I added a LCD TV to my RV. I needed a 12 volt outlet for the TV. The Magnadyne adapteris perfect for my use. The USB charger ports are a bonus. I have already used them tocharge my Android and ipod.The mounting hardware plus the velcro tape made mounting the device under my video switchingunit a snap. I cut off the 12 volt plug that comes with the unit and hard wired it to my 12 voltsystem.
