Perfect and stylish

I’m really happy with this electric kettle! It heats water quickly and is very easy to use. The glass pitcher makes it convenient to see the water level, and the temperature controls are great for getting the water exactly how I want it. I also love the modern design—it looks clean and stylish on my kitchen counter. The handle feels comfortable and sturdy, and the keep-warm feature is especially convenient. Overall, it’s practical, well-designed, and something I use every day. Definitely recommend!

Product Details
  • Game Changer for Parents:
No more waiting for a bottle to warm! Simply pour water from the Grownsy instant warmer into your bottle, add the recommended amount of formula, and shake. That’s it. For formula feeding, it replaces the wait that comes with traditional bottle warmers. Always follow the mixing instructions on your formula packaging.
  • Accurate Temperature Control with Timer:
Set the temperature anywhere from 0–100°C/0–212°F. This instant hot water dispenser kettle uses a built-in semiconductor sensor and an external NTC temperature probe for consistent control. Set the temperature. Set the timer. Your water is ready when you need it—for formula, coffee, or tea.
  • Constant Warming:
This instant warm water heater keeps water warm all day and night, so you can prepare a bottle whenever your baby wakes. Bright LED indicators show when the kettle is heating, while boil-dry protection automatically shuts it off when the water runs out. Set your preferred temperature once, and warm water stays ready for the next feeding.
  • Boil Function as Electric Kettle:
Need boiling water fast? This fast boiling electric kettle quickly prepares hot water for tea, oatmeal, coffee, pasta, and more. The generous 1.2 L capacity holds enough water for the whole family. One kettle. More everyday possibilities.

FAQs on Grownsy Instant Warmer

It's a temperature-controlled water kettle that keeps safe water ready for mixing powdered formula. Instead of warming a finished bottle, you pour the selected water volume, add the exact formula amount, and mix according to the label. Grownsy combines a 1.2-liter glass tank, 0–100°C control, an LED display, and keep-warm operation for faster day and night preparation.

A traditional bottle warmer heats milk that is already in a container, while an instant hot water kettle prepares and holds water before formula is mixed. Our product's system replaces the wait for a kettle to boil and cool at every feed, letting you dispense or pour water at the chosen setting. It does not automatically measure powder, so label ratios still matter.

Keeping correctly prepared water ready removes the boil-and-wait step when your baby wakes. The 1.2-liter capacity supports multiple feeds, while the LED display and night light help you pour with less disruption. Grownsy speeds the water stage, but you must still measure water first, add the exact powder amount, and use prepared formula within safe time limits.

A soft light makes the display and water level easier to see without turning on bright room lighting or waking your household. This model pairs its LED temperature screen with a night light, so you can measure and pour more calmly. Keep the unit on a stable, dry counter and never trade visibility for skipping the final water and formula checks.

Good product but…

We enjoyed using this product at first. It got us through the first few months of life with a newborn. However, the lid of bottle warmer/kettle broke down and made it into the boiling water. Totally unsafe for our little one and all of us. Reached out, seller offered a replacement lid. Seller is not based in the US by the way. The replacement lid took about a month to arrive. The replacement is bigger than the original, and the quality was worse. It also rusted in less than two weeks. Now we see crystals in the water after using the kettle to boil water. Buy from this seller at a great risk to your health.

I use this every day making my baby’s formula

Heats up water very fast and I love how you can adjust the temp. Most I’ve tried have a few pre set temps so I love how much you can do with this one!!

Calentador de agua para biberones

Si o si tienes que usar agua destilada ya que si usas agua normal o de la pila empieza a despegarse el producto de abajo y se queda en el agua que le estás dando a tu bebé , mucho cuidado con eso
Por otro lado , el producto es muy bueno y te saca despegarse aprietos y tienes agua caliente a la mano

Good Temp Control Electric Kettle

I didn't buy this to warm baby bottles. But, this is an excellent electric kettle when temperature control is needed. I use it as a water bath to steep herbs, such as making a turmeric oil. And, it can be used the same way to make yogurt. The temperature control allows for long warming/steeping times at 105-110 so as not to kill off beneficial bacteria or enzymes.

