WTF – USB Cup Warmer

October 25, 2014

And now for something that we’re going to get immense usage out of: a Coffee Mug warmer! OMG! This is so brilliant. Honestly, we were really skeptical when we first looked at this thing, and we were totally surprised at how well it works. It actually got too hot to touch. This will actually keep your coffee warm. And I’m sure coffee shops won’t like it, because it’ll mean you’ll drink your coffee for longer instead of buying another coffee. I don’t mind. I’d like to get a bunch of these and have them available for people at our cafe. It’s good for studying!

What’s the science behind this thing? I didn’t think that it was going to get so hot. Help me science this: my laptop doesn’t get this hot, so how could the cup warmer get so hot? Is it because my laptop has a fan, and because the circuits are spread out, while this cup warmer doesn’t have a fan, and focuses all of its energy on…err…metal somethingadoodad? Sorry if this is an obvious answer. I was an artsy student, not a math or science one…

Also, did you see our mug in the video? We’ve got special mugs we made just for our cafe. We don’t sell em online. Martina made four designs. She obviously likes the one of her the most, but I think my beard one is pretty awesome.

Side note: our uploading game is strong this week! We’ve got two more things to publish tomorrow. We’ve even got some of our Music Monday planned. WE’RE ON FIRE! Actually, it just feels really good to be back in the swing of things, putting out videos and talking to you guise. Touring is fun and exceptionally rewarding, but we’re a lot more comfortable hiding behind cameras and computers :D

  1. I have a couple of mug warmers that just plug into a wall outlet, but I use them for scented candles…candles melt, scent releases, and no fire.

  2. Yes yes! Great for Inuits, astronauts, cosmonauts, taikonauts, spacionauts and everybody else in Korea freezing their places-where-they-usually-brand-cattle off to turn Frappuccino into Cappuccino!
    Lady, it works as follows – it’s like a lightbulb, but without light. So more heat and slightly less light, like, lot’s less light. And yes, it does empty your laptop battery into the void, so plug in rather than run off battery.
    And as for fire, if you can create fire from it, that would be amazing, but yeah, but no, but yeah, but no. It’s probably not going to really warm your coffee up too much (2.5 watts? meanwhile, a full-blown electric coffee maker’s warmer plate is 250 watts…), but then again, it won’t likely kill your USB slot either – USB slots die these days from wiggling loose or from something going very wrong with the four lines inside of them – they have pretty good overcurrent protection these days.

    Science!

  3. Simon, I’m with you! I also always always drink cold beverages. For making coffee at home, I use a Toddy system and brew enough coffee for 4-5 days at a time. There is always a huge canister of coffee nice and chilly in my fridge. Any time I have a hot beverage I burn my tongue, I’m too impatient.

  4. *raises hand* question does this work only for mug or do you think it will work for paper cups because I don’t know if people do this but I don’t carry around a mug everywhere I got for my coffee/tea. Or is this more like a at home thing.

  5. Just wanted to say that you probably can use an old ipod chargher thing. The one that is the plug part with a usb port. I used it with a friends speakers which gets its power thru usb from computer. You should give it a try and let me know if it actually works!

  6. But what if it catches on fire? I know that’s highly unlikely, but it’s still possible. I mean, that usb cup warmer must use up a lot of a computer’s battery to function. Btw love the mug ^_^ Where’d you get it?

  7. I love Martina’s mug! As a coffee lover I totally see why the USB cup warmer is useful and how awesome her mug is! >.<

    I feel like that would drain your battery, does it?

  10. Dang… I was just at yoooo coffee shop.. I gots a green tea latte. Pretty good! Your directions made it super easy to find. It’s funny to see it in a video now. I’m all “I was just there!” I’m still in Seoul… so I’ll probably stop by again. whoo hoo.

    I’ve seen this online! I’ve also seen the USB humidifiers and I’ve always wondered if those worked….

    Also HAVE YOU TWO SEEN THE AGE OF ULTRON TRAILER?! AMAZING!!!!

  12. I would like to put this as gently as possible so you don’t feel attacked, but I think it would be best if you didn’t use the word “eskimo” because it is considered a racial slur. Their proper name is Inuit. While people aren’t exactly sure of the word origin, it is thought to be derived of a Cree word that means “eater of raw flesh”. It is sometimes used to imply that the group is made of cannibals, which is clearly not the case. I’m sorry if you feel as though I am overstepping my boundaries, but I felt that it was necessary.

  15. I want one!! So so so bad! I always drinks insanely amounts of tea when I’m studying and writing essays and my accommodation forbids us to have kettles in our rooms *sad* so I always have to make my way to the kitchen which, while it does provide a nice break at times, also gets annoying. Especially since I drink my tea very fast as I cannot stand drinking cold tea. My current strategy though is to keep my thermos flask filled up with hot water. It gives me 2 extra cups of tea for every trip! But having this could still make it last even longer!

  16. Haha, having to flip the USB over a bunch of times before getting it right, I know that struggle. I’m so proud of you Martina for getting it correct in your first try.

  17. Hey guise! I know it’s off topic, but I love Martinas hat!! <3 Did you buy it, or is it homemade?

    5 years ago
    • Actually, great story about the hat: Martina had one just like it last year for our European tour, but then she lost it on tour, and was very sad about it. This year, one of the organizers from our Norway event made this hat to look just like the one Martina lost. IT WAS SO TOUCHING WE ALMOST CRIED.

