Keeps drinks hot and charges your phone!
Holds the temperature extremely well by itself, but with the added heating puck, this mug is invaluable! The handle is top-notch, too—very ergonomic. Oh, and the included gold spoon and the wooden lid are a classy touch. The best part? The heating base also serves as a wireless charger. All around, this is the best little gift I've given myself in years.

Wow! Awesome Mug and Warmer Set
I am really wowed with this mug and warmer set! The quality is spectacular, much better than I was expecting. The mug is a pretty green color and is made of stainless steel, so it holds heat extremely well. I like the unique handle as well and the handle stays cool to the touch. The warmer is easy to operate and you can control the temperature to a few different settings. This works great in my office to keep my tea warm while I am working. The warmer is extra neat because it can also be used as a phone charger. Very unique concept! It functions as expected and far exceeded my expectations.

Functional, Well Made, Works As Expected
I didn't expect to love this mug as much as I do! The first thing that caught my attention was how cute it looks, especially in this pretty pink color. But after using it, I realized that it has a lot more to offer than just its appearance.
The mug feels very well made, and I really like how comfortable the handle is to hold. The outside has a slightly textured finish rather than being completely smooth, but I actually like that because it gives it a nice look and feels durable. Everything looks nicely finished and good quality.
I also love that it comes with a lid to help keep the drink warm, and the little golden spoon is such a cute bonus! It gives the whole set a more elegant and sophisticated touch. The whole set feels pretty lightweight as well, despite the quality material that was made.
I made myself some matcha tea with milk and used the heating base to keep it warm, and it worked wonderfully! My tea stayed warm for a long time, which was exactly what I wanted. The controls are very easy to use, and I like being able to enjoy my drink at my own pace without having to keep reheating it.
Now, something that I think is really cool is that the heating base also works as a wireless phone charger! I tested it, and sure enough, it works! You just turn on the base, place a phone that supports wireless charging on top, and it starts charging. I love this kind of technology, especially when one little gadget can serve two completely different purposes. You can use it to keep your drink warm or to charge your phone. How convenient is that?
One thing worth mentioning is that the heating base needs to stay plugged into an electrical outlet to work. It doesn't have a rechargeable battery that allows you to use it without being connected to power. That's not an issue for me, but I think it's something buyers should know.
The mug is also easy to clean, great size, and I really like the variety of pretty colors available. It looks beautiful sitting on my desk or kitchen counter without taking up too much space.
I also think this would make a wonderful gift. It's cute, practical, and a little different from an ordinary mug. Between the matching base, lid, golden spoon, and wireless charging feature, it feels like a very thoughtful gift for someone who enjoys coffee, tea, or even hot chocolate.
Overall, I'm really happy with this set! It looks beautiful, feels well made, keeps my drinks warm, and even charges my phone. What's not to love? I think it offers great value for the money, especially considering the quality and the extra functionality. I'm so glad I got it, and I definitely recommend it!

Great little multi-feature warming mug...
This warming mug has many features to like.
It looks small but it's the perfect size for me. I don't drink a lot of hot drinks but I do enjoy a cup of tea while working sometimes. I typically sip all day on one cup and having this mug works great.
It has multiple temperature settings and can keep a beverage anywhere from 95 to 167 degrees which is quite hot.
The warming plate only gets hot when the mug is sitting on it, which is great. So if you forget to put the mug back on the warming base you don't have to worry that the base may bee a fire or burn hazard. It also has an automatic shut off feature that shuts off the base after a period of time if the mug is not in place.
The mug itself is stainless steel which provides for easy cleaning. I would warn though, that the sides of the mug can get hot enough to burn your lips so be careful about drinking when the beverage is very hot or if the setting on the base is set very high. This is not a big deal, since you should always be cautious when drinking a hot beverage, it's just in this case, both the beverage AND the rim of the mug may be hot.
The base is not rechargeable so it does need to be plugged in to be used. I keep mine plugged in on my desk and just turn it on when bing used.
I did have to read the instructions to figure out how to turn it on and adjust the temperature. It's not intuitive. But once I understood how it worked it's easy to use and has functioned reliably.
The coolest feature about this mug is that the base doubles as a mag safe phone charger!
It says this in the instructions but I didn't really get it at first.
It's not a feature I really need or use but I thought it was a cool thing to have.
There is really not anything about this mug I don't like

