S3 12oz Heated Coffee Mug with Temperature Control for Espresso | AI Beverage Detection, Auto Heating, Digital Display, Button/App Control. 120–150°F, 1°F Temperature Adjustment, 2–4H Runtime

My life runs on two things right now: coffee and a baby's unpredictable schedule. As a new mom on maternity leave, my coffee consumption has become less of a leisurely ritual and more of a critical fuel source. The problem was, my coffee was always going cold. I'd brew a cup, take one sip, and then my son would need a diaper change, or to be fed, or just to be rocked. An hour later, I'd be back in the kitchen, staring sadly at a full, cold mug of coffee. I'd microwave it, knowing I was ruining it, but desperate for that warm caffeine hit. I’d seen the commercials for the Ember coffee mug, but it seemed like an extravagant purchase. A friend, who is also a mom, told me her Ember Mug didn't last long enough for her chaotic days. She then pointed me to the VSITOO S3 Smart Mug, specifically highlighting its longer battery life and durable build. I took a chance, and it has been nothing short of a lifesaver. The first thing I appreciated was how straightforward it is. You don't need to be a tech wizard. The mug feels solid and well-made in your hands. I got the white one, and it has a clean, modern look that fits right in on my kitchen counter. The scratch-resistant coating is a must with my hands always full of baby lotion, wipes, and who knows what else. I've knocked it against the counter a few times, and it still looks new. The lid is my best friend—it clicks on so securely that I never worry about spills, even when I'm carrying it with one hand while holding my baby in the other. This heated coffee cup is clearly built for the real world, not just a pristine office desk. The AI Smart Heating is the star of the show for a parent. I pour my coffee, and I don't have to do another thing. The mug senses it and starts heating automatically. I usually just use the simple button on the mug itself to set it to 140°F—my perfect "can-sip-it-now-but-it's-still-warming" temperature. Then, I walk away. It doesn't matter if I'm gone for twenty minutes or two hours. When I finally get a moment to myself, I can pick up that self-heating coffee mug and take a glorious, warm sip of coffee. It’s a small thing, but that consistency, that one reliable pleasure in a day of chaos, is incredibly powerful. It feels like the mug is on my team, working in the background to preserve a little piece of normalcy for me. I have to compare it to my friend's experience with her Ember Mug 2. She constantly complains about the battery life, saying it dies just as she's getting settled. The VSITOO heated coffee mug rechargeable battery is a game-changer. I charge it overnight, and it lasts all day. I'm not exaggerating. I might have three or four separate cups of coffee or tea throughout the day, and the mug still has juice left by the evening. The boil-dry protection has also been a blessing. In my sleep-deprived state, I've left the mug on after finishing my drink. Knowing it will safely shut itself off instead of overheating is a huge weight off my mind. The IPX7 waterproof rating means I can wash it quickly and thoroughly without a second thought, which is essential for hygiene with a newborn in the house. This VSITOO S3 was worth every single penny. It’s not a luxury; in my current life, it’s a necessity. It has single-handedly solved one of the most frustrating daily problems of new motherhood. It’s durable, intelligent, and relentlessly reliable. If you are a parent, a caregiver, or anyone whose attention is constantly being pulled in a dozen directions, this temperature controlled mug is your answer. It’s a truly thoughtful product that understands real-world use, and I am so grateful for it.

