The Renvaryn take
A clever answer to bad coffee on the move.
The Nano combines its own water heater, rechargeable battery and pressure pump in one compact brewer. That makes it unusually convenient in a car, hotel room or at work—provided what you want is a small espresso-style drink, not a full mug of coffee.
Our status: We have researched the Nano but have not yet tested it hands-on. Performance figures marked with an asterisk are OutIn laboratory claims and may vary in real use.
Who it is for
Best for espresso drinkers who spend time away from a kitchen.
Office workers
A compact option for desks and shared kitchens without space for a countertop machine.
Travellers
Made for hotel rooms, camping and day trips where a kettle or espresso machine is not guaranteed.
Product image: OutInHow it works
Four steps. No kettle required.
- 1Add coffee
Use compatible capsules or the supplied basket for ground coffee.
- 2Add water
Fill with hot or cold water, up to the stated 80 ml maximum.
- 3Secure the brewer
Screw the portafilter on firmly before starting the machine.
- 4Press and brew
Cold water is heated automatically; hot water can be extracted without the heating cycle.
The decision
Choose the Nano if…
- You regularly buy coffee while travelling or driving.
- You want one device that heats water and extracts.
- You value capsule convenience but still want a grounds option.
- A compact espresso is enough for your usual drink.
Look elsewhere if…
- You mainly drink large filter coffees or milk-based drinks.
- You need several cold-water brews back-to-back.
- You do not want to rinse small parts after using grounds.
- You already travel with hot water and prefer a simple manual brewer.
What matters in practice
The headline specs need context.
Cold water costs charge.
OutIn claims up to five brews from 50 ml room-temperature water, versus 200+ extractions if you supply hot water. Both figures are laboratory results.
Think espresso, not travel mug.
The tank holds up to 80 ml, while OutIn’s core battery test uses 50 ml. It is designed for concentrated drinks rather than large coffees.
Check your power adapter.
OutIn recommends a 5V/3A USB charger and notes that a low-power 5W adapter will not charge the machine properly.
Capsules are the easier route.
Pods minimise loose grounds. Using freshly ground coffee offers more control but means emptying and rinsing the small filter basket.
Quick comparison
Where the Nano fits.
It trades countertop capacity for portability and solves the hot-water problem that most manual travel brewers leave to you.

Before you buy
Four checks that prevent the wrong purchase.
Confirm the current total
Price, availability, delivery time and any import costs are controlled by the retailer and can change.
Choose your coffee method
Compatible capsules are quickest; ground coffee needs the right grind and firmer clean-up.
Plan for power
For frequent cold-water brewing, charge ahead or use an appropriate vehicle/USB charging setup.
Check travel rules
OutIn says the Nano should travel in carry-on luggage and must not be used during a flight. Always check your airline.
