    I don't have experience of using them but I know they're out there. You will need to know how much current you need at 12V.

    I think there is only a couple of points to address.

    One what is the Current Requirements that you need for your system to work?
    How much you want to spend?

    There are many many systems out there. Some are Smaller then one would expect when you see pictures of them they look rather large. Then when you get them you find they are very small lol. j

    Here is a Buck/Boost converter that will give you around 90% Efficiency going from 5 volts to 12. However it only give 200ma of current. I think that will be only drawback on trying to do a Boost
