Features of the AstroAI 4-Liter Mini Fridge

Cooling/Warming Function

Home appliance manufacturers have realized that many individuals prefer comfort and affordability.

No one would like to buy a separate mini-fridge and warmer when there’s an appliance that can do both.

The AstroAI 4-Liter Mini Fridge like many portable refrigerators has this dual feature.

What do we mean?

With this mini-fridge, you can have your cold beverages whenever you want some. And with just a touch of a button, you can also switch to keeping your food warm in it.

This is a great feature for people traveling or those who are usually occupied with work and will rather have their meals at a later time.

Temperature Control

As mentioned above, the AstroAI 4-Liter Mini Fridge has a dual temperature function. As a result, there has to be a way to change the temperature function whenever you want.

In this refrigerator, you can easily change the temperature with the switch located behind the refrigerator.

Before switching from cooling to warming function or vice versa, it helps to ensure that all items have been removed from the refrigerator and that the unit is unplugged from the power source.

By the way, it takes approximately one hour for the internal temperature of your refrigerator to adjust after switching the function.

Power Option

Electrical and electronic appliances including refrigerators come with one or several power options. Some of these power sources include AC/DC adapters, batteries, USB adapter, and solar panels.

The AstroAI 4-Liter Mini Fridge has both the AC and DC adapters.

With the AC adapter, you can connect your refrigerator to a 120V AC outlet in your home, office, or anywhere you have an AC socket.

The DC adapter, on the other hand, allows you to make use of this refrigerator in a vehicle. All you need to do is to connect it to your cigarette lighter and your fridge will be ready to serve.

You should only plug your fridge in when the ignition is on, to avoid draining your car battery. With this feature, you can enjoy your snacks at warm temperatures and your drinks at cold temperatures whenever you are on a trip.

Design

The AstroAI 4-Liter Mini Fridge comes in a very attractive design and you can purchase it in one of three colors – black, white, or blue.

The exterior of the unit is sleek and looks great wherever you decide to place it.

More so, the refrigerator is small and fits underneath tables and shelves, on car seats, office tables, and in small corners of your room.

It has a flat-back design that saves space in your room or vehicle. Its adapters and temperature control switch are located at the back of the refrigerator and are easily accessible.

What’s more? This design is quite modern. The sliver door handle, for instance, makes it look exquisite and makes it easier to open.

Meanwhile, organizing and cleaning the interior of the unit is easier because of the single shelf that is located right in the middle of the unit. This shelf allows you to arrange your beverage cans properly.

Portability

Most mini-fridges are portable and you can carry them around easily. Although their size makes it easy to lift them by grabbing their sides, some of them come with added features that make transferring them from one place to another hassle-free.

The AstroAI 4-Liter Mini Fridge has a strong handle on top for this purpose.

You also don’t have to worry about the handle breaking off because it is strong enough to withstand the weight of the cooler even when it is fully loaded.

What Users Are Saying About The AstroAI 4-Liter Mini Fridge

The AstroAI 4-Liter Mini Fridge has generated a lot of reviews from over a hundred people who have used the products.

A larger percentage of these users loved their mini-fridges for the various features it has to offer.

One of the major features is its design.

The users have commended this mini-fridge because it sits well in very small places and also attracts so many people to the room because of its appearance. Although it looks very small on the outside, it can fit 6 beverage cans just as it claims.

Nonetheless, a good number of the users didn’t put more than 5 cans to avoid the difficulty in extracting these cans whenever they are needed.

The AstroAI 4-Liter Mini Fridge also keeps items cold.

In fact, the users stored not just food and drinks in it but medication too. Some of the users who were diabetic were able to store their insulin in it and had easy access to the medication on long road trips. As one user said, ‘the refrigerator has been able to keep vials of insulin cold for long periods’.

Thankfully, because the two power options function well, users were able to use the refrigerator in their bedrooms while some others had it in their cars.

The only major problem encountered by a few users is the temperature function. For instance, a user kept her skin products in her fridge. When she returned from her outing, they had gotten so warm as the fridge was heating them instead of cooling them.

Thanks to AstroAI’s great customer service, refrigerators with operation issues were replaced with functioning ones in a short time.

Generally, users love the AstroAI 4-Liter Mini Fridge.

