Yes, most electric grills for balconies can draw power from a standard household outlet if they’re the only appliance plugged in while in use. A few require hardwiring, so be sure to check the owner’s manual before operation and even purchase. If using a standard outlet, you should keep the lid closed as much as possible; exposed heating elements lose heat at a rapid pace that 110-volt supplies simply can’t keep up with. Grilling with the lid down is less of a concern when pulling from a 220-volt outlet that pumps out much more power, but we’d still recommend it.
