A:Answer This unit draws 90 watts, or 1.5 amps. If you use a GOOD 14 or 16 gauge SHORT (10 foot or less) extension cord you should be O.K.
Just remember this unit runs most of the time, and small cords like lamp extension cords WILL heat up!
A safer alternative might be to put nicely covered blocks (bricks?) to raise the unit up, this will also increase cooling!
Good Luck!
