It is generally safe to use your PowerXL Air Fryer Pro on a granite countertop, but you should take precautions. Granite is heat-resistant, but the prolonged heat from the appliance can potentially cause damage.
You should always use a heat-resistant trivet or hot pad underneath the appliance for protection. This provides an extra buffer against direct heat transfer.
Always operate the appliance on a flat, stable surface. Do not use it on an unstable surface like a wobbly table.
Never place the appliance base on or near a hot gas or electric burner, or in a heated oven, as this will damage it and your countertop.
