When it comes to powering a rooftop AC unit, there are a few options. Some people choose to use RV park pedestal power or a generator. Others opt for solar generators, which can provide reliable and powerful charging solutions for RV ACs of different sizes. These generators can be stored in the RV or camper, ensuring a cool space even when away from power outlets.

The power requirements for a rooftop AC unit will depend on its size and brand. A 13,500 BTU air conditioner typically requires around 1000 to 1300 watts. To run this size of AC unit, you would need a generator with at least 3000 watts of power.

It's important to consider the start-up power requirements, as some AC units may have a much higher surge when they turn on. Additionally, the climate, home size, and efficiency rating of the AC unit will impact its energy usage.

Overall, rooftop AC units can be a great option for those looking for a more efficient and less obtrusive cooling system, but it's essential to weigh the pros and cons before making a decision.

Portable ACs:

Portable ACs are a great way to cool specific areas of your home or RV. They are also useful if you want to cut down on energy costs by not cooling rooms that are not in use. However, they can be expensive to run, depending on the size of the unit, the number of hours it is run, and the price of electricity.

The power consumption of a portable AC depends on its cooling capacity and brand. A medium-sized portable AC unit typically uses around 2900 watts per hour, while a larger one can exceed 4100 watts per hour. A 10,000 BTU unit, for example, can draw between 600 and 1000 watts per hour, while a 15,000 BTU unit can use up to 1700 watts per hour.

When it comes to running costs, a portable AC can cost approximately 17 cents per hour, based on an average electricity rate of 14 cents per kilowatt-hour and an average consumption of 1.2 kilowatt-hours per hour. So, if you run your portable AC for about six hours a day, you can expect a total energy consumption of 7.2 kilowatt-hours per day, which translates to around $30 per month.

It's important to note that these are just estimates, and the actual cost of running your portable AC will depend on various factors, including the efficiency of the unit and the rates charged by your electricity company.
