Pros
- Hot Espresso Without a Plug: The Nano 2 heats its 85 ml tank in as little as 159 seconds and brews at up to 21 bar from a 54Wh battery that recharges over 45W USB-C in about 100 minutes.
- Grounds or Capsules: Every Nano takes fresh ground coffee or Nespresso Original Line-compatible capsules, and the 740 g Nano 2 packs into a 71 mm-wide cylinder.
- Reviewed Where It Counts: James Hoffmann has reviewed the Nano, and the original model holds 4.2 stars across 5,733 Amazon ratings.
Cons
- Heating water from cold is the battery's biggest job — the original Nano manages up to five brews from room-temperature water — so topping up with hot water from a kettle or flask stretches every charge on longer trips.
- Defect claims begin with the brand's troubleshooting videos and a short clip of the issue, and change-of-mind returns within 30 days travel at your cost, so keep the box and accessories until your first few shots are pulled.
The Verdict
What sets OutIn apart is genuine hot espresso in a bottle-sized machine that needs no outlet: OutIn Inc. of Denver launched the Nano in January 2023 and has since built a small, focused range: the Nano, the new Nano 2 released on 16 September 2026, the IP67-rated Mino, the Fino electric grinder, the Claro scale and travel gift sets. The Nano 2 heats its own 85 ml of water in as little as 159 seconds with a 120W heater, brews at up to 21 bar, runs on a 54Wh battery that recharges over 45W USB-C in about 100 minutes, and takes either ground coffee or Nespresso Original Line-compatible capsules. The original Nano holds 4.2 stars across 5,733 Amazon ratings, and James Hoffmann's review put it in front of the specialty-coffee crowd. The Mino adds IP67 dust and water resistance for rougher trips, and the Fino grinder offers 28 settings in a 690 g body. Prices are clear: the Nano is $149.99, the Nano 2 $159.99 (regular $179.99), the Mino $199.99 and the Fino grinder $179.99 (was $199.99), with the Claro scale at $49.99 and the EVA protective case at $39.99. Orders process within 48 hours and ship free to the US and Canada over $39, from warehouses in the US, EU or China depending on stock, with a general delivery estimate of seven to ten working days. Duties, where they apply, are the buyer's responsibility, and P.O. boxes and APO addresses aren't served. The reservations are worth weighing. OutIn publishes no UL or ETL listing for these battery-powered heaters, the warranty is a 12-month limited one, and defect claims ask you to work through the instructional videos and send a clip first, though support also answers by phone on +1 (800) 889-5116. Change-of-mind returns within 30 days are at your cost. BBB rates OutIn F over three complaints it hasn't answered, and a consumer class action filed in Los Angeles challenges the original Nano's advertised battery capacity, while Trustpilot sits at 4.4 across 307 reviews. Made for travellers and trail-goers who won't give up proper espresso: hot water, 21 bar and ground coffee or capsules from a USB-C battery. Qualifying orders ship free to the US and Canada, and there are 30 days to return. Keep the packaging until you're settled, pre-heat water where you can and shop now.

About this review
How this was written, who paid for what, and how the verdict stays independent.
Is this outininc review sponsored?
No. outininc did not pay for this write-up, see it before publication, or have any say in the verdict. If we earn anything it is a commission after you buy, and it comes out of the merchant’s margin rather than your price.
How was the outininc assessed?
By using it and by checking the claims made about it against what it actually does. Where our time with something has been limited, the review says so rather than implying more testing than happened.
What else have you reviewed in Outdoors & Sports?
Everything in Outdoors & Sports sits in the review library, where you can filter by budget and sort by rating, price or how recently it landed.
Do you update reviews after publishing?
Yes — when a product changes, when a price moves for good, or when we get something wrong. Corrections are made on the piece itself with a note saying what changed.
