Bigbruin.com tried the SnapPower Guidelight Outlet Coverplate
A quote from the article:
In this review we are going to cover an item from SnapPower, a company that's sole focus is to make your wall outlets more useful. Their main offerings are both 120V wall outlet cover plates, with one style that offers a USB port for charging your devices, and another style that offers a nightlight with a built-in sensor to automatically turn on when it gets dark. While they also offer USB cables that could be used with their "SnapPower Chargers", their wall plates are clearly the novel offering that makes them of interest.SnapPower Guidelight Outlet Coverplate @ Bigbruin.com
