Need a longer cord

I recently went out and bought a portable air conditioning system.

It works really great and it is ultra powerful.

But the one issue I have with it is that cord is too short for where I want to plug it in and move it to. I need to go out and buy a longer cord that fits this portable air conditioning system. Otherwise the portable air conditioning system will be stuck sitting in a corner against the wall not cooling the room to the best that it can. My electrical outlets in this house are not exactly placed at the most convenient spots when it comes to wanting to run portable heating and air conditioning equipment. I would want my new portable air conditioning system further down the base of the wall in the rooms that I place it in. And it seems the only way to do this is to find a longer cord that will work with the portable air conditioning system. I will have a deep look online at various retailers and see if any have the exact type of cord I need. If they do not I will have to most likely go to some kind of electrical wholesaler or dealership to find the specific cord that I need to make my portable air conditioning system reach where I need to reach in the rooms that I keep it in within my home. I should be able to get an extension cord for my portable air conditioning system for not too much money. Or at least that would be the nice and ideal way for it to all work out.
