Features of the Dometic Tropicool 33-Liter 12V Cooler/Warmer

Cooling and Heating Function

As with most appliances from this brand, this Dometic portable cooler has quite a number of hi-tech features which are uncommon with other products within this same price range.

For instance, it has a seven stage temperature regulation for both cooling and heating which helps the user to control how hot or how cool the unit gets.

This unit also features a memory function that will retain the temperature you set on the cooler. What that means is that even if you have to turn off the cooler for whatever reason, your settings will still be unaltered.

What’s more? The control buttons of this unit are dust and moisture-proof with an LED temperature display that is also weatherproof.

Energy Efficiency

This a feature we love and we are sure you will love too as it means you get to save your money by using less power. It has an energy class rating of A++ so you don’t have to worry so much about it draining your car’s battery or having a drastic effect on your power bill.

This model has an intelligent power saver circuit which functions in such a way that when the device has reached the set temperature range, it will automatically change to the energy save mode.

In this mode, the only energy consumed is what is required to reach the temperature in the box.


This Dometic cooler is compact and lightweight which makes it very portable and suitable for mobile use. It has a solid, fold-away handle that neatly folds down when it is not in use or needed.

For even more ease of use, the cooler can be powered by either an AC or DC power source. Simply put, this means you will be able to enjoy this cooler either from the comfort of your home or in any kind of vehicle.

It is also able to tilt to an angle of 30° which is great if you plan on taking it on a boat ride.


This 33-Liter portable cooler boasts a generous amount of space that can accommodate as many as 42 cans and even take some bottles standing in upright positions.

It also has a removable shelf which allows the user to customize the available storage capacity.

Cooling Efficiency and Noise Level

This high-quality thermoelectric cooler has such an exceptional performance that is almost at par with compressor operated appliances. It is able to cool items to as low as 30 °C (86 °F) below ambient temperature and also to heat them up to 65 °C (149 °F).

It operates with a wear-free fan and circulates efficiently through the hot air vents.

As  expected with a  good thermoelectric cooler, this unit is quiet.

With the engine of your car on, it would definitely drown out whatever noise that may have been previously audible.

You can also run the cooler in your bedroom or hotel room at night and still enjoy a good night’s rest without being disturbed by a noisy refrigerator in the background.

Smaller Capacity

Dometic 9-Liter Portable 12V Fridge/Freezer 

The Dometic Tropicool Cooler is a nice 12V cooler. But it may get a little heavy when it is full. So it may be better suited for larger families.

Against this backdrop, we suggest a much smaller, and lighter cooler to meet the needs of those who aren’t particularly pleased with the large size of the Tropicool cooler.

This smaller model from the same brand has all the quality that Dometic coolers are known for. It is however a little different in that it functions as a portable refrigerator or freezer. In fact, it is able to cool down to as low as 0°F.

However, unlike the featured product, it doesn’t have a heating function.

It has an adjustable shoulder strap which makes it easy to carry it around. Sadly, this cooler can only be used with DC supply. What this means is that you can’t connect it to a power source in your home, office or any place other than your vehicle.

It is also worthy of note that this cooler though smaller is much more expensive than the Dometic Tropicool cooler.

Larger Capacity 

Coleman PowerChill 38-Liter  12V Hot/Cold  Cooler

This versatile thermoelectric cooler from the renowned brand Coleman is pretty impressive as it keeps food items at an ideal temperature.

Due to its large capacity, this cooler is able to accommodate a considerable amount of food and drinks; making it perfect for families and on long trips.

Its design allows it to be placed horizontally and used as a chest or to stand vertically and be used as a fridge.

More so, the doors open from either the right or the left side which give more flexibility in its placement.

What Users are Saying About the Dometic Tropicool 35 Quart 12V Cooler/Warmer

A good number of those who bought this product were quite happy with its overall performance.

One thing that they love about it is that it is energy-efficient and has a power-saving function. They also love that it saves money and is environment friendly.

Another feature that they consider pretty cool is the indicator light which tells the user when the cooler is on so that they don’t have to open it frequently to check.

There is also a general consensus that this unit is quiet even when it’s running and once it switches to power saver mode, one may forget that there’s a refrigerator running in the background.

Of course, there’s hardly one thing that is a hundred percent perfect. So, as amazing as this cooler is, it does have a couple of drawbacks.

The first drawback is that although it comes as a lightweight cooler, it gets really heavy when it is fully loaded.

So, except the user will be transporting it in a vehicle, carrying it or moving it will not be convenient.

Another complaint that users had was that its cooling is dependent on the ambient temperature (well as expected; being a thermoelectric cooler).

So,  if it gets really hot outside or one is traveling through the desert it would not cool as well as it would at lower ambient temperatures. In such situations, it would help to provide some sort of shade for the cooler and ensure that it is not in direct contact with the rays from the sun as a verified user suggested.

Also, while the users love the seven-stage temperature regulator, some opined that it would have been a lot better if there was a temperature display system for users to monitor the temperature inside the cooler.

Our Verdict

True to its claims, this Dometic cooler true is a good investment.

This is because it delivers well on most of its features and should serve you for many years. Thanks to it being durable and low maintenance.

This quality, high-tech cooler is a suitable addition to a smooth road trip.

It also helps that the brand has an excellent customer service and will be willing to help and support a user if problems arise with the product.

This unit is well insulated and is able to keep your food cool for hours even when it is not plugged in.

However, it works best if you pre-cool both the cooler and the food you would like to place in it.

Also, being a thermoelectric unit, this cooler is dependent on ambient temperature; which is the temperature of the environment. This is not so bad unless of course you are going through a desert or it is extremely hot outside.

That said, we love that this unit runs quietly. Now, this feature may seem basic but it is very important if you plan to use the cooler in your hotel room. Alternatively, if you plan to run it constantly in your home or office it won’t be a disturbance in any way.

In our opinion, a cooler like this that offers versatility, excellent performance and convenience is worth the money.
