Vsitoo S3 Pro 16oz Smart Self Heating Coffee Mug, Heated Coffee Mug with AI Auto-Sensing Temperature Control, 120-150℉ Rechargeable Smart Mug Warmer, IPX7 Waterproof, Gift for Men Women, Black

Let me paint you a picture of my pre-VSITOO life. I transitioned to working from home full-time over five years ago and while I love the flexibility, it completely destroyed my coffee ritual. I'm a coffee enthusiast. I grind my own beans, use a precision brewer and the entire process is a morning meditation. But then, reality would hit. I'd pour that perfect, steaming cup of coffee, carry it to my desk and take that first, glorious sip. And then, the inevitable would happen. An urgent email would land and I would get sucked into the vortex of work. I'd return to my desk, reach for my mug and be met with the profound disappointment of cold coffee. My solution? The microwave. I knew it was a cardinal sin, a practice that utterly murdered whatever flavor remained, but I was desperate. This was my daily cycle: brew greatness, then systematically destroy it. I knew about smart mugs. A colleague had an Ember Mug 2 and swore by it. I was tempted, but the reviews about its short battery life and fragile ceramic coating gave me pause. It seemed like a product with a great idea but flawed execution. Then, during a deep dive into alternatives, I discovered the VSITOO S3 Pro Smart Mug. The specifications stopped my scroll: dual-walled 316 stainless steel, a scratch-resistant coating, a promised 2-4 hour battery life, and an IPX7 waterproof rating. This sounded less like a fragile gadget and more like a serious piece of equipment. The mention of it being a heated coffee mug rechargeable via USB-C was also a plus. I decided to take the plunge and I can say, without a shred of hyperbole, that it has fundamentally transformed my daily work life. The unboxing experience immediately set the tone. This wasn't packaged like a disposable gadget; it felt premium. The mug itself, in the matte black finish I selected, was a vision of understated elegance. The first thing I noticed was the weight and solidity. It has a satisfying heft that communicates durability without being cumbersome. The dual-walled 316 stainless steel construction isn't just a bullet point on a box; you can feel it. It feels robust, like it could withstand the minor bumps and knocks of daily life. The exterior coating is smooth yet grippy, and it just feels expensive. The lid was a particular point of admiration. It clicks into place with a definitive, resonant snap that screams precision engineering. I conducted an immediate leak test—vigorously shaking it over the sink—and not a single drop escaped. This was a heated travel mug built for the real-world journey from my kitchen to my home office, not just for sitting statically on a coaster. The true magic, however, begins the moment you pour your coffee in. The built-in AI sensor is so seamless it feels like witchcraft. There is no fumbling for a button or opening an app. You simply pour your freshly brewed coffee and within seconds, you can feel a gentle, uniform warmth emanating through the mug's walls. It’s an "it just works" moment that is incredibly satisfying. I am a creature of habit and I've found my sweet spot at 142°F. It's hot enough to feel deeply comforting and release the aromatics, but cool enough to sip comfortably without any scalding. Using the single-touch button on the mug's base is intuitive; a quick press cycles through the temperature presets and the LED indicator is clear and unobtrusive. While the physical button is fantastic for quick adjustments, the Vsitoo app unlocks another layer of precision. Pairing was instantaneous. Through the app, I can set the temperature to the exact degree, monitor the real-time temperature of my beverage and most importantly, extend the auto-shutoff timer to the full 4 hours. Watching the app maintain a perfectly straight line at 142°F is a thing of beauty for a data-driven person like me. The smart temperature control is the star of the show. It’s not merely "keeping it warm"; it's actively maintaining a precise, optimal drinking temperature. For the first time, my coffee is not just a beverage that starts hot and ends cold; it's a consistent, perfect experience from the first nuanced sip until the very last, even if that last sip is two and a half hours later. This is where the comparison with my colleague's Ember Temperature Control Smart Mug 2 becomes inevitable. The VSITOO S3 Pro isn't just a competitor; it feels like a generational leap. The most significant advantage is battery life. My colleague constantly laments how his Ember mug needs its charging coaster after about 90 minutes. The VSITOO, on a full charge, consistently delivers 3.5 to 4 hours of continuous heating at my preferred temperature. This is a monumental difference. It means I can go through my entire morning deep-work session without a single thought about power. The switch from a ceramic-coated interior to the industrial-grade 316 stainless steel is a game-changer for maintenance and longevity. His Ember stained easily and eventually chipped. My VSITOO wipes completely clean with a simple rinse and shows zero signs of wear after two months of heavy use. The scratch-resistant coating on the exterior is equally impressive; it still looks as pristine as the day I unboxed it. The intelligent safety features provide a profound sense of peace of mind. The dry-boil protection has activated on at least three occasions when I was pulled into a marathon conference call and forgot I had finished my coffee. I returned to my desk to find the mug cool to the touch and a notification in the app. It’s this thoughtful engineering that elevates it from a simple coffee cup warmer to a truly smart appliance. It protects itself and by extension, my desk and home. The automatic shut-off, which I have set to 2 hours for safety, means I never have that nagging anxiety that I've left an electric coffee mug on while I've stepped away. In conclusion, the VSITOO S3 Pro has done more than just keep my coffee hot. It has restored the integrity of my morning ritual. It has given me the freedom to become immersed in my work without sacrificing one of my life's small, daily pleasures. It is, without question, the most impactful and satisfying product I've purchased this year. For anyone working from home who views their coffee as more than just caffeine, this self-heating coffee mug is not an indulgence; it's an essential tool for a better quality of life. It has made my previous skepticism about smart mugs feel utterly foolish.

