How to Use Your OneStow
Three ways to load coffee, two ways to brew. Here's everything, step by step.
1. Load your coffee
Small capsules
1. Place the capsule in the small-capsule adapter.
2. Close the adapter over the capsule.
3. Insert the adapter into the brewing chamber.
4. Screw the chamber onto the cup.
Ground coffee
1. Fill the basket with fine, espresso-grind coffee.
2. Press the lid onto the basket.
3. Seat the basket in its holder.
4. Insert the holder into the brewing chamber.
5. Screw the chamber onto the cup.
Large capsules
1. Place the large capsule in the large-capsule holder.
2. Insert the holder into the brewing chamber.
3. Screw the chamber onto the cup.
4. Attach the cup and chamber to the machine.
2. Add water
Remove the top lid and pour up to 60 ml (2 fl oz) of water into the tank, then put the lid back on. Use cold water if you want the machine to heat it, or hot water to brew immediately.
3. Choose your mode

Charging
Plug the included USB-C cable into a wall adapter, power bank or car USB port. A full charge takes about 3–4 hours and gives up to ~4 heated brews or ~50 brews with pre-heated water (manufacturer figures).
Cleaning
After brewing, run one cycle with fresh water and no coffee to flush the inside. Unscrew the chamber, then rinse the adapters, basket and cup under the tap and let them dry.
Tips for a better shot
- ✓Use fine, espresso-grind coffee — coarse grinds brew weak and fast.
- ✓Don't overfill the tank: 60 ml is one full shot.
- ✓Charge fully before a trip; heating cold water uses the most battery.
- ✓For a stronger cup in cold weather, start with warm water.
