Most Road Warriors travel with electronics that need power. I have tried many different travel surge protectors and have found the best: Belkin Mini Travel Surge Protector. This has two USB ports, 3 three-prong plugs and the best part is that there is a swivel three-prong plug. I can't tell you how many times I find that the most convenient plug to a bedside comes through a lamp in hotels. The problem is that the configuration of the plug varies and sometimes it is sideways, other times not. If you have a travel surge protector that does not have a swiveling plug, you are often not able to use it. Belkin's well-designed plug solves that problem.
