If you travel for business the two must have devices are a power inverter and the Traveler 3 USB surge protector from Tripp-Lite. Travel devices and accessories are typically designed by people/companies who do not understand what features are important to business travelers who spend significant time working in airports, planes, rental cars and hotels. Tripp-Lites Traveler 3 USB travel surge protector has useful design features that make it an effective travel tool that I have found to be indispensible.
The Traveler 3 is small, just 3.5 x 4.75, with a streamlined plastic design that reduces the weight to less than 8 ounces. It has an 18 inch power cord (not a fold out prong) with a right angle plug that provides a low profile and tight charging connection to limited access outlets. Outlet height is 18 from the floor so the heavy duty power cord allows the weight of the cables and devices to be on the floor, not on the plug, so it wont fall out of the wall. There are 120V outlets on both sides that accommodate oversized charging adaptors and the 3 surge protected outlets (total) will convince the person hogging the only outlet in the gate area to share it with you. There is an LED diagnostic light that conveniently confirms if there is power from the outlet so you dont waste time trying to use a dead outlet. When you are finished the 18 cord and right angle plug wraps around the sides and fits neatly into a concealed space.
There are flaws and areas for improvement on the Traveler 3. The Mini USB cable provided is outdated and so few devices use it that it is unnecessary. The USB charging ports output is rated at 1 amp but in reality it is too low (less than 500 mAh) to be recognized by most devices so nothing will charge on any of the replacements Tripp-Lite has sent me. The 3 prong plug needs an 2 prong adapter for international travel. Overall though the key design features of the Traveler 3 USB outweigh any deficiencies or flaws and make this a reliable and productive travel accessory for the professional business traveler.
