By connecting this between the 2-pin figure-8 plug of your laptop's AC adapter and the AC cable, you can add an AC outlet (3 outlets). It has a total of 3 outlets: one on the front and one on each side. It's small and portable, making it suitable for use on business trips or in conference rooms. The rating is 125V/7A, supporting a total of up to 700W. The cable length is approximately 0.1m. I purchased this but never had a chance to use it, so I am selling it. It is a beautiful item, only tested for functionality.
