Yes, indeed. You can't expect power tools to be the best in every way if you're not giving them enough juice. When connecting extension cords, make sure they are long enough. That way, your tool won’t get short-circuited due to overheating caused by overworking itself! Besides, it's not about how far you stretch the cord but rather what kind of gauge it is. 14 gauge will always be more powerful than 10 or 12 gauge extension cords!
