It's light. It's drop-dead easy to use. And it holds 18 hours of charging for devices like smartphones, MP3 players and tablets. Just connect it to the device via USB and push the button.

I can't believe more people don't travel with a power strip. I've had TSA agents and flight attendants remark on what a great idea it is, but to me it's a no-brainer. Hotels almost never have enough power outlets, especially near the desk where you're working and need access to all your recharging gadgets.
For Windows 7 users only, this free download turns your laptop into a WiFi hotspot. You're in a hotel charging exorbitant prices for WiFi, and you have to pay it for each of your WiFi-enabled devices. With Connectify, pay once for your laptop, then use your laptop to connect your phone and tablet for nothing. Brilliant, simple, and free. And it works flawlessly and is ridiculously easy to install and use.
