I have mixed thoughts on this charger. It works well and chargers with speed. I love that it provides two additional outlets in addition to the two USB outlets. This realistically allows for an outstanding number of charging uses. However, all these options come at the cost of space. This charger takes up a great deal of space and depending on the location of the vehicles 12 voltage charger, it simply may not fit. The addition of the voltage meter is a nice touch, although I am jot sure I find it all that useful. If you have the space and you need to have several charging options, this is a great choice.
