Camping, tailgating, or just enjoying some off-grid peace shouldn’t mean sacrificing comfort, especially when the mercury rises. If you’ve got a 13500 BTU air conditioner keeping you cool, you’ll know that finding the best generator for 13500 BTU air conditioner can be a bit of a puzzle. It’s not just about raw power; it’s about efficiency, noise, reliability, and how well your AC unit plays with different power sources.

FAQ: Powering Your 13500 BTU Air Conditioner
Q1: What size generator do I need for a 13500 BTU RV air conditioner?
A: A 13500 BTU air conditioner typically requires around 1,200 to 1,700 running watts and can have a starting wattage (surge) of 2,500 to 3,500 watts or even higher. Without a soft start kit, you’d generally need a generator that provides at least 3,000-3,500 starting watts to handle the initial surge, which usually translates to a generator with a running watt capacity of 2,500-3,000 watts. However, with a soft start kit, many 2,000-2,200 watt inverter generators can successfully start and run a 13500 BTU AC.
Q2: What is a soft start kit and why do I need one for my RV AC?
A: A soft start kit is an electronic device that significantly reduces the initial power surge (starting watts) required by your RV air conditioner’s compressor when it kicks on. AC compressors draw a large spike of electricity during startup. A soft start kit manages this power delivery smoothly, spreading the load over a few seconds instead of an instant jolt. This allows you to run your 13500 BTU AC on a much smaller generator (like a 2200-watt inverter generator) or even on a standard 15-amp household circuit, greatly improving versatility and fuel efficiency.
Q3: Can I run other appliances with my AC on a generator?
A: It depends on the size of your generator and whether you’re using a soft start kit. If your generator’s running watts are just enough for your 13500 BTU AC, you might not have much headroom for other power-hungry appliances like a microwave or coffee maker. A soft start kit frees up a significant amount of starting wattage, giving you more available power from your generator for other devices once the AC is running. Always check the total wattage of all appliances you intend to run simultaneously and ensure your generator’s running watt capacity can handle it.
Q4: What’s the difference between ducted and non-ducted RV ACs?
A:
* Ducted ACs distribute cool air through a system of vents and ducts built into the RV’s ceiling. This provides more even cooling throughout the entire RV and often results in quieter operation within the living space because the fan unit is typically in the roof.
* Non-Ducted ACs blow air directly from the unit mounted on the ceiling into the main living area. They are generally simpler to install and maintain but might not cool as evenly as ducted systems, and the noise from the fan can be more noticeable.
Q5: Are RV AC units difficult to install myself?
A: Installing an RV AC unit generally involves working on your RV’s roof, dealing with electrical connections (both AC and sometimes DC), and ensuring a watertight seal. While many units are designed for straightforward DIY installation, some manufacturers recommend professional help. If you’re comfortable with basic electrical wiring, sealing, and working at heights, it’s often doable. However, if you’re unsure, professional installation is always the safest bet to ensure proper function and prevent leaks.
Q6: What does ‘low amp draw’ mean for generators?
A: ‘Low amp draw’ refers to an appliance that consumes less electrical current (amperage) to operate. For a 13500 BTU AC, a low amp draw unit is highly beneficial when running on a generator because it means:
* Less strain on the generator: It won’t have to work as hard, potentially extending its lifespan.
* Better fuel efficiency: Less power consumed means less fuel burned by the generator.
* More available power: A lower amp draw for the AC leaves more capacity for other appliances on the same generator.
* Reduced risk of tripping breakers: Less chance of overloading your generator or shore power connection.
Q7: What’s the difference between running watts and starting watts for a generator?
A:
* Running Watts (or Rated Watts): This is the continuous power a generator can produce to keep appliances running steadily. It’s the maximum power the generator can output constantly.
* Starting Watts (or Surge Watts): This is the extra burst of power a generator can produce for a few seconds to start motor-driven appliances like air conditioners, refrigerators, or power tools. These appliances require significantly more power to “kick on” their motor than they do to simply run. Generators must be rated to handle this higher surge capacity to avoid stalling or tripping breakers.
Conclusion
Finding the best generator for 13500 BTU air conditioner doesn’t have to be a daunting task. As you can see, the solution isn’t always about buying the biggest, most powerful generator. Sometimes, it’s about choosing an energy-efficient AC unit designed for lower amp draw, or, more often, integrating smart soft start technology to make your existing or desired smaller generator work wonders.
Whether you opt for a feature-packed RV air conditioner from Fogatti or RecPro, or supercharge your current AC with a SoftStartRV, Micro-Air, or Spartan Power kit, you’re investing in comfort, convenience, and more efficient power management. These products offer fantastic ways to stay cool, extend your boondocking adventures, and make the most of your portable power setup. Happy travels, and stay cool out there!
