AS per the others the answer is YES easily, however wether you can drive without loosing the contents of the slow coocker is another question (and FAR harder to answer, especially if it's soup!).
The slow cooker is made by Road Pro..and it works just fine. I have bought an extension lead so that I can run it off the cig lighter, rather than the 12v circuit of the van itself. Although it appeared to me to work o.k. off the van's 12v system, I was strongly advised against it...particularly with the electronic control box on our Burstner being so tempremental.
But it is true...the smell of dinner cooking while you are travelling is a joy to the senses.
