Picture this: You’re out on the open road, exploring breathtaking landscapes, but the sun is blazing, and your RV feels like a sauna. Your built-in RV air conditioner is your best friend, but what happens when you’re off-grid, far from shore power? That’s where a reliable portable generator for RV air conditioner comes into play – or perhaps a clever soft start kit!
Keeping cool while boondocking or enjoying a remote camping trip doesn’t have to be a dream. With the right equipment, you can power up your AC and enjoy all the comforts of home. We’ve put together a list of 5 fantastic products that offer different solutions to help you beat the heat, from dedicated generators to smart soft start kits and even compact portable AC units. Let’s dive in and find the perfect fit for your adventurous lifestyle!
What to Look For When Powering Your RV AC
Before we jump into the reviews, let’s quickly chat about what’s important. Your RV’s air conditioner typically draws a lot of power, especially during startup (known as “inrush current”). This is why a regular small generator might struggle. You’ll want to consider:
- Wattage: How many running watts and surge watts does your AC need? (Usually 1500-2500 running watts for a 13,500 BTU AC, with higher surge needs).
- Generator Type: Inverter generators are usually quieter, more fuel-efficient, and produce cleaner power, making them ideal for sensitive electronics and RVs.
- Soft Start Kits: These devices drastically reduce the initial power surge when your AC kicks on, allowing smaller generators to power larger AC units.
- Portability: You’re on the move, so size and weight matter!
- Noise Level: Nobody wants a roaring generator disturbing their peaceful campsite.

FAQ: Portable Generators and RV Air Conditioners
Q1: What size portable generator do I need for my RV air conditioner?
A1: The size depends on your AC’s BTU rating. A 13,500 BTU RV AC typically needs around 1500-2500 running watts and 3000-3500 surge watts. A 15,000 BTU AC will need closer to 2000-2800 running watts and 3500-4000+ surge watts. Always check your AC unit’s specific wattage requirements (often found on a sticker on the unit itself or in its manual) and choose a generator with sufficient running and surge wattage.
Q2: What is “inrush current” and why is it important for RV ACs and generators?
A2: Inrush current is the brief, high surge of electrical power an appliance draws when it first starts up, especially motors like those in air conditioners. This surge is much higher than the unit’s normal running wattage. If your generator or electrical system can’t handle this initial spike, it can overload, trip breakers, or even damage your equipment.
Q3: Can I run my RV AC on a portable generator without a soft start kit?
A3: Yes, you can, but your generator will need to be powerful enough to handle the AC’s high inrush current. For example, a 13,500 BTU AC might require a generator with at least 3500-4000 surge watts without a soft start. A soft start kit can significantly reduce this surge, allowing you to use a smaller, quieter, or more fuel-efficient portable generator for RV air conditioner needs.
Q4: Are inverter generators better for RVs than conventional generators?
A4: Generally, yes. Inverter generators produce “cleaner” power, which is safer for sensitive electronics common in RVs (laptops, TVs, microwaves). They are also typically much quieter, more fuel-efficient, and have a more stable power output compared to older, conventional generators, making them ideal for camping and recreational use.
Q5: How much wattage does a typical RV air conditioner use?
A5: A 13,500 BTU RV AC typically uses around 1200-1800 running watts and 2800-3500 surge watts. A 15,000 BTU RV AC will use slightly more, often in the range of 1500-2200 running watts and 3000-4000+ surge watts. These numbers can vary by manufacturer and specific model, so always verify your unit’s exact specifications.
Q6: What is a soft start kit and why would I need one for my RV AC?
A6: A soft start kit is a device that reduces the sudden electrical surge (inrush current) when your RV air conditioner starts. By “softening” the startup, it significantly lowers the power demand on your electrical system. You would need one if you want to:
* Run your RV AC with a smaller portable generator (e.g., 2000-2200 watt inverter generator).
* Avoid tripping circuit breakers at campgrounds with limited shore power.
* Extend the lifespan of your AC compressor and generator.
* Reduce startup noise and light flickering.
Q7: Can I use a regular extension cord with my portable generator for RV air conditioner?
A7: It’s generally not recommended to use standard household extension cords for high-draw appliances like RV ACs with a generator. You should use heavy-duty, outdoor-rated extension cords (usually 10 or 12 gauge) that are properly sized for the wattage and length required. Ideally, use an RV adapter plug and a dedicated RV power cord (30A or 50A, as appropriate) to connect your generator to your RV’s shore power inlet. Improper cords can overheat and pose a fire hazard.
Q8: How difficult is it to install a soft start kit on an RV air conditioner?
A8: Installation difficulty can vary. Some soft start kits, like the GlymXia reviewed above, are designed for plug-and-play simplicity and can be installed by most DIYers in under an hour with basic tools and following the provided instructions (often including video guides). Others, like the Micro-Air EasyStart, may require a bit more comfort with basic wiring. If you’re unsure, it’s always best to consult a professional RV technician.
