Review on 🥤 YJHome Smart Cup Cooler Coffee Warmer Mug Desktop Mini Fridge Electric Travel Heating Cooling Cup Portable Beverage Drink Chiller US Plug For Office Desk Coffee Beer Milk Cola Water Wine Drink by Fred Meeks

This unit is designed to cool and heat beverages using a thermal pad on the underside of the machine. I've tested the heating function in general, but I'm sure it works better than the cooling function. The main limitation of this device is the height of the bottle it can hold. Its clearance is about 4 or 5 inches less than a 16.9 ounce bottle. I'll try refrigerating the bottle without the cap and see what happens. I think this will probably still work. That means you need shorter bottles to warm a baby bottle. One of the larger bottles does not fit. The next question to consider is how sensitive you are to noise. It's amazingly loud. If you're in an open booth at work, it's loud enough that you might get complaints. Even in the closed space of the cube, people can show up to find out what makes the noise. It's louder than any computer or refrigerator. This is a midrange whine. In any case, it is very noticeable. But this is white noise, so it will affect different people in different ways. I work from home so the noise doesn't bother me, but I turn it off when I need to concentrate. Since it's a constant whistle, my VOIP calls don't pick up the audio. It cools better when the supplied metal cup is filled directly with liquid. Even to chill a drink in a can, I add a meager quarter cup of water to the cup. This works by induction - the larger the surface, the faster it cools down. And it's on the bottom plate that all the cooling takes place - note that the jars have a small metal ring that actually creates the contents. Air is not a good transport medium, liquid is. Turning it on and off is easy: just press the main button. It clearly shows whether it is heating or cooling. It also has a setting where it only reads the temperature and doesn't actively cool or heat. The temperature is given in degrees Celsius and the instructions do not indicate how to convert to Fahrenheit. I usually just double what it says and add 30 to it. This will get you pretty close to what is shown in F. However, the reading is consistent with the content. Within minutes it drops to single digits and settles in the 5 or 6 region for a while. Rest assured, the content hasn't reached 42 degrees yet. Most likely this is exactly what the cooling metal is doing. Also, it has no setting for how hot or cold it runs at maximum cooling or heating. But don't worry - Max won't freeze your drink or boil your water. And the temperature in the room depends a lot on how cool it can cool. Outside in 100-degree summer weather, it's not as effective as inside an air-conditioned home. Another tip is to turn the jar over from time to time. Coolers that run fast spin the glass. It doesn't have that option, so you can still do it manually. Just don't shake anything carbonated. Oddly enough, the instructions say not to drink carbonated beverages. But in another sentence, it clearly refers to carbonated drinks. In any case, I have had no problems using this product with them. I recommend it with reservations. Unless you have a specific use case, this probably isn't the best machine for the job. But for cooling, you'll likely spend more on any other device.
