Buying Guide: What to Consider When Choosing 12V Coolers
12v coolers are convenient for on-the-go refrigeration. But not all of them are created equal.
Whether you’re spending a weekend in the woods or hosting a barbecue during tailgating season, the right 12v cooler for you should be able to deliver a solid performance.
Let’s look at the key features of 12-volt coolers that you need to consider:
1: Insulation
The cooling system is the first thing you have to look into before purchasing a 12-volt cooler.
A quality 12v cooler should maintain a constant internal temperature.
The temperature shouldn’t drop too fast, even when the lid is open. You should get a few hours of cooling once your car cooler is disconnected from a power source.
Look for a 12-volt cooler with a tightly-sealed lid to ensure that it can withstand direct sun exposure.
2: Storage Capacity
Are you going to use a 12-volt cooler for yourself or for your family of four? Do you need one that can readily fit into your car trunk?
Buying a 12v cooler that is bigger than what you need means higher costs and less storage space.
On the other hand, you’ll have to shop for more supplies frequently with a smaller 12v cooler.
For truck drivers and outdoorsmen who are frequently on the road, a large-capacity 12-volt cooler is ideal.
If you’re a solo user, a 30-qt. 12v cooler size should be enough. A 12v cooler with a 45-qt. capacity is generally recommended for those who plan to store food for two people.
Dual-zone fridge/freezer coolers are best for large groups.
3: Energy Efficiency
Unlike standard coolers, a 12-volt cooler requires a power source to function.
As a result, the energy consumption of a unit is a significant concern.
The more energy efficient your appliance is, the longer time you can spend off the grid.
Battery and solar-powered coolers may have higher initial costs, but they can save you more money in the long term.
Many high-quality 12v coolers combine well-built insulation, specifications, and compressor controls to provide greater energy efficiency.
4: Portability
Generally, 12-volt coolers are designed to be transportable from place to place.
If you want a 12v cooler you can move from the back of your car to the campsite, you need to look at certain features.
Make sure it has a lightweight body with durable handles and optional towing wheels.
Alternatively, if you simply want to keep your 12v cooler in one place, a unit with a large internal space and great cooling capacity should work well.
5: Price
12-volt coolers come in a variety of price points: from top-of-the-line to budget buys.
Standard thermoelectric coolers come at less than $100. They have reliable cooling and warming functions that can work for casual weekend trips.
At $300 to $500, you can find high-end thermoelectric coolers and compressor coolers with freezer options.
Premium 12v coolers with quality components, large capacity, and state-of-the-art construction can get up to $1,000.
Top cooler brands like Dometic and Engel are known for their exceptional coolers, but their steep prices can make them rather exclusive.
Nowadays, there are affordable brands that incorporate quality compressors capable of going head-to-head, with many higher-end brands out there.
What Are the Benefits of 12V Coolers?
A 12-volt car cooler is a great alternative to many traditional coolers.
See what 12-volt coolers can bring to the table:
- Refrigeration: Allows you to keep beverages and food cold for a longer period
- Convenience: Keepsfresh food readily availableandeliminates the need for ice
- Cost-effective: You can save money with stored food instead of eating out at restaurants
- Longer recreational time: Lets you enjoy camping trips longer with a stockpile of food and drinks
- Shorter travel time: Bypasses the need to make pit stops to buy supplies
What Are the Different Types of 12V Coolers?
There are THREE MAIN TYPES of 12v coolers that are available today.
Let’s look at each type to get a better understanding of how they work:
1: Absorption Refrigerators
Most commonly found in recreational vehicles (RVs), absorption refrigerators have three power sources: 12V DC, 110V AC, and propane.
It has a high power draw that can easily drain battery power.
As a result, absorption refrigerators tend to be inefficient for prolonged outdoor use. Running them on 110v AC can deplete your inverter, while propane requires an additional fuel line.
Most absorption refrigerators rely on the outside environment to maintain temperature and can only cool up to 30 degrees below ambient temperature.
2: Compression Cooler
Compressor fridges are the most common form of 12v coolers. It is designed much like home refrigerators.
These coolers are built for efficiency and durability.
The cooling system of a compression cooler depends on a cooling agent that manages the temperature.
High-quality compressors that require little energy can function as freezers, refrigerators, or both!
These coolers can work effectively even at an incline, compared to other coolers that need to be level when running.
The drawback of this type is that they are comparatively more EXPENSIVE than other options. They also need an auxiliary battery and other charging sources (e.g., solar panels).
3: Thermoelectric Cooler
Thermoelectric coolers can draw power from a 12-volt power source but cannot keep frozen food.
A 12v thermoelectric cooler can only cool 40 degrees Fahrenheit or below the ambient temperature.
It can work well in colder climates but is generally inefficient if the outside temperature is above 77 degrees.
Thermoelectric coolers also require more power than compressor fridges.
If you simply want to keep food and drinks cold during short trips, thermoelectric models are well suited for the job.
Otherwise, a compressor fridge or traditional cooler may be better options.
Frequently Asked Questions
Here are some related questions about 12-volt coolers that may interest you.
How Much Power Does a 12V Cooler Use?
The specific power usage of a 12v cooler depends on many factors, such as:
- Size
- Insulation
- Compressor configuration
- Chosen cooling temperature
- Ambient air temperature
Generally, 12-volt coolers consume 45 to 60 watts to maintain a consistent refrigerated temperature.
TAKE NOTE: The watts are only consumed periodically. Your car battery won’t drain immediately when a 12v cooler is actively being used.
Can You Use Ice in a 12V Cooler?
No, you should NOT put ice in a 12-volt cooler.
A 12v cooler can work just fine without ice. However, if the cooler can be configured to freezing temperatures, you can place a bag of ice.
Many 12v coolers can generate temperatures capable of freezing the entire interior compartment.
Can a 12V Cooler Drain the Car Battery?
12-volt coolers DON’T have the capacity to deplete your car battery when the ignition is on.
That said, some models can draw on the power source even when your car is turned off. Running a cooler overnight can also cause significant battery drainage.
Read the machine’s manual thoroughly before keeping it plugged into your car’s battery.
If battery drainage is a concern, look for a 12v cooler with a three-level monitor that allows you to adjust the battery voltage.