I have a complicated relationship with "smart" devices. For years, I dismissed the entire category of the smart coffee mug as the apex of unnecessary luxury. A heated mug? It seemed like the ultimate first world problem. My coworker, a man I respect deeply, had been a longtime user of an Ember coffee mug. While he enjoyed it, his complaints were consistent: "It's a bit delicate," and "I wish the battery lasted through my long lectures." When his department got a few VSITOO S3 Pro Smart Mugs for a product testing lab, he brought one over to me. "Try this," he said. "I think this is more your speed." He was right. After one week of using his lab sample, I immediately ordered my own. My initial impression was that this was a tool designed for an adult. The VSITOO S3 Pro has a utilitarian elegance that appealed to me instantly. The brushed stainless steel version I purchased is stunning. It lacks any flashy logos or gimmicky design elements; it's all clean lines and profound solidity. The premium construction is palpable. The 316 stainless steel feels indestructible and inert, promising no flavor transfer. The IPX7 waterproof rating was a major selling point for me, as I often rinse my mugs hastily between cups. Knowing the electronics are fully sealed against water damage is a significant relief. The lid, with its secure locking mechanism, is a masterpiece of design. I can toss this heated travel mug into my leather briefcase alongside my books and laptop with absolute confidence. It has survived being knocked off a lectern by an errant cable onto a linoleum floor without a dent or a scratch, a testament to its scratch-resistant coating and robust build. My daily routine is a perfect crucible for testing any temperature control mug. My days are busy, solitary research hours and back-to-back. Before the VSITOO, my coffee consumption was binary: I would either chug it quickly before a commitment or abandon it to its cooling fate, only to rediscover it later as a cold, forgotten relic. This self heating mug has revolutionized that dynamic. My new ritual is simple: I brew my tea or coffee, pour it into the mug, and set my desired temperature via the tactile single-touch button—138°F for my black tea, 145°F for my afternoon coffee. I can then walk to a 90-minute faculty meeting, and here is the miracle: when the meeting concludes, my tea is still at 138°F. It is not "warm." It is perfect. The smart temperature control is so precise that it preserves the entire character of the beverage. A delicate Darjeeling doesn't get stewed; it remains floral and nuanced until the final sip. The comparison to the more well-known Ember Mug 2 is not just favorable for the VSITOO; it is stark. The reliance of the Ember on its charging coaster feels like an archaic limitation. The VSITOO S3 Pro, with its long-lasting internal battery, offers true freedom of movement. I can carry it from my office, to the library, to a seminar room across campus, and it is a self-contained, perfectly heated system. The promised 2-4 hours of heat is not marketing fluff; I consistently achieve a solid 3.5 hours, which is more than enough to cover even the most protracted academic deliberations. As a heated travel mug for navigating a large university campus, it is peerless. Furthermore, the durability is in a different league. The stainless steel interior doesn't stain or retain odors like the coated interior of my colleague's older Ember Mug. This heated coffee cup is built not for a product lifecycle, but for a decade of daily use. The AI sensor that automatically initiates heating is genius precisely because of its simplicity. You do not need to be technologically adept to use this mug. It possesses an intuitive intelligence. The coffee cup warmer functionality is entirely autonomous. And the critical safety features the auto-shutoff and the dry-boil protectionism mean I operate with zero cognitive load. I never worry about leaving it on. It is a truly "set it and forget it" device that delivers relentless, unwavering performance. This temperature control smart mug has transcended its status as a gadget. It has become a seamless, integrated part of my professional life, a small but profound pillar of consistency and quality in an otherwise chaotic schedule. It is a product that earns its five-star rating not through flashy features, but through flawless, thoughtful, and robust execution.

