Cooluli 4-Liter Mini Fridge [In-depth Review]

The Cooluli 4-Liter Mini Fridge is one of the products that Cooluli manufactures.

The brand, Cooluli, was established in 2016 in Brooklyn, New York, United States when a group of individuals who noticed a lack in the thermoelectric industry came together to develop products that would be beneficial to the entire populace.

The brand is also well-known for releasing portable cooling and warming systems to create a world where anyone can be anywhere and have their items at the exact temperatures they want it without having to go to great lengths to keep them that way.

So whether you are taking a trip or getting some work done in your garage, Cooluli says you can bank on the durability of any of its products that you decide to get for yourself.

Let’s get into more details about what this product has to offer.

Who Needs the Cooluli 4-Liter Mini Fridge

The Cooluli 4-Liter Mini Fridge can be used by anyone. This mini-fridge is almost always used as a beverage cooler and can take up to six cans weighing 12 ounces each. This could get very exciting because it can satisfy a moderate nuclear family.

The mini-fridge may also be useful for corporate workers because of its sleek and portable design. It can be placed on the working table and blend in with the environment, even adding an extra sense of style.

The AC, DC, and USB power adapters it possesses makes it easier for individuals to charge their mini-fridges. In this era of smartphones and power banks, having a USB adapter to a mini-fridge is a good thing.

For individuals who don’t like to have their lunch or breakfast early, the mini-fridge is also capable of keeping the food warm till you’re ready to eat. The beliefs that they all work to only cool beverages has been crushed by this function.

So, whether you would like to have your drink hot or cold, in the office, bedroom, or the nursery, the mini-fridge serves at the desired temperature.

Features of the Cooluli 4-Liter Mini Fridge

Warming Function

Although the concept of mini-fridges that can warm foods are not novel, this mini-fridge is one of the few that have that ability. Initially, people had to put food in the fridge only after 2 hours of leaving it outside so it doesn’t heat the inside of the fridge. But we have now learned that bacteria can grow on food when left outside for too long and kept at temperatures less than that which would kill these organisms.

Thankfully, the mini-fridge has lifted some burdens.

What do we mean?

You can now place your food while it is hot in your mini-fridge and keep it inside to avoid unwanted life forms. In addition to this, you also can keep the food at the required temperature by adjusting the fridge settings.

Cooling Function

This Cooluli 4-Liter Mini Fridge has a working cooling system that keeps your beverages cold. We suspect that it is the reason users mostly employ it as a beverage cooler.

This particular feature makes it suitable for family gatherings and small office meetings in areas where large refrigerators aren’t accessible.

The cooling system involves heat transfer from one side of the cooler to the other. Along with this heat, electrical energy is also transferred, creating a temperature balance in your mini-fridge.

The mini-fridge is considered environmentally friendly because the cooling system works effectively without refrigerants, thus making it safer than several others in this category.

Design

Every mini-fridge is characterized by its small size and its portability. The Cooluli 4-Liter Mini Fridge also has a very sleek and impressive design apart from the small size.

This design makes it stay somewhere and look great wherever it is placed. This is one of the reasons why it can be used comfortably in offices.

The matte finish on the outside is as good as you think it is. Cleaning a mini-fridge has never been easier, and this can be achieved by wiping over the interior and exterior. The built-in magnetic door and handle placed over the top makes carrying it from one place to another easier without having to worry about destroying the content of your mini-fridge.

Temperature Control

Due to the dual ability of the Cooluli 4-Liter Mini Fridge it is a necessity for the fridge to have a good temperature control system. Having a stable and standard way to control the internal temperature of the fridge makes it easier to monitor the items in them.

The mini-fridge has a switch which helps you adjust the internal temperature and change from cold to hot or vice versa. It also has an easy-to-read display screen, to know the current temperature of your mini-fridge and help you decide when to adjust the settings.

That said, it is essential that you wait for about 30 minutes before switching from one temperature to another, to allow for proper temperature regulation in your machine.

Power Options

Cooluli is indeed making research and developing products that are both environmentally friendly and satisfy the needs of the people.

What are we talking about?

The Cooluli 4-Liter Mini Fridge is built with an AC and DC power adapter. It also features a USB adapter which provides an easy and portable avenue for you to charge the unit. This simply means you won’t run out of options so easily whenever you need to get the unit up and running.

The AC and DC adapters make it very easy for you to switch from the normal indoor 110V (AC) to the DC power from your vehicle, using the cigarette adapter. This keeps your fridge in a regular temperature at all time and keeps your items in the best conditions till you’re finally ready to make use of them.

Here’s the caveat though: it is not advisable to use laptops and other computers that have USB charging ports to charge this unit because they do not generate enough power for the mini-fridge.

Adapter Option

Twowings 7-Can Portable Mini Fridge

The Twowings 7-Can Portable Mini Fridge which is also employed to cool or keep foods warm is a thermoelectric mini fridge that also works by transferring heat from one side of the fridge to another.

While the Cooluli Electric Mini Fridge has both AC/DC adapter and USB adapter, the Twowings Mini Fridge has a special 12V DC adapter.

What does this mean?

The Twowings Mini Fridge will be a good choice for vehicles that provide because of its 12-volt function. This is beneficial for some individuals because they only require the fridge to be used while they’re on a journey. They have larger refrigerators they use at home.

People that intend to use it at home shouldn’t be so worried, as they can purchase a 220V AC power cord to be used with the mini-fridge.

What Users Are Saying About the Cooluli 4-Liter Mini Fridge

There have been mixed reviews about the Cooluli 4-Liter mini fridge, although most of them are positive reviews by customers that have used the product for quite some time.

Most of the customers consider the Cooluli mini fridge as a great product because of the qualities it offers for a mini-fridge sold for less than $100. Most of them have made use of their appliance for over a year and have utilized it for various things which are majorly storing beauty products, canned beverages, and even breast milk and other baby solutions.

While this fridge keeps the items very cold when set to the cold option, there has been a general remark about the fridge which isn’t so good.

After a while of using it to cool their items, condensation began to pile up behind the fridge and at the bottom, which leads to leakage of water when the temperature gets warmer.

The buildup of ice on the back of the fridge affects the four screws which help keep things in place. After a while, the screws get rusted and the machine begins to malfunction.

Also, the mini-fridge fits its description perfectly of having to take six cans. Fitting lesser than six cans into the fridge have been preferred because of the difficulty encountered in removing the beverages when they are ready to be taken.

Nevertheless, the mini-fridge which is mostly used for cooling items has been praised by most people for its working efficiency.

Our Verdict

The Cooluli electric mini fridge for cooling and warming works efficiently to keep food items and other materials at the required temperatures. It freezes up in a short while, cooling items right in time for them to be used, and has proven to be very useful for individuals that need something portable.

The major problem we seem to be facing with this appliance is the condensation buildup.

Is this a big problem?

Yes, it is. What we’re trying to point out is that this build-up over time causes a breakdown of the machine, shortening its life span. Most users are yet to figure a way around it, but once their mini-fridge breaks down, they do request a new one from the manufacturers due to the warranty placed on the product.

Being a portable fridge, the capacity it carries is not expected to be large, but you should know that it is difficult keeping complete 6 cans in there as said in the description because of the problems of removing them when in need. The only way around this is if you place slim cans in the unit or decide to place less than 6 regular size cans.

Nevertheless, the Cooluli 4-Liter Mini Fridge has received a lot of positive feedback from users who have employed it to cool their beauty products, baby foods, and beverages.

Going past the minute problems, it is a great option for people looking for a mini-fridge that can sit anywhere and cool a few personal items.
