Impulse Induction Stove: boils water in 40s and has backup battery for outages
- solfox 3y agoBattery power also enables 120v use, which is great for retrofits.
- lbourdages 3y agoThis is definitely the main reason behind the battery. Being able to cook during a power outage is nice and all but it doesn't justify the very steep price all by itself. I have a cheap camp stove I can use for the rare times it happens.

- Glyptodon 3y agoDoes the battery mean there's a max "burn time?" If so, what is it?
- hallway_monitor 3y agoWhat a beautiful application of this technology. 10kw output on quick boil mode? Yes please. I paid for all 50 Amps, I'm going to use all 50 Amps!
- hwbehrens 3y agoThe battery isn't the only interesting thing here, either. Thermocouples in the burners and magnetically attached physical knobs are both big quality of life improvements that probably don't have a huge impact on cost.
- searchresults_ 3y agoYES! The thermocouples are such a big deal. I have been using the Breville Control Freak cooktop ($1500, single 1800w burner) for years — this was the first device to include this feature. Once you use temperature-controlled cooktops, you can't go back. You can set your garlic to saute and walk away.
- jitl 3y agoI have a tiny NY apartment with ancient wiring, no 240v plugs. Upgrading would be a massive operation requiring cooperation from all the units below mine down to the basement - plus probably $50k or more. So compared to that, $5500 for an induction stove that also had 3x the performance of the average induction stove and 5x the performance of most gas stoves looks like a really good deal.

- PNewling 3y agoDo you not have 120v or is your 120v not stable enough? Because from the site it looks like it works with both 120v and 240v: > Designed to fit inside most standard countertops and work seamlessly with 120V or 240V connections.
- danbruc 3y agoNot sure what exactly ancient wiring implies but at 120 V this thing will draw 83 A to deliver 10 kW. CORRECTION: It only draws 15 A at 120 V, the remaining power comes from the 3 kWh battery. So you have 22 minutes of 10 kW until the battery is empty, then you have 1.8 kW
- jitl 3y agowelp, I only need like 40s to boil the water and like at most 5 min to cook something off at high heat in a wok, so 22 minutes seems fine
- OJFord 3y agoI think that's what GP means, that this is appealing to them because others at 240v only aren't. I'm not in the US so not that familiar (all my outlets are ~240v) with how it & appliances generally work and are marketed, but I assume the nominal 10kW is at 240, and that that drops (though it is still supported to work) at the lower voltage?

- 2Gkashmiri 3y agoWow. Heck. I bought one induction cooker on Amazon for inr 1300 or US $ 15.
- andreareina 3y ago> Best-in-class temperature sensors in every burner keep things dialed in. Imagine: no more burnt garlic or spaghetti water boiling over. That's not how it works.
- HumblyTossed 3y agoI saw that. I would love to see them demo this.
- deleted 3y ago[deleted]
- jeffbee 3y agoYou're right, especially the water example. However, an induction cooktop with a working closed-loop temperature control system would be nice. The one I own has a temperature control and it's anyone's guess what it's thinking. The outcome of setting the temperature control is completely random. Also, since my cooktop works on an extremely coarse duty cycle control it goes full power for several seconds and then is off for several seconds, which isn't even slightly helpful. A cooktop with better electronics that can modulate the power at high frequency, and control the temperature, would be great.
- ArchOversight 3y agoI have a high end Bosch induction cooktop which can modulate the power, and doesn't just do the on/off cycle that so many induction cooktops do to get to a certain power level. It feels more like a gas cooktop than anything else and it is fantastic.
- jeffbee 3y agoThanks for the tip. Unfortunately none of the review sites that I have found can be bothered to mention details like "can this be used to cook".
- OJFord 3y ago> doesn't just do the on/off cycle that so many induction cooktops do to get to a certain power level I don't have one any more, but mine did that; I never found it an issue - unless you're cooking with copper (solid, not the pointless/aesthetically clad stuff) or really thin aluminium I can't see that it's going to appreciably lose heat between cycles. Maybe mine just had much shorter periods than those that people complain about, I don't know.