I've been using this for about a month now at work. I work in as tech at an art school, and am frequently called on to rush to one of the 8 or so buildings to fix things unexpectedly, so my solution was a smart mug or thermos - I've used thermos' before and they work great but are hard to clean without a dishwasher, and I wanted something I could leave at a specific temp if I needed to run out quickly without my coffee cooling off too much. This works almost perfectly for my purposes. Is it worth 100ish bucks? Probably not. Your coffee will stay hot for 8 hours or so in a thermos type container. But if you think it's cool, go for it. The software for android works, but it's kind of a hassle and was fidgety with setting specific temps and when I get to work I don't want to open an app and connect to BT just to drink my coffee. I found it easier to just hold the button under the mug down (AFTER adding coffee - it will auto shut down if no heat is detected, a feature I do like) which powers it on and will restore the mug to the temperature you had selected when you powered it down. I like that it remembers. Touch control is a bit skittish but works well, especially after I updated the firmware - which works via bluetooth in the app - it took me about 30 tries before it fully downloaded and installed. Maybe network interference. The settings are written in Centigrade, not Fahrenheit, which can be confusing for those unfamiliar. I found keeping the touch light button set to 55C (131F) was the perfect drinking temp. It goes up two more notches, up to 65C, which to me was a bit too hot. 55 or the next step up are the settings I find to be most comfortable for me. You can use the app to dial in a specific temp in theory but the notched touch setting works good enough. You can use the mug off the charger, but I keep it on my desk because I never really take it on walks. The charge time appears to be sufficient. The mug will shut off if it detects that there's nothing in mug to heat up (eventually), to protect the circuitry inside. It can be washed by hand quickly and easily. The metal with enamel coating is fine, but the handle came with a tiny chip in it (I highlighted the chip in the photo - it's blurry) small issue for me, considering an alternative Ember mug is about 50 bucks more than what I payed at the time of purchase, but paying 100 bucks for a fancy mug and the first thing I see is a tiny chip in it was a bit unsettling. Maybe I'm just unlucky. That said, the packaging was a near-Apple level experience, making me feel like it might be a massive waste if the mugs are still going to come chipped. I'm a critical person, but these things are very small when considering the value and performance, in my opnion. The handle of the mug is wide enough to hold comfortably, but has no "meat" to it due to probably trying to make is less heavy, but once you get used to it isn't a problem. It'd be nice if the handle was more ergonomic in some way, but not really a big deal. The mug is fairly heavy, but not much heavier than a solid, decent ceramic mug. The charger is proprietary as far as I can tell, which is a bit annoying since I often want to bring the coaster charge plate and mug home for a long weekend but wrapping up the charger is a hassle. I have many GaN and smart chargers from wattages going to 120W+ so I don't understand why I need to use THIS usb-C charger. A bit annoying but minor. I really really like this mug. It's not without it's minor flaws, but I found most of them to be small enough to give it a pass. It keeps my coffee where I like it, and looks pretty sharp, and that's worth saving 50 or so bucks! I say if you're thinking about it, give this one a solid try - worst case, you return it if you decide it's not for you. Update: My mug just randomly stopped charging up. The light comes when on the base, but it doesn't seem to be taking a charge. I'm not sure what the deal is but now I own a very expensive not-great mug. Just buy an embr.