My life is currently measured in two-hour increments: feed the baby, change the baby, try to sleep, repeat. In this whirlwind, hot tea is my anchor, my tiny piece of adult solace. But for months, actually finishing a cup of tea while it was still hot was a mythical concept, like a full night's sleep. I'd heat water, steep my tea, take one sip, and then... well, you can guess. The microwave became my nemesis, systematically destroying the delicate flavor of my chamomile or green tea until it tasted like boiled regret. A friend in my parenting group mentioned her Ember mug but lamented that it couldn't survive her chaotic schedule; the battery was always dying at the wrong time. She pointed me toward the VSITOO S3 Plus Smart Mug, highlighting its rugged build and longer battery. It sounded too good to be true, but I was desperate. I can now confidently say this self-heating mug hasn't just changed my tea routine; it has preserved my sanity. From the moment I held it, the VSITOO felt different. It has a sturdy, dependable weight to it. The 316 stainless steel construction doesn't feel delicate. I've accidentally bumped it against the sink, the counter, even dropped it (from a short height, don't judge!), and it doesn't have a single mark, thanks to that scratch-resistant coating. The lid is my hero. It clicks on so securely that I can carry it with one hand while rocking my daughter with the other, with zero fear of a scalding spill. This heated travel mug is designed for real life, not just for sitting on a stable desk. The IPX7 waterproof rating is another huge plus. When I do get a moment to wash it, I can just rinse it under the tap without a second thought, which is crucial for hygiene with a newborn in the house. The AI Smart Heating is the star of the show for a sleep-deprived parent. My brain is not operating at full capacity. The beauty of this smart coffee mug is that I don't need to think. I pour the hot water, drop in the tea bag, and the mug senses it and starts working. I use the button to set it to 130°F for my herbal tea—a temperature that allows me to sip it immediately without burning my tongue but keeps it warm for the long haul. Then, I can just walk away. It doesn't matter if the "walk away" lasts for twenty minutes or two hours. When I finally circle back, my tea is waiting for me, perfectly warm and flavorful. That first hot sip after a stressful moment is a powerful, calming ritual that this mug has made possible again. The coffee cup warmer function is so consistent and reliable. Comparing it to the stories I've heard about the Ember Mug 2, the VSITOO's battery life is its superpower. The heated coffee mug rechargeable unit lasts for hours. I charge it once in the morning, and it gets me through the entire day and into the late-night feeds. I don't have to constantly remember to place it on a special base. It's just... ready. The dry-boil protection has also activated multiple times when I've been pulled away and forgotten to turn it off. Knowing it will safely manage itself is one less thing for me to worry about. This temperature controlled mug isn't a frivolous gadget; in my current life, it's an essential tool for self-preservation. It delivers a small, hot cup of comfort exactly when I need it, and for that, it has earned a permanent spot in my daily routine and my highest recommendation.

I know this is half the price of the Ember mug, but ultimately you get what you pay for. There are several issues with this product. Number one, the app user experience is extremely poor. It constantly disconnects from your mug, which means you have to re-pair the mug with your app every single time. There’s no user manual in the app, so I don’t even know how to pair it sometimes; it’s hit or miss. I think you just press the button for two seconds or something, but the Bluetooth connection is very inconsistent. Number two, the battery lasts less than two hours at 145°F - more like 1.5 hours, so you’re only getting about 30 more minutes compared to the Ember mug. Additionally, the app doesn’t allow you to preset the temperature; every time you close the app, it defaults back to the manufacturer’s preset. The charger plate is quite big compared to the Ember mug too - kind of bulky. I will be returning this mug. I am very disappointed. Yes, it is half the price of the Ember mug, but I would gladly pay more for a more premium feel, a better app, and a more consistent user experience. I did reach out to their customer support multiple times - they've asked for my device and order info., then disappeared - and did not provide any assistance with the issues. The frustration with this mug and the app is not worth saving $50 over the Ember mug.

I travel constantly for work, so having my drinks stay hot is non-negotiable. I’ve tried so many heated mugs before, but the VSITOO S3 Plus has honestly been the BEST experience I’ve had — especially as someone who lives on coffee during flights, airports, and long overnights. The temperature control is amazing. It keeps my coffee at the exact heat I want (I personally love it on HOT), and it stays consistent the whole time. No more sipping lukewarm coffee halfway through boarding or during a long gate hold. It seriously makes such a difference when you’re always on the go. The battery + warmer combo is perfect. The mug alone keeps my drink warm for hours, but when I set it on the charging base, it becomes a full heater. I love that it’s auto-sensing — I don’t have to press anything, it just knows when the mug is on the base and adjusts the heat. The design is beautiful and durable. I’ve taken it in my tote bag, my work bag, my suitcase… and it still looks brand new. The matte black is super elegant, and it feels very high-quality in your hand. The stainless steel interior also means no weird smells and super easy cleaning. Perfect for flight attendants, travelers, or anyone with a busy schedule. I use it at home, in hotel rooms, at the airport, and during layovers. I even take it to the aircraft when I’m doing my preflight so my drink stays hot. If you’re a coffee or tea lover, you’ll love this. Overall: This mug has replaced all my other heated mugs. It’s reliable, strong, keeps the perfect temperature, and looks classy. If you’re someone who’s always running, flying, traveling, or just wants a hot drink without reheating 10 times — THIS is it. Worth every dollar.