  18. This is a really wonderful treasure find!!! :D

    And really thank you guise so much for you hard work, jumping right back to work just after your trip. Just wanna let you guise know we really appreciate it! ^O^ Can’t wait for rest of the videos!

  19. “Yeh, but I want to see if it gets warm before I put a coffee on it…” Oh, Martina. I’ve had those conversations. Best the hand gets burnt first in case the coffee does. Priorities!

  20. The easiest answer is that it gets hot because it’s designed to. Your laptop isn’t designed to get hot, it’s just that heat is an unfortunate byproduct of its doing business and it’s great at cooling. Unless there is some kind of weird space magic going on there, there’s no functional difference between an electric heater or range and that cup warmer. The long answer as to why the computer draws way more power yet doesn’t explode while the heater draws less and is too hot to touch isn’t too complicated. It’s just super long and I would be like…50% talking out of my ass and at least 20% sleep deprived delirium that makes me ramble like an old man. At any rate, it shouldn’t affect your laptop in any way beyond discharging your battery a little quicker. I would be real curious about what kind of power it’s drawing though. Not out of any worry…just curiosity. I can’t imagine this thing drawing more than an external hd or quick charger. Does the box or heater show any wattage number?

    Oh yeah, cold beverages year round. Scalding hot drinks? That’s for the masoch – people whose decision to drink hot drinks is one I totally respect.

    • To add to his comment, don’t forget that metal conducts heat very easily whereas laptops are insulated as much as possible to prevent fires and other bad things from happening

  21. This is actually a really great idea! I really don’t like my drinks tepid or room temperature. If it’s a warm drink it should be warm, or if it’s a cold drink it should be really cold.

  23. I tend to look at weird household stuff online, and I’ve actually seen other weird USB items…

    I’ve seen fans, humidifiers, hand warmers, massager, coaster, air purifier….

    I sometimes wonder how good these things are, but I see no reason to get any of those…

  24. So….could you use one of those to keep water thawed for feral cats??

  26. The only bad thing about those sort of doodahs is they are horrible for your USB ports. We use USB ports for charging things and whatnot, but they are actually not “meant” to handle lots of energy and eventually, this kind of usage burns through them much quicker than they should. Especially really power consuming things like heaters, fans and whatnot. :|

    • I think everyone eventually learns the hard way that USB ports can in fact die completely. Never trust USB gadget makers! Most importantly, probably not CE or UL tested.

  27. It’s okay Simon, I only like cold drinks too. I drink frappuccinos in winter and I live in Ohio. Your hand kind of freezes off if you’re outside but they’re delicious.

  28. Question: How long does it take to cool after use? I wouldn’t want to stuck somewhere because I had to wait for my portable USB coffee warmer to cool down. That sounds uber hipster… :P

    5 years ago
    • Great question! We didn’t have to wait for it, I don’t think. We finished filming, talked with some people for a few minutes, and then packed up and left. I’m assuming you won’t need more time than that :)

  29. I need one of these for my desk at work. I have a bad habit about forgetting that I’m drinking a hot beverage and by the time I remember it’s cold. This would be easy to just plug into my computer.

    At home, I’m to paranoid about having any kind of beverage around my MacBook. I’d have to use the plug connector and plug it into the wall. Great WTF find… wait that’s repetitive, isn’t it. Hmm.

  30. Oh man I need one of these in my life. Especially since I’m the only one in my family that likes hot tea.

  31. I want one now!

    Simon looks like he’s burning off his fingerprints to get ready for the perfect crime or something. ^^

  32. So I actually have something like this in my office… although it’s a candle warmer…or maybe it’s a cup warmer but we used it as a jar candle warmer because we’re not allowed to burn candles in our office… I don’t know…Any who, we had something like this that melted candles and it worked really well! But..I think it plugged into the wall outlet…so I guess not exactly similar but similar enough that I’m not going to delete my ramble!

    But..with it plugging into your laptop USB, wouldn’t that drain the battery? You would think that it would be pulling a ton of power from the battery supply to warm up so if you’re constantly looking for an outlet to charge your laptop, is it worth it? I guess as long as you have hot coffee (tea in my case) while you charge your laptop it’ll be cool…warm…ALL GOOD!

  33. I own one of these, but mine plugs into the wall rather than the computer. But mine’s on its last leg, and I kind of think I miiiiight need one of these instead. Because it’s BLUE!

  35. This is actually way cool! Currently looking for work, so, I can’t buy now but soon! lol I’m like Simon though, love cold drinks even in winter but I’m a writer and I like to write outside in winter. A warm cup of coffee is perfect for this! And I can’t stand a lukewarm drink, just… eww. This would work with hot chocolate too!

  36. I so need to snag one of those!

  37. What if you have to dash and the warmer is too hot to put in your bag again? And would it drain the battery from your laptop? :O

  38. I live in SC and I’ve seen those around… Well in the store I don’t know anyone who has one. Maybe because SC is generally warm, winter is fairly short. Summer is forever, and extremely hot and humid.

  39. I think the “science” behind this is that the laptop acts as a battery/electric source. So the device itself is wired so that it’ll get hot as long as it has electricity. It’s as if you’re plugging the warmer into a wall outlet.

  40. Finally, something to keep my cup of tea warm! Where did you buy it?