Time saver for bottle making

I bought this as a means to boil water and then have water at-the-ready for making bottles of formula. This was for baby #3 who have all been formula fed and I wish I did this method from the start. Having water ready at the perfect temperature for your baby is a huge time (and sanity) saver when you have a hungry infant screaming, especially when they decide the 4oz wasn’t enough and are demanding more. Bottle warmers are inconsistent and take so much longer and has one purpose. This kettle is at-the-ready and has other uses beyond bottle making. Making it much more versatile of a product (++value). For the Americans, don’t be afraid of the metric controls, there’s a conversion chart on the kettle.

Great!

I absolutely like the size of this and the wide range of temperature settings. I have this on almost 24/7 (going on 4 months) and it still works great!

A Must Have!

We previously bought a baby bottle warmer, but quickly realized this instant warmer is so much better! It maintains a consistent temperature, allowing us to warm bottles much faster - especially helpful when the baby is hungry and needs it right away. Even when we’re not using it for the baby, we use it to keep water warm for ourselves. Definitely a must-have at home!

Helpful

Keeps water warm for formula. It's temperature is adjustable and even has the body temperature on a sticker! It was a reasonable price and doesn't take much space on my counter. Just took it right out of the box! No need to assemble.

Best thing ever.

This is the absolute best tea kettle. I bought it to use with a neti pot. Boil the water then get it down to usable temp; but i use it multiple times a day for everything else. Have had it about a year. Great for tea, instant coffee/ mushroom coffee, hot chocolate, soup, rehydrating dogs food. I keep it on round the clock. So i have hot water whenever i want it. I forgot to fill it once and it turned itself off. If you put cold water in it heats in less than a minute. Only flaw.... its centrigrade instead of fahrenheit!!

Fantastic electric kettle

I bought this kettle on Apr 14, 2021 - and it has held up so well in that time. I am only just now considering purchasing another one as ours is starting to make a bit of noise when used, but it otherwise does it's job perfectly. Size wise it will take up a bit of counter space, but if you make tea or hot cocoa or want to use it for formula, it's a perfect addition and I always have it on my countertop. Fantastic purchase and if I need another one, I'm going to rebuy this one!

So helpful

Game changer, so helpful. Formula is supposed to be made using water at a temp of 158, how the eff do you know that without using a thermometer? This things saves you the hassle of trying to figure it out.

Use it to warm water for my cats' food

I actually use this to warm water for adding to my cat's food. I could never get the temperature right trying to heat it in the microwave. It works great.

Worth it! Great product & customer service!

We’ve had this for about a year and use it to heat up the water for our baby’s formula. It boils very quickly and then will reduce the temp to the desired setting so it stays warm all day/night! Just need to wash kettle and refill the water. I’m blown away by the customer service! The glass kettle was accidentally knocked over and shattered recently and I emailed the company to see if I could purchase just the glass kettle since I still have the base, and they sent me an entire new kettle and base for free and it arrived just a couple days after I emailed them! I was more than willing to pay for another kettle because we loved it so much, but how awesome that they sent a whole new one to us. Very pleased and excited to use it again!

Overall good quality kettle

Love this kettle. Our baby likes to drink warm formula and this kettle boils water in minutes and keeps it warm at the specific temperature at all times. Huge time saver and makes life so much easier at night. Holds good amount of water that lasts us all day. Overall a good quality kettle with no issues so far.

3 years of constant use - still going strong!

I don’t normally write reviews, but this is such a good item I feel compelled to write one.
We’ve had ours for over 3 years, and it has been on constantly since we bought it (minus a few days/weeks when we are out of town, etc.). It still works great, holds temp great, boils water quickly. The LED display is showing some wear and tear, but again after daily use for 3 years I would expect this.
