Guest Power is the world's smallest and simplest surface mountable, retractable power device available. Requiring only an 1-3/4" diameter hole, it is very compact and easy to install. To use it all you have to do is to pull the cap out and plug in your device, making it perfect for phone chargers, laptops, or any device that requires a charge or power. The cord is 7' long, providing ample length and flexibility to move the receptacle where it's needed. Easily integrate PCS56 into desks, counter tops, tables, conference rooms, kitchens, chairs, or any type of furniture where convenient power is needed. And plug the other end in to any outlet. The o-ring in the cap provides a water tight, spill proof seal, and securely holds the cap in place when not in use. Rated 13A/125VAC.
