Don't have your 1250 watt device and the cooling unit plugged into the same circuit. The starting amp draw of the cooling unit will probably be too much for the circuit, and trip the breaker.The panel is on the other side of the wall (outside) so I would have to embed the wiring in the wall.
I'll call my landlord on Monday and ask if I could add a 20A outlet, with written approval and ensure it's done by a licensed electrician. -Thanks
Hopefully this works out and I could plug the 1250W and cooling unit to the 20A outlet, then the rest of the lighter devices on the existing 15A outlets.
