I wanted something to add power outlets to my older honda odyssey, which originally had only one switched outlet in the front.  This offered everything I was looking for and more.  The fuse for this is in the main unit, not in the DC plug, so the plug can be cut off to allow hard wiring this unit to the vehicle.  Besides giving me 2 always on DC outlets, this also gave me 2 USB charging ports, eliminating the need for the dc to usb power adapter I had been using.  I couldn't be happier with it.
