I have a small, personal size grill. Do you have to use these with a chimney starter? Or can they be used alone with the charcoal?

Hello, these can be used without a chimney starter, but they are much more effective when used with a chimney starter. We do make a smaller version of our chimney stater that is perfect for portable models, and you can find it at the link below.
