Hey this might have gotten a post previously, but wanted to share this piece of good gear that I "field tested" during this cruise. Monster makes a 3 outlet (Outlet to Go) powerstrip that is made for travel. It also has a usb port for charging usb devices. It is very compact, light and easy to pack. Picked one up before our latest cruise and it woked very well. Was able to charge the kids cameras, my mp3 player and phone all at the same time. An added bonus is a blue LED that is embedded at the head of the plug. When it is plugged in, there's enough light to act as a small night light. I kept it plugged in during the cruise and it provided just enough light for the kids to see their way to the bathroom in the middle of the night. Definitely Top Gear!
