Travel Buddy: How to cook

Review on my 12 Volt oven called a Travel-Buddy. Manufactured here in Australia. Showing how I roast a 1.3 kg Beef Roast. The Travel Buddy consumes on average 10 amps per hour.
I use my deep cycle battery to power my LED lights, fridge and 12 volt oven when I'm away from home. Using my Safiery 250 W High voltage fold-able solar panel to keep my deep cycle battery charged.
