I need to add a 12v socket and USB to my wife's 2007 Camry's trunk and my 2007 Volvo XC90 cabin; since I purchased NiLight's products before, and was happy, I decided to purchase this from them. NiLight didn't disappoint, good quality products, easy install, and the size is perfect for remote tucked-away install; you can install it flush or make a separate box for it. Definitely, going to buy again, maybe the one with rocker switches & volt reader for my power box. If you want to add-on USB & 12v socket to your car or for your DIY power box, get this!