This Vsitoo S3 Pro 16 oz. mug is exactly what I needed. I own the S3 12 oz. mug for morning coffee during weekdays and the S5 16 oz. travel mug for commuting. They both work great, easy to use and piping hot coffee for over 2-4 hours. I decided I needed a larger mug for leisurely weekend coffee, so I purchased the larger S3 Pro. 16 oz. I should add that I always brew directly into these cups to get the best quality from beans that I roast and grind myself. These mugs all just work, performing as advertised, and frankly exceeding my expectations from using other heating mugs. You don't need to worry about the electronics in these when washing, as the rating is IPX7, meaning they are waterproof to 3 feet for at least 30 minutes. Definitely recommend.

I have both the VSITOO S3 Pro and the Ember 14oz. Here is a comparison and review. CAPACITY: VSITOO says it can hold 360ml which should be 12.2oz but actual measurements show that it can hold just slightly more than the Ember 14oz. It is also bigger physically, and so is it's charge coaster. BUILD QUALITY: The outside of the S3 Pro feels very similar to the Ember's ceramic shell. The Ember beats the S3 Pro in that the inside of the Ember is also ceramic coated while the S3 Pro's is more like an enamel finish. Both of them have this thin uncomfortable handle. The Ember charge coaster is all metal (maybe except for the bottom that is covered with a rubber pad). The S3 Pro's coaster is metal on top and looks and feels like the Ember's. The bottom is plastic and has this ring texture that makes it difficult to clean. POWER: The S3 Pro coaster uses a USB-C port and I would assume you can use any power supply that is rated "USB PD" (power delivery) that can supply similar amperage (2.1A on the supplied adapter) to power the coaster. The Ember on the other hand, uses it's own 19V power supply with a barrel connector. Both coasters are always on, meaning even without the mugs resting on them there is 19V at the "pogo" pins you see on the coaster. This means that if you rest a metal object across those pins you'll cause a short circuit most likely damage the adapter. CHARGE CAPACITY: In regular use, I've found the Ember to be able to keep working for almost 2 hours on a full charge keeping my coffee at 140F. In it's ads, the S3 Pro says it can keep going from 4-8 hours but so far I have yet to see it make it to 2 hours. APP: The Ember app is very basic. You're supposed to be able to set a color for the LED to identify your mug when there are other Embers around but that function has never worked for me. The LED is always white. The Ember app also never connects to the mug reliably or consistently. I've had to delete and reconnect my Ember at least 4 times since I got it. I've just given up and just let the mug keep my beverage at whatever temperature it remembers. The S3 Pro app has a lot of potential. BUT why does a smart mug app need so many permissions??? For it to work, first it needs permission to access phone functions. Then you need to give it your phone number to which it sends a verification code. Then it needs access to media storage and, strangest of all, location! I denied all permissions and it wouldn't connect to the S3 Pro. Within 24 hours of installing this app I got a text message saying "XEsn acrazygirl.???.*567". (I replaced some stuff with question marks for safety.) Coincidence? Maybe. But when something that just needs to connect to a mug to tell it what temperature it should be at needs access to so many unrelated functions it makes me very suspicious. Also, I live in the US and I'm used to having my temperatures in Fahrenheit. I switched the units to F and now the scale switched from increments of 5 deg Celsius to increments of 9 deg Fahrenheit. Yes, they are regular increments but they seem arbitrary on first glance. Why not just use 5 degree increments in both C and F? CONCLUSION: Despite the build quality of the S3 Pro's coaster, it's inner coating, and lackluster charge capacity, I think I'll be using it more. That means it'll be the mug I leave at the office because I'm there more than I'm home. If I ever travel, the S3 Pro will be what I take with me. The fact that you can adjust the temperature on the mug itself without having to open an app is a big plus. (I've uninstalled the VSITOO app.) At a cost of $30 less than the Ember I think this is a great value and something I should've given as presents last Christmas instead of the Ember. UPDATE: 10 months later, my S3 Pro is completely dead. The LED started blinking red and then it stopped. Now it no longer turns on. I was hoping it would come back to life if I left it to discharge completely before recharging it but it no longer charges. I used the S3 Pro and the Ember about the same duration every day and the Ember still works. I'll update this review again when the Ember dies.

