Shocking: How Much Power Does a Camping Fridge Use?

How Much Power Does a Camping Fridge Use?

As a father of three kids and an experienced camper, I know the importance of having a reliable camping fridge. It not only keeps our food and drinks fresh during our outdoor adventures but also ensures that we have enough supplies to last throughout our trip. One common question that pops up when it comes to camping fridges is how much power they use. In this blog post, I will delve into this topic and provide you with all the information you need to know about the power consumption of camping fridges.

Understanding Power Consumption

Before we dive into the specifics of how much power camping fridges use, it’s important to have a basic understanding of power consumption. The power consumption of any electrical appliance is measured in watts. A watt is the unit of power that tells us how much energy an appliance uses per unit of time. In the case of camping fridges, their power consumption is usually measured in watts per hour (Wh) or amp-hours (Ah).

When you’re camping, you may not have access to a constant supply of electricity. Therefore, it’s crucial to know how much power your camping fridge will consume, especially if you plan to use it with a portable power source like a battery or a solar panel.


Factors Affecting Power Consumption

The power consumption of a camping fridge can vary depending on several factors. Understanding these factors will help you make an informed decision when choosing a camping fridge and planning your power source.

1. Fridge Size: The size of the camping fridge plays a significant role in its power consumption. Generally, larger fridges tend to consume more power than smaller ones.

2. Temperature Settings: The temperature you set on your camping fridge can also affect its power consumption. The lower the temperature, the more energy it will consume.

3. Insulation Quality: A well-insulated camping fridge will require less power to maintain a stable temperature. Look for fridges with thick insulation walls and quality seals.

4. Ambient Temperature: If you’re camping in hot conditions, your camping fridge will have to work harder to cool down its contents, leading to increased power consumption.

Calculating Power Consumption

Calculating the power consumption of a camping fridge involves a simple equation:

Power Consumption (Wh) = Operating Voltage (V) x Current (A) x Time (h)

To determine the approximate power consumption, you need to know the operating voltage and current draw of your camping fridge. This information is typically provided in the fridge’s user manual or on the manufacturer’s website. Multiply the operating voltage by the current draw and the number of hours you plan to use the fridge to calculate the power consumption in watt-hours.

For example, if a camping fridge has an operating voltage of 12V and draws an average current of 2A, and you plan to use it for 24 hours, the calculation would be:

Power Consumption = 12V x 2A x 24h = 576 Wh

It’s important to note that this is just an estimated calculation, and actual power consumption may vary depending on the factors mentioned earlier.

Tips to Reduce Power Consumption

While understanding the power consumption of your camping fridge is crucial, it’s also important to know how to minimize power usage to prolong your power source’s lifespan and prolong your time in the great outdoors. Here are some tips to reduce power consumption:

  • Keep your camping fridge well-insulated by avoiding direct sunlight and ensuring the seals are intact.
  • Pre-cool your fridge before adding food items to avoid unnecessary energy consumption.
  • Limit the number of times you open the fridge to retain cold air.
  • Consider using a separate cooler for drinks or items that don’t need to be kept as cold.
  • Utilize ice packs or frozen water bottles to keep your food cold without relying solely on the fridge’s compressor.


Knowing the power consumption of your camping fridge is essential for a successful and hassle-free outdoor adventure. By considering factors like fridge size, temperature settings, insulation quality, and ambient temperature, you can estimate the power consumption of your camping fridge and plan your power source accordingly. Remember to follow the tips provided to minimize power usage and maximize your time in nature.
