Road Chef Big Bertha Oven

The Big Bertha 12 Volt Oven is the latest innovative product in the Road Chef range. It takes 12 volt cooking to the next level with 13 Litres of cooking capacity it is nearly twice that of the traditional Road Chef oven and it has two elements. This gives you the choice of cooking with just the TOP element, just the BOTTOM element or BOTH at the same time. It can be tailored to what you are cooking and what your power supply is. Using the top element is great for meals like nachos or bruschetta. For baking scones and biscuits where heat is best coming from the bottom then you can select the relevant setting. Then to turbo boost your 12-volt cooking select both to have them operate together which is ideal for larger meals especially roasts and other meats. Each element will independently draw 10 Amps / 120 Watts at 12 volts when operating fully. When both are used at the same time, they will draw 20 Amps/ 240 Watts at 12 volts. The ONLY power option that you must have to power the Big Bertha is via the supplied Anderson Plug. Other 12 Volt ovens, offer the options of a cigarette lighter or Merit Plug however, these cannot be used for Big Bertha as the wiring is not sufficient. Additional wiring is required, and our recommendation is a minimum of 6mm for a maximum route length of 2m. From 2m to 5m route length we would recommend 8mm2 or greater as if it is used while charging the voltage is higher than 12v.

To use Big Bertha, you need to set all three dials on the front of the oven. Firstly, select your element/s then rotate the temperature gauge to the required setting and finally turn the timer switch to the desired cooking time and the red LED light will illuminate. It takes about 20 -30 minutes to preheat to 160-180°C depending on your element selection and power supply. The oven is thermostat controlled so the elements will disengage and reengage to maintain the set temperature. A bell will ring to remind you that the oven has turned itself off when the time is up.

Big Bertha has two baking racks as well as a deep-dish baking tray (included in the box). They can be used interchangeably according to your cooking style with the racks being telescopic making it easier to remove the food. The baking tray is ideal for meals that are wet, like marinated chicken wings, or ones that release liquid like a pork roast. It can be placed on the bottom of the oven but is designed to hang on the top rail inside the oven allowing for maximum air flow, 360° around the meal being cooked. Reduced airflow allows cooler air to build up near the meal surfaces causing slower, uneven cooking. The ingenious design of the Baking Tray allows hot air to easily circulate around the product, picking up the heat faster & cooking more evenly. The oven is fully insulated so even while heating at 180°C the outside of the oven is safe to touch. Additional to the double layer of insulation on the door there is an internal sheet of silicone reducing its external temperature. The unit is safe to recess into a cupboard or shelving system as it does not require ventilation. If you want to mount your Big Bertha it comes with two extra strong mounting brackets making it easy to install either tied ‘down’ to a shelf or tied ‘up’ to the underside.

Made from stylish 304 stainless steel it is ready to handle even the harshest of situations and environments. It is easy to clean and comes with a 1-year warranty. Big Bertha is flexible enough to cook for one but big enough to easily cook for the whole family, or more!
