Review: Perfect for Cappuccinos and Lattes on the Go! - I love this thing, just used it with my OutIn Nano to make a delicious cappuccino in my hotel room. As a bit of a coffee addict, traveling sucks sometimes. Sure I can get a cappuccino at a coffee shop, but not before I wake up, get showered, get dressed, and drag my tired self out the door. With this frother, my OutIn Nano, some shelf stable milk, a few Nespresso pods, and a cup I can whip up a tasty cappuccino or latte before I try to get my day started. So let’s talk about how it works. It’s a handheld frother. You put some milk in a cup and turn this thing on and it froths the milk. But holy sweet mother of whatever savior you believe in, this thing is POWERFUL! I wasn’t expecting it and made a little bit of a mess the first time, but now I know better and the second time was perfection! This doesn’t heat the milk, so if you want hot milk you’ll have to be staying somewhere with a microwave, but for me the OutIn Nano makes the espresso hot enough that it works out. The two screens let you choose your foam texture, which is nice, the finer one is more like a micro foam, while the coarser one is closer to what you’ll get with a more traditional, whisky type frother. The travel cover is a brilliant addition, keeping the extra screen within easy reach and protecting the whole setup. I didn’t worry once about things getting damaged in my backpack. Definitely worth the $50 price tag, and makes me seriously consider getting their carafe-based model for at home, even though I’m really happy with my Instant Pot brand frother. Subliminal makes a quality product for sure!
Review: Mixes well and no scratches on cup - Product is excellent! I bought it because I don’t like my cups getting scraped with the stainless milk frothers. I am not creating fancy lattes but rather mix protein powders in my coffee. Mixes them perfectly! I’ll bet it would make beautiful foam designs too. Very powerful. Haven’t had it long enough to opine on battery issues discussed in other reviews. Hopefully the company gets that figured out before I have to replace.

## Features

- High-Performance Power: Cafe-quality microfoamed milk is now possible with a handheld tool! No need for a costly espresso machine or to settle for unsatisfactory dry froth from ordinary whisk-style frothers. Make barista-style cappuccinos and practice latte art every day with the NanoFoamer Lithium milk foamer, powered by a lithium-ion battery. The Lithium is our USB-C rechargeable version.
- Advanced Features: Our Black Lithium Nanofoamer provides 300% more power than conventional handheld milk frothers for unbeatable whisking capabilities. The microfoamer includes a digital on/off switch, replaceable impeller, click-on NanoScreens, stainless steel motor cover, a more stable heavy-duty stainless steel shaft, and new battery housing to reduce vibrations, IP4 waterproofing, premium internal components, and overall better design and engineering.
- Convenient Battery Maintenance: The Lithium NanoFoamer comes fitted with a USB-C rechargeable lithium-ion battery, making recharging a breeze. The battery level indicator takes the guesswork out of the equation, keeping you updated about power status. The device's dual-speed digital switch lets you control speed, making adjustments effortlessly.
- Patented NanoScreen Technology: The unique patented impeller and NanoScreen technology create better-tasting, premium, smooth milk. Not steaming milk? No problem! Easily pop off the device's nano screen and use the device for mixing and stirring drinks, protein powders, matcha, and more. Perfect for those seeking versatility in their kitchen gadgets, our Nanofoamer is a great gift for coffee lovers and is an ideal addition to any wedding registry.
- User-Friendly & Easy to Clean: To use, simply churn warm milk for about 30 seconds, then pour your perfectly microfoamed milk over an espresso or coffee drink of your choice. This coffee milk foamer is waterproof to level IP4, which means you can freely rinse it under running water after each use. Store your NanoFoamer on the adhesive wall-mount or put the protective hood on and keep it in a drawer for easy storage.

## Questions & Answers

**Q: Does this work with rechargeable batteries or just alkaline batteries?**
A: It does work with rechargeables, and we recommend using rechargeables because it is quite power-hungry.

**Q: Can this be used to blend bullet proof (MCT oil) coffee?**
A: It is powerful enough, but you might want to remove the NanoScreen when doing that to get better mixing if you're not looking for microfoaming capability.

**Q: Can you make cold foam with almond milk with this ?**
A: Yes, it works well if you choose a "Barista Edition" milk alternative because they are designed to foam up. It won't work with homemade almond milk for instance as there is nothing in it to create the surface tension you need for foam.

The final textures with cold milk and milk alternatives can feel slightly different from hot milk, but you still get a nice foam.

**Q: Is the lithium cell USER replaceable? Or is this a non-green product you have to throw away the whole thing when it stops holding a good charge?**
A: The latest versions (Starting August 2023)  have been updated to include a changeable battery.

### ⭐⭐⭐⭐⭐ Best Foamer on the Market!
*by T***E on May 5, 2025*

If you love a high quality and sleek design frothed then this is perfect for you. Not only does it have 2 different speed settings it also comes with 2 different nano screeds so that you can customize the amount of foam. Also very easy to clean and comes with a wall mount. It works perfectly with my non-diary milk which usually takes so long to froth but with the NanoFoamer this is quick and gets the job done.
