Query: Don't leave home without it

Great little travel sized outlet multiplier. Hotels rarely have enough free outlets for me to power up everything I have at one time. Now I just need to find one free outlet and then I can charge up to 4 devices... usually a laptop, mobile phone and a camera battery or two. Couple this with an international plug adapter and you're ready to go just about anywhere.It has also come in handy at the airport. Outlet being used? No problem, just ask the person if you can plug this in and you can share the outlet... make a new friend or two or three.
