Oh a chepo extension cord would work too.

I'd try to keep it as short as possible. You can lose power over distance. Cheap cord like this the distance is shorter than better cords before you hit an amount that matters. But 5% loss means 5% less power and that would drop your temps. A Y adapter that is only a foot or two would be best but if you are uneasy working with power you might not want to mess with it or find someone who will do it for you.
