The perfect tea drinking temperature is between 60C and 65C. These thermos cups can help you maintain the temperature

Anyone who has unfortunately forgotten to drink a cup of freshly brewed tea and comes back to drink it when it is cold will know that temperature affects the taste of your favorite tea. You probably took a sip, made a face, and then turned on the kettle again for a fresh cup of coffee.

According to the Royal Society of Chemistry, this is because the perfect tea drinking temperature is between 60 and 65 degrees Celsius. Scientists suggest that this calorie is to "avoid vulgar sips caused by trying to drink tea at too high a temperature."

They also recommend sipping in a favorite place, “where quiet and calm will elevate the moment to a special dimension”, while reading George Orwell’s "Down and Out" in Paris and London. It is the material for dreaming.

However, if you are one of those who work long hours, especially during the pandemic and working from home, or chasing children around all day long, then you will most likely only drink tea at the right temperature. If this is the case, the cup warmer may become your best new friend, especially when you are too busy to observe your brew to make sure it does not pass the best position.

Insulation cups have heating coasters or cups with heating elements to maintain the perfect drinking temperature, and some will even notify you when the drink arrives. Some devices are plugged into the power source, while others can be placed on your desk and plugged into the computer while you are working because they are powered by USB. To help you decide which one is best for you, we have collected some of the most popular products on the market and introduced them.

We tried a series of different thermos cups, including heating coasters, self-heating thermos cups and smart devices controlled by apps. We also chose those that are powered in different ways, including through power plugs and USB, to see if this affects performance.

We looked at the quality, design, features, and functions of each device we tested, and compared them at price points. We also drank a lot of tea, coffee and hot chocolate, and tried to keep them warm or even heated-it turned out that you always need to use a flat-bottomed cup, so don't try to use a domed heater-bottom container.

We use the app for everything, so why not use your cup? With this smart device, you can fully control the temperature of the drink, and it will even notify you when it is suitable to sip through the app and the LED indicator of the cup itself. The app is simple to use and has many features, including allowing you to set your favorite temperature between 50C and 62.5C, personalize the color of the LED, track your caffeine consumption, and keep your mug software up to date . In addition, it is suitable for Apple and Android devices.

The black mug we reviewed has a capacity of 295 ml, but there is also a 414 ml large-capacity mug for people who like to drink large cups of hot drinks, and there is also a white mug. It has an excellent taste because it is very smooth and not too thick, thanks to the ceramic coating on its stainless steel core, it stays cool no matter how hot your drink is.

If you put the mug² on the charging coaster, it can keep your drink at the optimal temperature for several hours, but it can be taken out and taken anywhere in your home or office, providing 1.5 hours of battery life. It also knows when to automatically turn on when pouring hot liquid, and when to turn off. This smart mug is at the higher end of our price range, but it has many features, so you are definitely worth the money.

If you don’t want to worry about charging your device, this power-powered coaster mug is a good choice. The stylish black design uses a glass top, even a huge cup has enough space and a touch-activated light switch. The numbers (one to five) on the control panel show the temperature settings, allowing you to choose the temperature setting that suits you. The range is between 35C and 100C, but we will question why it needs to be so high, because no one will drink boiling tea or coffee. We are impressed by how fast this vacuum flask heats up. It uses a gravity sensor to shut itself off when removing the cup-but please keep it out of the reach of children as they may be on the electric stove Burn yourself.

The price of this gadget shows that under any budget, the vacuum flask will never be out of reach. It is perfect for those who are looking for a serious heating coaster that can reliably keep their drinks warm but not too hot. The design is simple and attractive, with convincing wood-effect trim around the silver metal bakeware. As promised, it maintains a constant temperature of 55 degrees Celsius and heats our cups evenly. It also has a non-slip base to ensure safety. We like the simplicity of plugging in when needed and removing when done-no need to fiddle with switches.

Let go to sleep, well, bears will lie, especially when they put that cup of tea on the bread you have forgotten to toast. This thermos cup certainly has an interesting factor, almost imitating the peeling carpet of mini taxidermy. It is made of silicone, sturdy and durable, suitable for daily use. The device is powered by USB, heats up quickly, and can maintain a temperature of up to 70C. We especially like that if there is any spillage, you can wipe it with a damp cloth or sponge to keep your cup warm, clean and fresh.

Take a look at this exquisite bone china cup and you will find that it is an attractive 325 ml cup. But hidden in it is smart technology, which means you no longer have to drink tea or coffee at any temperature other than your ideal temperature. Its core is the technology of waiting for your beverage to reach the scientifically proven perfect temperature of 60C to 65C-you will know when it gets there because the light bar in front of the cup will remain bright red-and then keep it in two and a half There is one hour in the hourly thermal cycle. When you finish your last sip, it will intelligently turn off the power.

This is a beautiful cup because of its good bone china structure, and it never feels too hot because the base stays cool even when heated. It comes with its own coaster, can be charged wirelessly, and surprisingly, the cups can also be washed in the dishwasher. This is the most expensive one we have tested, but if you refuse to drink any tea outside of China, it is worth buying.

If you can't bear to leave your feline friends when you go to the office, this cat cup warmer can at least maintain their similarity throughout your working day. It is made of silicone, feels high-quality, and has lovely details, including a pink heart-shaped nose and white beard. It will heat up quickly and reach a maximum of 65C when plugged in to maintain the ideal drinking temperature. Because it is USB powered, this charming thermos cup will be your perfect desk companion.

The gorgeous design and quality of this durable thermos goes against its reasonable price tag. It looks super stylish, with colorful metal insulation panels, a pillow-like frame made of matte silicone, and an LED screen on the front. The two buttons are hidden in the raised circular frame and displayed as arrows. The heat intensity of the hot plate can be increased and decreased with a simple push. The temperature range is from 55C to 75C in increments of 10C. This gadget can even heat beverages below the temperature of your choice-but we find that it takes a while to heat warm beverages, so we don’t recommend trying to heat cold beverages to 75C , Otherwise you will wait longer than you want. Samnate thermos mugs are available in green, light pink and cute pink designs with rabbit ears. It comes with an American plug, but a British power adapter is included in the box.

Music lovers and all retro things will flock to this cool (or we should say hot) thermos. This is a simple plug and play USB device, as long as it is powered on, it can keep the beverage warm at a high temperature of 70 degrees Celsius. The design is very interesting, it looks like a miniature vinyl, it is made entirely of silicone, so the sticker will not fall off over time. Just like the other all-silicone gadgets in our review, it can be wiped clean with a damp cloth or sponge when it is not plugged in.

For a personalized, fun and enjoyable drinking experience, we like Ember Mug². The functionality and advanced technology are second to none, and the cup itself has an excellent taste. Most importantly, it reliably keeps your tea or coffee at the best drinking temperature for you. We also like the appearance and function of the Samnate coffee cup heater, and we highly recommend Mustard's hot music vinyl record cup heater as a fun and economical choice.
