The Rapid'BBQ is an electric resistance that heats up when the mains is connected. The heat effect is clearly enough to light the charcoal in the barbecue very fast and without failure. It takes 8-10 minutes depending on how the charcoal is positioned in contact with the Rapid'BBQ and the quality of the charcoal. This picture is taken after 8 minutes (the Rapid'BBQ is here placed a little outside the charcoal, just for illustration purposes). This is the moment to disconnect the mains, take the Rapid'BBQ out of the barbecue and put the grill back on.

Of course, the front part of the Rapid'BBQ is still very hot, and you should be careful with the burning hazard, even if it cools down quite quickly. Put it in a safe place on its stand so that nobody gets burned.