Our Verdict

The AstroAI 4-Liter Mini Fridge works effectively in cooling and warming your items. It is not meant for people who need refrigerators to form ice blocks or keep items at near-freezing or freezing temperatures.

It is for keeping already cold items cool and already warm items warm by maintaining a hot or cold temperature.

AstroAI’s customer service is great. So if you encounter any problems with your refrigerator, you can easily contact them and they’ll respond in a very short time.

The refrigerator also comes with a 3-year warranty, which is a very long time compared to other mini-refrigerators of this size.

In conclusion, the AstroAI 4-Liter Mini Fridge is a good choice for people who need to store up to 6 soda cans or items of equivalent sizes.

Related FAQs — AstroAI 4-liter Mini Fridge – In-depth Review

What are the applications of an AstroAI 4-liter fridge?

  • For office desks. If you spend a lot of time working at a desk, you can store homemade healthy lunches, snacks, or drinks in this unit. Also, this unit is great for home offices so you do not have to take trips to the kitchen.
  • To store homegrown food. If you love eating homegrown food, and your refrigerator is probably full of a lot of other items, you can make room in this unit and store some homegrown produce in it.
  • To keep food allergens separate. Managing food allergies can be very difficult, especially with children. Therefore, to keep the allergens away from the refrigerator, you can do so with this unit and keep away from the reach of children.

What can I store in an AstroAI 4-liter mini-fridge?

An AstroAI 4-liter mini fridge is a very important and handy unit, especially for college students. An AstroAI 4-liter mini-fridge in a dorm room can make any student you feel at home. In the same vein, an AstroAI on a working desk can make whoever is working feel more at ease.

An AstroAI 4-liter mini fridge can store the following:

  1. Beverages.
  2. Snacks.
  3. Milk.
  4. Leftover food.
  5. Cheese.
  6. Skincare products.
  7. Fruits.
  8. Chocolates.
  9. Eggs.
  10. Nuts (they last longer when stored in a fridge).
  11. Water.

How much ventilation does an AstroAI 4-liter fridge need?

An AstroAI 4-liter mini-fridge needs a ventilation path of about 200cm2 to flow over the rear of the unit.

Without proper ventilation, heat can build up around the unit, causing a decrease in performance, and later failure.

This unit works by pumping heat from inside, to cooling elements at the back. The heat which pumps from inside must escape enabling the unit to work efficiently. The elements at the back of the unit make the air around it to be heated and when this hot air comes up, it is replaced with cooler air from below.

Is it safe to put an AstroAI 4-liter mini-fridge in a closet?

This mini fridge carries heat from its inside to its surrounding space. That heat needs to escape because the higher the ambient temperature, the faster the heat will go back into the fridge. If this happens, the fridge won’t work as well as you expect it to because the temperature difference between the radiator at the back and the surrounding air will reduce, thereby reducing the heat transfer.

So, it is not safe to put an AstroAI 4-liter mini-fridge in a closet unless you create ventilation holes in the closet to let warm air escape.

If you do not create ventilation holes, the unit might get so hot that it doesn’t work as efficiently as it’s supposed to be.

Is it safe to place an AstroAI 4-liter fridge on a carpet?

Generally, it is not safe to place an AstroAI on a carpet.

Placing it on a carpet will reduce the airflow to the condenser, which is usually found at the bottom of the fridge. Also, a carper retains heat, leading to the poor performance of the condenser.

However, if you ever find yourself in a situation where you have no choice but to place it on a carpet, take note of the following:

  • Put something under the unit. Placing it directly on the carpet can cause bad odor and mold when the unit gets wet.
  • Close the unit doors properly.
  • Watch out for your coils, especially if they are at the bottom of the unit.
  • Check it at regular intervals.

How can an AstroAI 4-liter mini fridge be maintained?

  • Make sure the unit is free of paper and other flammable items.
  • Leave enough room behind the unit to allow air circulate freely.
  • Do not block the interior or exterior ventilation openings of this unit.
  • Do not let the main cable get stuck under the unit when putting it in position.
  • Do not connect the unit to power until you’ve taken out all the packaging.
  • Do not place the unit close to cookers, radiators, or in direct sunlight. This can cause the unit to work harder than it’s supposed to just to maintain the internal normal temperature.