- DrinkWater 3y agoI don't get it. What is so newsworthy about this, except for the battery which is included?
- lbotos 3y ago10kw stove output? "Novel battery usage". I don't know of another stove that uses a battery?
- DrinkWater 3y agoWhy do you need 10kw? I can boost my induction stove to 3.6kw if i need to and this is more than enough, my water also boils in seconds. I am not trying to be a hater here, but some of these features do not make a lot of sense to me.
- ovi256 3y ago> How powerful is the Impulse Cooktop? > With the integrated battery that can slowly charge up when you're not using it, and then quickly release that energy when you turn up a burner - there’s an incredible equivalent of 72,000 BTU/h of heating power, or 10 kW. (Compare that to 18,000 BTU/h for the best gas stoves currently on the market, or the equivalent of 28,500 BTU/h for some of the best induction stoves.) If the 10kW is per burner, that's a record. Highest I've considered is 5.5kW in two Bosch models (PIV975DC1E, 775, using a 32cm pot) that aren't sold anymore. Apparently not enough demand - most models are 3.7kW with boost. There are higher priced models that go to 7.3kW but that's a twin boost that works with an oven dish, not just a circular pot.
- throwawaaarrgh 3y agoThat's a fairly radical change, from 5 minutes to boil to 40 seconds. How is that even possible? If you pour water on a pot that's been dry heating for 10 minutes it'll boil immediately, but only the water that touches the metal and soon the temp drops.
- lbourdages 3y agoMetals have a very low heat capacity compared to water. When you preheat for 10 minutes a lot of the heat will just be radiated out.
- ravedave5 3y agoTechnology connections has a good video on boiling water. If you have a good way to dump energy into the water, it will boil fast. https://www.youtube.com/watch?v=_yMMTVVJI4c https://www.youtube.com/watch?v=_yMMTVVJI4c
- windex 3y agoAfter having dealt with electronics, what Iam really bothered about is serviceability. Tired of having to toss out stuff that cant be repaired or comes in sizes that aren't standard etc. I am ready to go back to wood stoves.
- lbotos 3y agoThe answer is going to "commercial grade". I recently bought a waring countertop oven (instead of a ninja/anova) because I could find replacement parts online (for now). I also did the same for a countertop induction burner -- commercial version had a replacement parts list in the manual with numbers for every part!
- throwup238 3y agoIf you can afford it the commercial versions are always superior to the consumer ones. The spare parts are available but at household levels of use, they’ll almost never break.
- floatrock 3y agoBuying a first-generation battery-laden appliance from a new startup in a category where my existing electric stove is about 20 years old and still works fine is quite the serviceability risk. Batteries are definitely disposables. Would love to understand what degree of standardization exists and what the replacement will look like after 5-8 years on this product. If there isn't a plan, their "sustainability" pitch is nothing more than greenwashing. I get this is for price-insensitive luxury early-adopters, but it would be nice if startups rewarded their early customers with something like extended warranties for the extra company risk they're taking on, especially with something expected to last 15-20 years. If these guys are around in 8-12 years, they will have ideally 10x'd their volume a few times by then so the extra warranty costs will be minimal. But most startups fail, so odds are this appliance will be e-trash then... would be nice to have some bonus reward for being the first to take on that risk.

- jacknews 3y agoThe battery work-around to low power mains supply seems it could serve a niche. Magnetic knobs seem like a great idea, and the 10kW max power level seems intriguing - I'd like to know what extra capabilities that allows. Otherwise, this thing looks like an expensive maintenance nightmare. Those lcd's will break. There's obviously firmware which will rot, and who knows if it's going to hang and start outputting 10KW while cooking your french omelette. Is the UI even usable, or a random cacophony of menus? The battery has a limited life, and will be taking some fairly punishing spikes, etc. I would be interested in some of these ideas in a more modular form.