Great mug!
I love this mug and warmer so much! You can accomplish so much with both of them together, or separately. Either way, you get so much for such an amazing price!
First of all, you will receive a warmer, a mug, and a cute little spoon. I decided to get the black mug, but there are different colors availableWhen you plug the warmer in, you get to choose the temperature in which you keep your liquids. You can turn the heat all the way up and actually make your beverage warmer if you prefer, or keep it very hot if you would like.
Something that I was not expecting, is that when you do not have the included mug on the warmer, it doubles as a wireless phone charger. Excuse me, what??? Yes. It actually works.
Everything has been so well thought out, and after using this for a couple of weeks, everything still works very well, and I haven’t noticed any shortcuts taken. I highly recommend this.

A Practical Coffee Mug and Warmer Combination
The Greatic Warmer and Mug Set caught my attention with its practical combination of a heating-control base and a 16-ounce stainless steel coffee mug. I like the idea of having a matching mug and warmer together rather than choosing the pieces separately.
The 16-ounce capacity is an appealing feature, and the heating-control base is what interests me most about the set. It’s easy to picture this setup on a desk or beside a favorite reading chair.
I haven’t tested this set, so I can’t comment on its heating performance, temperature consistency, ease of cleaning, or durability. Those would be the key details in determining whether it delivers a great everyday coffee experience.
★★★★★
Perfect for a cup of coffee
This heated coffee mug is great for a large cup of coffee that needs to stay warm. Perfect for cold days. Highly recommend

Great Coffee Mug Warmer
This Coffee Mug Warmer Set is a desk essential! The 16 oz stainless steel mug keeps my coffee perfectly warm for hours. The easy touch temperature control is so convenient to use. This has eliminated my microwave runs to heat up a cold cup. The handle design feels great, and the uncoated steel is easy to clean. Ideal for home or office, I highly recommend this warmer for uninterrupted drinks all day! I also love the color.

Every mom needs this 😍
My toxic trait is that I want hot coffee all morning long, but I also want to take long breaks between sips and expect my coffee to stay warm. I get busy running after the kids, and I just forget to drink it, so I kept on heating it up… but now, I literally just have to remember to sit it back on the warmer, which makes me so happy! I feel like someone should have gifted me one of these a long time ago. Now I know that the other moms in my life with little ones need this!
I drink French press coffee, so my second cup is always in need of a warmup after sitting in the carafe, but now I can just pour it back into my cup and warm it/ keep it warm that way.
The cup is sleek and looks well made/ expensive. I expect it to hold up, but I can’t speak to its longevity yet, only its function. All I know right now is that it’s upped my morning game in a meaningful way!
★★★★★
Mug that keeps the coffee hot
This heated mug does what a regular mug never does. Sixteen ounces, stainless, touch control, and the coffee is still hot when you finally get back to it.
The temperature control is simple. Set it, forget it, and you are not reheating the same cup in the microwave twice. The burgundy looks good on a desk, and the outside does not get hot enough to be a problem when you pick it up.
Home or office, it earns the plug. Coffee stays coffee instead of turning into a lukewarm regret.
★★★★★
A good heated mug
This heated mug is really beautiful, and it does a great job of keeping drinks warm. The capacity is perfect for one person. I mainly use it for tea, and it works really well.
★★★★★
Amazing product
I really like the GREATIC Heated Coffee Mug. The 16 oz size is perfect for my morning coffee, and the self-heating feature helps keep my drink warm much longer than a regular mug. It’s especially convenient when I get distracted while working and don’t have time to constantly reheat my coffee.
The mug has a sleek, modern design and feels well made. It’s easy to use and does a good job maintaining a comfortable drinking temperature. I also appreciate the size—it holds enough coffee without being overly bulky.
Overall, this is a great option for anyone who enjoys hot coffee throughout the day. It’s convenient, practical, and has quickly become one of my favorite desk accessories.

Heating much AND wireless phone charger
⭐⭐⭐⭐⭐ 10/10 Love this thing!
I honestly really like this mug! I’m one of those people who makes a cup of coffee and then completely forgets about it until it’s cold, so having a mug that keeps it hot has been a game changer for me. 😂
The part I didn’t even realize I would love as much as I do is that it also works as a wireless phone charger!
It’s super easy to use, looks nice, and actually does what I wanted it to do. I’ve been using it pretty much every morning and have no complaints.
10/10 would absolutely recommend, especially if you’re a coffee addict like me! ☕📱