I didn’t think I needed a smart mug until I actually started using one, and now it’s part of my everyday routine. I’m the type to pour my coffee and then get sidetracked, so it usually ends up cold before I even remember it. This keeps it at the perfect temperature the whole time, which makes such a difference. The build feels really nice, and the design is minimal but still looks elevated. Personally, I think It’s so pretty in person. What stands out is how simple it is to use. There’s nothing to adjust or figure out, it just works. And I like that I’m not stuck keeping it on a charger, I can move around with it and it still does its thing. If you drink coffee or tea daily, it’s one of those little upgrades that ends up being way more useful than you expect. I think I’ll get my mom one for Mother’s Day too 😁.

This mug is an exceptional. I can always enjoy my warm coffee. So far this mug is working great with Stainless steel. Few glitches on the app, but overall it's good.

I got this on a Saturday and it would not turn on/off with the button on the bottom on Sunday. It has been returned, but I did get to use it 5 times and writing the review off of this. My star rating is not figured due to breaking as any electronic can break (although a $100 mug should be better built). Pros: *Using hot coffee at the start (never got to test/try heating up cold coffee in the mug) it lasted over 2 hrs each use at 55c. *It did keep my coffee at this temperature the entire time (I even did one beverage at 60c and it lasted over 2hrs and kept the liquid at this temperature as well the entire time). *Mug felt solid in my hand, made of good materials. Cons: *The app (it did not prompt me to share my contacts, etc. when I installed/used it) required me to give it my phone number or sign up via email (and it sent code, so you cannot skip this step). Its a mug, connect and work, I don't want to share my number/email with you and I don't want to be forced to do this either as its unnecessary other than they want your info. *The app stayed connected as long (as I opened it up and connected as soon as I powered on the mug) as it was open (I kept it open over 30 mins twice just to watch the temp). The instant the app was closed, it dropped connection and I was never able to reconnect other than the initial power on stage. *The power on/off button is at the bottom, on another of their products it's on the handle which proves it doesn't have to be where its at on the high end mug. When there is no coffee in the mug its fine, but once you have coffee in it, there is a problem if you need to access this. *While you can toggle between C/F, on both the mug and in the app where you adjust it, you can only pick selected spots (5 degrees Celsius increments), while this was "close" to my desired temp I should be able to pick any temp. *Saucer - I wound up putting it on my desk as later in the day, I like to have a cup of coffee that I will sip on for a long time (in the past when it got cold in my Yeti, I would pour it into a glass cup and microwave it, then back to the Yeti it went) so being able to keep it in the saucer where it could stay on/heating for longer than the battery would last was desirable, it was a bit too big on my desk (or beside my coffee maker). *Saucer & Mug - Not being wireless charging, there are 2 negatives about this, first it should be fast charging (come on, its usb-c connected with a supplied 110 charger) but even on a hundred dollar mug they didn't build this in. Secondly, while its not an issue with the mug, the charging points are prominent on the saucer and could easily short out or water/tea/coffee that may run down the side of the mug while drinking would pool in this area. *Capacity - While 14oz is much better than the earlier 10oz size, you still don't fill it to the rim (if your using the cap, which I would assume most do as you don't want to knock it over and spill out your coffee on your desk) you don't really have 14oz. A latte with 8oz of milk, once you froth the milk and add a double-shot espresso, it will not fit... All in all, if this was half the price and didn't break I could overlook the negatives and keep/use this mug, and was debating on keeping it at the price I paid. It breaking made it a super easy decision, back it went for a refund and not a replacement. This product could be so much better and once it gets there, I will get another, but we are not there yet.

Very good for work time, the quality is good👍🏼

O vendedor cumpriu exatamente o descrito. Dele eu não tenho o que reclamar. Já o produto achei bem ok considerando o valor. Bateria dura pouco. Toda vez que você usa, tem que carregar. Para manter a bebida quentinha, tem que manter a temperatura no 60, se não a bebida fica morna/temperatura ambiente. Na primeira lavagem, a tampa já ficou manchada, isso que nem usei a parte abrasiva da bucha, usei a parte macia. Resumindo, o produto funciona, mas não é essas coisas todas. Não compraria novamente.

Tuve que comprar una segunda por avería en la primera. Pero me han ofrecido un recambio. Estoy muy contento con el producto. Es genial y perfecto para la oficina.

This product stopped working in less than four months ! It won't charge any more and these kind of Chinese products aren't easy to repair any where. Nor the seller or the company care to respond or provide feedback ! And the supposedly touch button never ever worked !

Lovely mug very happy