- AlexandrB 3y ago> Otherwise, this thing looks like an expensive maintenance nightmare. Indeed. Our house has an electric stove from, probably, the 1960s. Complete with screw-in fuses. That's ~60 years of operation now. This thing will last 10 years tops. Their marketing talks a lot about "a sustainable future", but that doesn't jive with a future where major appliances have to be scrapped and replaced every 10 years or less.
- stickfigure 3y agoI have a similar electric stove, and yeah, it still delivers a terrible cooking experience decades later. We're going to replace it in a kitchen remodel soon. Induction is a better experience, and if it means replacing hardware every 10 years, so be it.
- jacknews 3y agoBut it doesn't have to be disposable. All the major components for induction cookers are commodified (coils, IGBTs, etc), it's simply a matter of making the whole thing more modular (particularly, separate the UI from the induction control), and for someone to make an actually-good induction control microcontroller/firmware package as a module.
- benzible 3y agoThere’s also Channing Street Copper which has an oven as well: https://www.channingcopper.com/ https://www.channingcopper.com/ - same concept with built-in battery. I’d love to see this idea applied to a tankless electric hot water heater.
- pierat 3y agoSo, the question needs asked: Do you need cloudshit to use this? We bought a stove that has this embedded cloudshit that wont let you use the whole oven for its intended purpose. And no way in hell I'm hooking it to a network.
- bogwog 3y agoI think it's safe to assume that the answer to this question is "yes". There's probably also a subscription service, and it's only serviceable by them. Consumer electronics have lost the right have the benefit of the doubt. So unless these things are explicitly mentioned on the product page, you should always assume worst-case.
- 83 3y agoCan you name the brand so we know never to buy from them?
- pierat 3y agoGE Cafe Appified bullshit is what it is.
- lbotos 3y agoI wonder how many pans this thing is gonna warp? Also -- a display in the center of the stove? Seems... like a bad place for it. I am happy to see competition in the space though and I hope more induction burners can get more accurate temp sensing and PID control I recently bought a https://www.webstaurantstore.com/hatco-irng-pc1-18-rapide-cuisine-stainless-steel-black-countertop-induction-range-cooker-120v-1800w/413IRNGPC118.html https://www.webstaurantstore.com/hatco-irng-pc1-18-rapide-cu... instead of a control freak as it has a temp probe and I wanted to see how well it worked. Haven't gotten around to seriously testing it yet but the plan is to mount their drop in 2 burner version in the counter if the probe works well.
- jeffbee 3y agoWhat's the fan like in that Hatco? I have a countertop induction cooker and I use it less often than I'd like because its fan runs full blast, at all times, regardless of the power setting. If I need to cook something at a very low heat for hours the fan noise is just too obnoxious to tolerate.
- lucideer 3y agoJust me or is the homepage basically unreadable due to scroll-hijacking? I can choose between hitting the arrow & getting halfway to the (faded out) next section. Or using the scroll wheel & skipping 3 sections at once. How do I read your homepage? Please help.
- ragebol 3y agoAre there any 'smart' appliances that can respond to what is happening in the pot? If the recipe says 'bring to boil, then simmer', then I want the smart stove to do that ~10 kW at first and automagically lower the power once the content is boiling.
- actionfromafar 3y agoThat's a great idea! A boost button, to run 20 seconds or something, would suffice for most needs. Or a boost "timer knob" for that tactile goodness.
- gampleman 3y agoThere are. My parents have an induction hob that sort of does that. I think the biggest issue with these kinds of "smart" features is the UI: you don't really want a hob that has dozens of buttons etc, that you don't understand, nor many menus with options, etc.
- akamaka 3y agoYes, for example: https://www.breville.com/us/en/products/commercial/cmc850.html https://www.breville.com/us/en/products/commercial/cmc850.ht... I’ve read many reviews of it and the people who have one claim that these precise temperature control features are the future of cooking.
- searchresults_ 3y agoYes, it is the future! Once you use one you can't go back. I can't use gas anymore after using the Breville Control Freak for years.
- OJFord 3y agoI had a pretty 'dumb' AEG induction hob that would do that. Sort of effective, but honestly I never used it other than figuring out how to do it once - combination of fiddly to do and just not something I personally think is that useful.