DID NOT LIKE THIS CUP FEELS LIKE PLASTIC INSIDE .IT DOES KEEP LIQUID VERY HOT .I THINK IF IT HAD MORE SAFE PRODUCT INSIDE THEN ITS A NICE CUP IT DOES AS PROMISEDI GIVE 4 STAR FOR THAT

I'll be the first to admit it: I have a problem. I am a productivity and tech optimization nut. My entire home runs on a smart ecosystem, from the lights to the thermostat, all meticulously programmed for maximum efficiency and comfort. But for years, one daily irritation remained unsolved: the tragic lifecycle of my morning coffee. I'd brew a pour-over, savor the first perfect sip at 145°F, and then watch helplessly as it descended into lukewarm mediocrity. I was aware of the Ember Mug 2, but its reputation for limited battery life and delicate build kept me from pulling the trigger. It felt more like a novelty than a robust tool. When I dug deeper into the smart mug category, the VSITOO S3 Pro Smart Mug kept appearing, with specs that read like a tech spec sheet. I decided to put it to the test, and after two months of rigorous use, I'm ready to declare it one of my most impactful smart home additions. The unboxing felt appropriately premium. The mug itself, in the sleek "slate gray" I chose, is a minimalist's dream. It’s all clean lines and a matte, scratch-resistant coating that feels fantastic to hold. The build quality is immediately apparent. It has a confident weight, signaling the premium construction without being a burden. The 316 stainless steel interior isn't just for show; it gives the mug a feeling of indestructibility that a ceramic-coated competitor lacks. The lid is a engineering highlight—it doesn't just sit on top; it seals with a precise, magnetic click that screams quality. I've carried this heated travel mug from my home office to my backyard and back, and its leak-proof promise has held absolutely true. The "smart" part of this smart coffee mug is where the VSITOO truly shines for a user like me. The integration is seamless. Charging is via USB-C, and the pairing process with the app was instantaneous. But the real magic is the AI sensor. You pour in your coffee, and the mug just… wakes up. It’s a beautifully simple, zero-friction interaction. No button to press, no app to open. It intelligently recognizes the presence of a liquid and gets to work. I live by data, and the VSITOO app is a data-lover's dream. I can watch the real-time temperature graph, set my desired temp to the exact degree (I'm a 142°F guy for my light roast), and monitor battery percentage. The precise temperature control is astounding. I've tested it with a separate thermocouple, and it holds within a single degree of the set point. This isn't a coffee cup warmer; it's a precision laboratory instrument disguised as an elegant mug. Let's talk about the comparison. A colleague of mine has the Ember Temperature Control Smart Mug 2. The differences are stark. The most significant for my workflow is battery life. His Ember mug famously lives on its charging coaster, offering about 80 minutes of cord-free use . The VSITOO heated coffee mug rechargeable battery, by contrast, is a marathon runner. On a full charge, I get a consistent 3.5 to 4 hours of active heating. This means it lasts through my entire morning deep-work block, from 7 AM to my lunch break, without a single thought about power. It provides true mobility around my home and home office. Furthermore, the 316 stainless steel interior of the VSITOO is a practical win over the ceramic coating of the Ember. It doesn't stain, it's easier to clean, and it feels more resilient against daily wear and tear. The dry-boil protection is another intelligent feature. I can't count how many times I've been pulled into an urgent video call and returned to find the mug has safely powered down, preserving both its components and my peace of mind. In conclusion, the VSITOO S3 has seamlessly integrated into my life. It has eliminated a daily micro-frustration I didn't realize was having a cumulative effect on my morning ritual. It’s a device that doesn't just promise smart features; it delivers them with robust reliability and thoughtful design. For any tech enthusiast or anyone who views their coffee ritual as sacred, this temperature control smart mug is an unequivocal recommendation. It has outperformed my high expectations and proven itself to be a mature, well-executed product that genuinely enhances my day.

I’m going to be really honest whit this product, I’m going to start whit the pros. Good presentation, good packaging, and thats it :/ looks good on the first glance but once you start using it all you want to do it’s just go for a good cup of coffee. The cup it’s to small, you have to chose the 6oz. Or 8oz . Or it will spill once you add your creamer, and something else, we never find out if it was working right, I have a smart mug and my co workers too, so it’s not our first time using this cups and none of us was really sure on what to press to make it work. It was a gift and I feel embarrassed to be honest. I just returned and order an ember for almost the same price :/

