Can I use it indoors?

Yes. It is sold for indoor and outdoor use and runs on a standard household outlet. Use it near ventilation, since electric grills still produce smoke and grease spatter.

How hot does the 1600W element get?

1600W is enough to grill burgers, chicken and vegetables, but it will not sear like a gas or charcoal grill. Expect more of a steady cook than a char.

How many people does the 20-inch surface serve?

The 20-inch cooking area handles roughly two to four servings at a time. Larger gatherings mean cooking in batches.

Does it need propane or charcoal?

No. It is fully electric and plugs into a wall outlet, so there is no fuel to buy or store.

The grill surface and drip tray come out for washing. Grease can collect around the tray, so clean it after each use rather than letting it build up.

How does it compare with a George Foreman or Weber electric grill?

It is a simpler, more basic unit. Name brands offer better temperature control, lids and nonstick surfaces; this one covers the basics at a lower build quality.