- catapart 3y agoAll of this looks awesome! I can't wait until the tech cheapens to make a consumer-class version of this available. Always nice to have some luxury items that are actually worth aspiring towards!
- lnxg33k1 3y agoWhats hackingly interesting about this? Seems more appropriate as a post on producthunt rather than here, or am I misunderstanding the site?
- jeffbee 3y agoAt this price it would never pay for itself, but an offsetting benefit of this battery system is, or at least might be, that for those of us paying time-of-use electric rates who also cook and eat dinner at dinner time, induction cooking is surprisingly expensive. If this thing can charge itself off-peak, and use its battery even when the grid is available, that could save a dime here and there. My summer peak-hour marginal cost is 54¢/kWh.
- ravedave5 3y ago54c is brutal, what's your off peak cost?
- zbrozek 3y agoIn PG&E territory- Summer peak: $0.61806 Summer off-peak: $0.53462 Winter peak: $0.51536 Winter off-peak: $0.48701 https://www.pge.com/tariffs/assets/pdf/tariffbook/ELEC_SCHEDS_E-TOU-C.pdf https://www.pge.com/tariffs/assets/pdf/tariffbook/ELEC_SCHED...
- rfwhyte 3y agoReally don't understand what about this thing makes it worth $6KUSD. Induction cookers aren't new technology, and batteries certainly aren't either. Just reeks of yet another "Tech" startup slapping a 1000%+ markup on their BoM because rich folks will pay whatever they're charging for the latest shiny gadget.
- xnx 3y agoSome good ideas in this concept. I hope the best ones are adapted to units 10% the cost.
- goldcd 3y agoI like the idea - but then wouldn't it be nice if your fridge had battery backup in case power went out? or your washing machine could charge cheaply overnight and run during the day? And then I start to think that maybe the better solution would be a smaller version of something like a powerwall. Maybe something flat that would easily fit behind the kick-board under the units in the kitchen and then could be wired up to provide multiple uses. Or maybe add a couple of sockets to that induction hob, that let you use it as a UPS for your fridge? Boiling water in 40 seconds might be fun, but doesn't strike me as a killer feature. Only time I've ever wanted a more powerful hob myself, is when I've got my wok out.
- conjecTech 3y agoThe benefit of building it into an appliance is that the device itself is certified, and you don't need an electrical inspection for just plugging it in. They mentioned adding a built-in outlet so that you could then have something else be on battery backup as well (fridge being the obvious application). I'm not sure if they ended up adding that for this version or not.
- tootie 3y agoA few things I'm confused by. For one 10kw would just instantly trip a breaker wouldn't it? Standard household circuits in the US are 110v at 15 amps which is 1.6kw no? A battery could make up the difference but it would either be huge or only last a few seconds. The temp measure is also a little confusing, but I'm guessing it's measuring the outer temp of the pan. That's definitely pretty good and comparable to a how an oven sets temp. I think it would actually be pretty amazing to include probes and set the temp based on the water or oil in your pot. In that case this would be functional as a sous vide cooker.
- 83 3y agoThat's one of the main selling points I think. With a 3kw battery in there you could supplement the output using the battery to reduce peak amp draw, then slowly recharge it later.
