May 13, 2020

You want to be comfortable when you are in your home on wheels. One sure-fire factor that affects your level of comfort is the temperature in your motorhome. Almost all RVs have AC pre-installed, but not all do.

If you don’t have an ultra-modern motorhome you will have to opt for a portable AC for a car that suits your vehicle. You also have to consider purchasing one if you are buying a secondhand RV that doesn’t have an AC unit or that has an irreparably broken one.

Here we will give you a list of the best options to choose from when you’re looking to purchase a portable AC unit. Let’s kick things off by showing you the different types of portable coolers out there.

Suitable Portable Coolers for Your RV or Camper Van

There are a number of different types of portable coolers, but not all of them are practical for use in your RV or camper van. You will find that handheld options, for example, will only be good for cooling one person and may only work for cooling a person’s face. To help you sort through the many options on the market, here are the most suitable for cooling down your camper van or RV.

Portable AC

Portable AC for RV or Van

A portable AC for a van is self-contained and is an ideal choice for use in RVs or caravans in climates with higher humidity levels. They are good for cooling small spaces and typically have wheels so they can be moved around easily if necessary. They are designed to sit on the floor and come with a setup kit so they can be easily and quickly put together.

Pros

  • Effective: These types of coolers are some of the most effective on the market thanks to how well they cool a space.
  • Different size options: They can be found in different sizes to accommodate different size rooms as well.
  • Dries out the air: If you are in weather that has more humidity you might want a cooler that will dry out the air. This will help you stay cool as well as comfortable on the road.

Cons

  • Uses a chemical refrigerant: You will have to spend more time and finances on maintenance.
  • Doesn’t work well for a dry climate: AC contributes to dehydration and aggravation of respiratory problems.
  • Most models are bulky and heavy: This makes it hard to move them around, from vehicle to vehicle or room to room.
  • High energy consumption: This makes these units more expensive to run for longer periods of time.

Portable Electric Fan

Electric fan for RV and Van

Portable electric fans are a good option for RVs since they can be easily moved from one place to another. There are different types and sizes available. You can find window box fans, regular box fans, clip-on fans, desk or table fans, dual window fans, pedestal or floor fans, and hassock fans.

Pros

  • Lightweight: Designed to be very lightweight, these types of cooling units are easy to lift and move around from place to place and vehicle to vehicle.
  • There are cheaper models: You will find that these come at very affordable prices when compared to other types of coolers.
  • Low energy consumption: These are great for on the road, as they don’t use a lot of energy. So you can be cool while conserving energy, and your trips can be longer and more exciting.

Cons

  • Ineffective: don't actually cool the air, just move it
  • Doesn’t work well for a dry climate: dry out your skin since they blow air on your body

Evaporative Coolers

Evaporative cooler for RV

This is a type that cools the air by evaporating water. It provides a solution for the downsides of AC units and portable fans. The machines work by pulling in stale air and moving it over a cooling pad or rigid cooling media. Cool water evaporates and as a result, decreases the temperature of the air.

There are multiple factors that affect just how much this type of cooler will be able to cool the air. The cooling power of evaporative coolers is higher when you have higher temperatures and lower humidity.

Pros

  • Energy-efficient: Unlike your vehicle’s AC unit, they can be very efficient, as they use only a fraction of the energy required to power your vehicle's AC.
  • Effectively cools down the air: Unlike fans that just move the air around, an evaporative cooler effectively cools down the air.
  • Humidifies the air: Since it uses water to cool down the air, it also adds moisture, which is great for arid conditions.
  • Doesn’t use chemical refrigerants: This makes it safer and also lowers your maintenance costs.
  • Doesn’t require installation: You simply need a socket, a USB port, or a battery to work an evaporative cooler.
  • No need to run the car engine to use: Since they can run from a battery or power bank via a USB cable, there is no need to have your vehicle engine running to get this cooler to work.
  • No need to install and fit the side of a car: These are small, portable units that can be taken inside and placed on a desk or other surface.
  • Eco-friendly: By using these types of coolers you greatly reduce your carbon emissions, and also
  • There’s no heat exhausted as a result of the evaporation process.
  • It doesn’t use any Freon-like liquids.
  • It allows you to decrease the energy spent.

Cons

  • Doesn’t work for a very humid climate: Since these types of coolers use water, they will create more humidity.

Take These Factors into Consideration When Choosing a Portable RV Cooler

The type of portable AC for RVs you need depends on a number of factors. You have to take into consideration your climate conditions, including dryness and humidity. You need to consider just how much cooling you need. This also depends on the size of your van, as well as extreme weather averages. Will you be spending time in a cooler area, a parked spot with shade? Or will you be on the road, in the sun for hours? When you are out in the sun, you will, of course, need more cooling power.

Powering your AC unit with the use of your RV’s engine will not be very feasible when you are on the open road for multiple days. This is where a generator comes in. Your AC unit will work on power that is supplied through a 12V socket. There is also the option to run AC units on a gas generator, but this is a very costly option, and there will be a lot of refilling stops. You can even find solar items that can help you harness the power of the sun and reuse it to power your cooling unit.

If you are using a handheld cooler you will have options for battery-powered units, as well as will be able to power them with a USB cable.

The size of the cooler you choose should be dependent on the size of the space it needs to cool. If you don’t choose a cooler with an adequate capacity you will be wasting energy, and the temperature will still be uncomfortable for everyone.

Wrap Up

When you are on the road in your RV, camper van, or car, you want to ensure you keep yourself and all your passengers or guests comfortable. You can’t always rely on the cooling units the vehicle comes with. In these times you may benefit from having a portable AC for a car. There are a couple of units types to choose from, all with their own sets of advantages and disadvantages.

Qries

An optimal solution is an evaporative cooler as it provides a solution for the cons of the other types of coolers. Where AC units or fans are not energy-efficient or do not actually cool down the air respectively, an evaporative cooler does. And if you need a truly portative option that is quite affordable, very user-friendly, and highly effective, try Evapolar.
