Road Chef 12 Volt Oven Big Bertha Dual Element 13L 20 Amp

The Big Bertha Road Chef 12v Oven is taking things to another level.

As the name indicated the Big Bertha is BIG, on the inside at least! It has a huge 13l cooking volume, so it is almost twice the volume of the Road Chef’s 6.6l. As you can imagine we needed more heat to fill this area, so we ramped the element up to 10A and put not one but TWO in it. One in the traditional place at the bottom of the oven, and the second one on the TOP, providing a more consistent even cook throughout the oven. Not satisfied with just having two elements we made it adjustable through a third knob, so you can choose BOTH elements, just the TOP, or just the BOTTOM according to what you are cooking or your power requirements. When running BOTH it has a 20A draw so there is no cigarette lighter plug provided (just Anderson plug) with Big Bertha and a minimum 6mm2 wiring is required, jumping up to 8mm2 for distances greater than 2m return.

Bertha is larger than the Road Chef, but not significantly so and weighs only 8kgs. We beefed up the mounting brackets making them longer, with three securing hooks and two attachment holes, so no matter how rough it gets you can have confidence in it. Due to the extra heat, we improved the door insulation keeping it cool on the outside. She comes with the two standard telescopic baking racks, but we have also included a custom designed stainless steel baking tray that hangs on the top rail. The tray is designed with air circulation in mind that creates a quicker, more even cook.