TL;DR (Quick Summary) Power button is inconsistent and requires lifting the mug, which can risk spills. Included lid is very loose — pops off easily and doesn’t seal; not usable. Heat settings max out at 130°F, not the advertised 150°F. Stays warm only if the lid is on and the drink starts at least at 130°F. Battery doesn’t “power save”; it simply dies around the two-hour mark. Works best only when left on its charging base. Great only for people who drink one hot beverage within a two-hour window. Recommended upgrade: Yeti Rambler MagSlider lid (medium, 3.5") for the 14oz mug. (Link below) FULL REVIEW: I really wanted to love this smart mug, but it just didn’t work for me. The power button is inconsistent—you have to lift the mug to reach it, which risks spilling if you’ve already poured your drink. Sometimes it turns on with one quick press, and other times you have to hold the button for a few seconds before anything happens. The lid was also a disappointment. It barely fits, has no suction, and pops off with almost no effort, so I didn’t feel comfortable actually drinking from it. I ended up using a Yeti Rambler MagSlider lid instead (the medium size, 3.5"), which worked perfectly. The listing says the mug heats up to 150°F, but the highest setting is actually 130°F. If you pour in 150°F water, it will cool down to 130°F. The temperature also only holds if the lid is on. With the lid on and the drink starting at least at 130°F, it does stay at a pleasant, drinkable temperature—but only as long as the battery lasts. The advertised two-hour life isn’t really a power-saving feature; in my experience it simply runs out of battery and shuts off. Because of that, the mug really needs to stay on its charging base to be reliable. For someone like me—an ADHD “power tea drinker” who likes two cups back-to-back and tends to leave mugs around the house—this setup just doesn’t work. I wanted something I could walk around with and come back to later while still having a hot drink. That said, if you're someone who drinks one hot beverage within a two-hour period and doesn’t need another for several hours, this might actually be a great mug for you. Just be sure to get a different lid—I highly recommend the Yeti MagSlider. https://a.co/d/fWvnRdS

Game-Changer for Hot Drink Lovers! I’ve been using the VSITOO Temperature Control Smart Mug S3 for a few weeks now, and I’m genuinely impressed with how much it’s improved my daily tea routine. The temperature control is incredibly accurate—no more rushing to finish my drink before it cools down. Whether I use the manual controls or the app, adjusting the heat is effortless and surprisingly fun. The rechargeable battery is a huge plus. It lasts longer than I expected, and the mug keeps my tea warm for hours without needing to sit on a base. The LED light indicator is a nice touch too—simple, modern, and intuitive. The included lid is great for keeping my tea hot even longer, and the overall build quality feels premium and durable. I also love the sleek design; it looks great on my desk and is comfortable to hold. If you’re someone who’s constantly reheating your tea, this mug is absolutely worth it. The VSITOO S3 has genuinely upgraded my everyday routine—highly recommended!

I was really intrigued about this smart much and was excited to see how it may help me. I have a busy job and find that my coffee often goes cold so this was exciting as it possibly offers as solution. The device is really sharp in appearance. It looks well made and of high quality. It comes in three parts, consisting of a base, a mug and then the watertight lid. To use, the mug can be used on the base whilst charging or away from the base. By downloading the app and linking your phone to it, you get a wider range of settings and the ability to track the temperature. The app however is a bit glitchy and adding the mug was quite frustrating. After a reinstall though it finally worked. When you set the mug to heat or maintain heat, the app tracks the current temperature and displays it on the screen. This is in addition to telling you what target temperature you have set it to. To try it out I made my coffee and have sat with it for over an hour. It’s still 57•c at the time of writing this review. Essentially as hot as I’d normally drink it. Overall it is a really good idea but to be very honest cold coffee isn’t the biggest problem and I do find myself questioning whilst it is good, is it needed? I believe that as it has the ability to maintain warmth and heat that this is a great mug for commuting or for those with jobs that demand their focus moves throughout the day. A good product and I would recommend it if you believe it is something that would benefit you. It is a nice to have item.

I bought this as a gift for my mother. Easy to use and looks good. Customer service were very helpful and easy to contact via WhatsApp. The lid is a nice touch that other similar products don't have. Pleased to say my mother is happy with this product.

On the plus side: The mug definitely serves a purpose. It is not a travel mug nor is it a cup warmer that you can set your mug on and have it heat all day long. The Smart Mug does allow you to enjoy a leisurely cup of coffee (for an hour or so) that stays hot to the end. Or if you are a busy mom you can drink your coffee on the run in between distractions and demands and not be drinking it cold when you reach the end. (Incidentally, I had a couple of cup warmers and realized how dangerous they are when I noticed a burning smell coming from one of the rooms. They are definite fire hazards and I don't recommend having them around small children. They went in the garbage.). On the negative side: We have two Smart Mugs now and the lids do not fit tight on either of them. I'm not sure if that is the intention or if we just happened to get two that don't fit. Also, the instructions could be a bit clearer and more detailed. It is obvious they have been translated to English.