- ravedave5 3y agoI have experience with induction on an off-grid solar/battery setup, they are awesome and so much more efficient than old electric burners. A standard outlet is good enough for a single induction burner, it heats water faster than a junky microwave. Let me try my hand at some math around this, it may be wrong as I am a lay person. This requires 15amp service (from FAQs), so it can pull (120x15) = 1.8kw from the outlet. I will assume you can draw the 3kwh battery to 0 (good lithium/over provisioned). If this thing can output 10kw on a single burner, assuming no overhead for fans, which it will certainly need, it will be using 10-1.8 = 8.2kw from the battery, the rest coming from the wall. Battery is 3kwh. So it will be able to run for (3/8.2x60) somewhere around 20 minutes at this rate before dropping back to 120v outlet power. 20 minutes seems like not much, but that's cooking at an incredibly high heat. Stir fry needs like 3/4ths of that power, and it's done in ~5 minutes. A more likely scenario is you want to make a a nice spaghetti dinner but you are impatient, you have 3-4 pots going. Steaming carrots in one, boiling noodles in another, browning meat and also simmering sauce. So lets look at it as one 120v burner, plus 3 battery powered ones. If they also work at 1.8kw then the run time would be 3x1.8 = 5.4kw. 3/5.4x60 = ~33 minutes. In reality the steaming/noodle burners would need a ton of power for a few minutes, then only 1000watts. The browning burner probably needs 1200 and the simmering one 600-800. Seems like a pretty brilliant idea to add the battery. You suddenly made a single induction burner setup into a 4 burner setup. I have a hard time imagining a single meal that will get close to emptying this. The FAQ says if the power goes out you can make 3 meals on this stove-top. I have 4.8kwh worth of batteries and I can make ~2 days of meals (coffee/oatmeal, soup/hot chocolate, spaghetti) off the battery in winter, and run my lights, charge phone. I agree 3 meals would be easy, and I bet you could stretch to more if you were judicious. edit - fixed formatting.
- OJFord 3y agoIs there anything actually new here? It seems ridiculous, like it's trying to claim hobs haven't changed for 50y until this one, it's the only 10kW induction hob and a steal at $5.5k. I don't need to tell anyone induction hobs aren't new, and in a few seconds' searching I found Miele and Fisher & Paykel (i.e. not cheap brands) 8kW hobs well under £1k, I'm sure I'd find 10+ kW if I bothered a little longer. Seems like another example of 'what if we made a flashy website and a 'startup' out of something ordinary; pitching it as new, exciting, and high growth' to me.
- JKCalhoun 3y agoAgree. The site is, to me, almost a parody of what commerce of the 21st Century has become. It is so heavily targeting the affluent, Tesla-driving crowd, they might as well have added, "Get one for your yacht(s) as well." I miss the days when companies competed on quality and price. Edit: Also, aren't we all a little jaded by "Reserve yours now, coming in Q4!" I wish companies would go back to shipping already, then putting up the flashy web site.
- mihaaly 3y ago> "Reserve yours now, coming in Q4!" I only hope that they mean this year. ;) The sensationalist money collection for a non-existent inventions is something of a no go to me. Too many bad experiences collected by others in this regard throughout the past decades. Meanwhile, I can use that money now, for something I need now, on something that exists now. Interesting read and experimenting on others though.
- ravedave5 3y agoYou're using pounds, so you're in the UK - you have many more watts in a standard outlet than in the US. An electric kettle in the US takes over twice as long as one in the UK. Now try using that to cook a meal...
- OJFord 3y agoFwiw Gibraltar at least also uses pounds, but yes you're right I'm in the UK. This hob uses US 240v outlets if available (I suspect the nominal 10kW is not available otherwise, but I don't know) and surely you have electric ovens too anyway? A standard outlet as for a kettle though, yeah, absolutely. And in fact even in the UK oven/hob is usually on its own 32A circuit, which if you P=IV suggests 8kW is probably a common rating for a reason.
- ravedave5 3y agoOf course Technology Connections has a video covering this. https://youtu.be/zheQKmAT_a0?si=xoh5OInHkovn2bqG&t=1230 https://youtu.be/zheQKmAT_a0?si=xoh5OInHkovn2bqG&t=1230
- mihaaly 3y agoVery first thought at the very first picture: lots of negative corners next to the pots make cleaning the splills difficult.
- 83 3y agoIf you can pay that much for a stove surely your cleaning staff will take care of it :/
- oliwarner 3y ago> burners peak at 10 kW Elsewhere described as low current. That's 43A per burner, and 4 of them. Just two burners running is more than my 6 bed detached house's entire grid supply is fused for. Even if you smooth that out with massive super caps and local battery storage, I don't think my pans are going to last long doing that intensity. Sounds amazing. Too amazing.
