I have one of these and I LOVE IT, especially for travel. Not only does it take ONE wall outlet, and adds an extra to it. There’s also the addition of the USB out… AND it holds a charge for later UNPLUGGED usage.
I’d highly recommend picking this up from A4C. It’s called the Belkin Travel Rockstar USB & Dual Outlet Wall Charger w/ Internal 3000mAh Battery Pack.
It’s already discounted to $34.95, however use the code SLICK50 and you get the thing for $17.47, which INCLUDES shipping. At that point you’re receiving $43 off of the list price and that beats everything out there!
