Extension Cords: The operating amperage for this unit is 12 Amps, but during start-up this unit will most likely draw more power. Also, extension cords will heat up when large power loads are used over time. I would use an extension cord rated for 15 Amps at whatever length cord you are using. Keep in mind the size (gauge) of the wire in the extension cord will increase over longer lengths to address voltage drop. Make sure you use the extension cords that have the correct Wire Gauge thickness for the length of cord you are using. If you are using a 100' cord make sure it's rated for 15 Amps and is made of 12-gauge wire. If you are using a cord 75' or shorter, make sure it's rated for 15 Amps and is made of 14-gauge wire. Generator Selection: First off, the relationship between watts, Amps & Volts is: Watts=Amps x Volts. Also, Amps=[Watts/Volts]. Generator size is based on operating/steady load watts. For example, a 2400W generator is rated at a max steady OPERATING load of 2400 Watts. When choosing a generator, make sure the generator can handle the actual START-UP load of the equipment you intend to run on it. For EXAMPLE, a refrigerator may have an OPERATING load of 2400 Watts (=20 Amps), but it may have a START-UP load draw of 2880 Watts (=24 Amps) needed to first start it up when you turn it on. In this case, you would need to get a 3000W generator to safely run this example refrigerator. Also, I would also strongly recommend using an INVERTER generator for any equipment with solid-state electronics (i.e., computer boards) in them. The built-in inverter technology regulates the power output of the generator so there are no under-or-over power surges coming out of the generator that can fry your electronics. In other words, if you plug this portable AC unit into a regular generator there is a good chance you will fry the AC's electronic circuit boards. In the case of this Frigidaire Portable AC rated at 12 Amps (=1440 Watts) (operating), as a MINIMUM, you can use a 2000W INVERTER generator that can handle the start-up load (up to 16 amps). I would recommend using a larger 2400W (=20 Amp) INVERTER generator so you don't overwork the generator. Hope this helps.
Sorry, there was a problem. Please try again later.We plugged ours into a grounded power strip extension cord and it runs perfect!
