As the 12-volt RV air conditioning technology continues to advance, a wide range of innovative models are hitting the market, offering more options for campers and RV owners. When it comes to choosing the perfect air conditioner for your vehicle, there are a few important factors to consider. In this article, we will explore the best 12-volt battery-powered air conditioners for van life, taking into account different needs and requirements.
The Difference Between 12 Volt and 120 Volt Air Conditioners
Before diving into the specific models, it's important to understand the difference between 12-volt and 120-volt air conditioners. The typical 120-volt RV rooftop air conditioner is powered either by the RV park's shore power connection or the inverter connected to your RV's house batteries. However, powering the unit from a 12-volt DC power source, such as a battery bank or a generator, results in more efficient energy use. This makes 12-volt air conditioners ideal for smaller trailers and campers.
How Does a 12 Volt RV Air Conditioner Work?
12-volt RV air conditioners, also known as "Swamp Coolers," are evaporative coolers. They function by blowing hot, dry air through a moistened cooling pad. The pad absorbs the heat, causing the water to evaporate and cool down the RV. However, it's important to note that since it operates on evaporation, you will need to occasionally refill the reservoir to keep it functioning properly.
The Pros and Cons of Traditional 120 Volt Air Conditioners
When deciding between a traditional 120-volt AC-powered air conditioner and a 12-volt DC portable air conditioner, there are pros and cons to consider.
Pros of a 120 Volt Air Conditioner:
- High cooling capacity
- Widely available and easily replaceable
Cons of a 120 Volt Air Conditioner:
- Less energy-efficient
- Requires an inverter for off-grid use
The Pros and Cons of a 12 Volt Battery Powered Air Conditioner
Similarly, there are pros and cons when considering a 12-volt battery-powered air conditioner.
Pros of a 12 Volt Air Conditioner:
- Energy-efficient
- Quieter operation
- No need for an inverter for off-grid use
Cons of a 12 Volt Air Conditioner:
- Limited power supply
- Potential drain on house batteries
Running a 12 Volt Air Conditioner on a Generator vs. Battery Power
For those who enjoy boondocking off the grid, using a generator to power the air conditioner seems like a logical solution. However, there are drawbacks to this approach. Generators can be noisy, and the need for an inverter decreases efficiency and adds to the cost. Moreover, if anything happens to the inverter, the generator won't be able to power the air conditioner.
On the other hand, running a 12-volt air conditioner off battery power offers several benefits. It is much quieter than a generator and doesn't require an inverter. This results in better efficiency, as no energy is lost during the conversion process. However, it's crucial to consider the limited power supply and avoid draining lead-acid batteries below 50%. Lithium-ion batteries are recommended for running a 12-volt DC air conditioner.
