devices, and compatible with most Android devices. Powered by Bluetooth, it includes a stand to secure your tablet at the perfect angle.
Brookstone HDMI pocket-sized projector (pocket projector)
This pocket projector is perfect for presentation on the fly. It cranks out 1080p high-definition video up to 60-inches diagonally, and connects all HDMI-based devices. It can run for up to two hours on a single charge, and includes dual built-in speakers. All this, and it fits in the palm of your hand, or even in your pocket. (And, if you want to crank it out to play games from your smartphone in your hotel room, we won't tell anyone.)
