What owners say about the OutIn OTEM-01

Based on 219 owners sharing their experience in online comments

71%positive14%mixed15%negative

Owners love having espresso wherever they go, while uneven temperatures and inconsistent shot quality cause the most frustration.

What owners dislike

  • Shots can taste weak, bitter, or thin, with little crema, especially with capsules or lighter roasts.20
  • Owners report the pump or heater stops working after months of use, often after storage or a few hundred shots.15
  • Water from the built-in heater often brews too cool, so owners say preheating or using kettle water helps.12
  • Owners say getting a good shot takes trial and error with grind size, dose, and ratio before results are consistent.8
  • Using the built-in heater to heat cold water drains the battery quickly, sometimes after only three or four drinks.7
  • Some baskets, especially with capsules, produce little or no crema, and owners say the shots taste more like filter coffee.7
  • Heavy to carry once accessories are added, and owners say it takes up the space of a water bottle.5
  • Owners report water leaking or dripping from the seals or the portafilter connection during or after brewing.5
  • The better basket and tools that improve shot quality cost extra, about 40 pounds or euros on top of the machine.4
  • Capsules sometimes fail to extract or pierce properly, so the coffee comes out weak or not at all.3

Third-party reviews

What customers like about OutIn OTEM-01

  • A 20 bar pump gives the coffee enough pressure for a proper espresso.
  • It heats its own water, so you do not need a kettle.
  • It works with capsules as well as ground coffee.
  • Overheat protection and automatic shutdown make it safer to use.
  • At around 700 g it fits in a backpack.
  • The transparent reservoir lets you see how much water is left.

What customers don't like about OutIn OTEM-01

  • The 0.08 L water tank is very small.
  • At 90 W it is slow for large cups, so you need several runs.
  • It is designed for espresso, so it does not make a big mug of coffee in one go.
  • Around 700 g is heavy for ultralight hikers.
  • There is no display and no app to adjust the brew.

Verdict

A 20 bar pump is the main reason to look at the OutIn OTEM-01, a small espresso maker for people who brew away from home. It heats its own water, so there is no kettle to carry. Reviewers found the crema good and the flavour strong for a machine this size. It takes ground coffee or capsules, and it switches off on its own. The machine weighs around 700 g, so it slips into a backpack without much fuss. The trade-off is the small tank, which holds only 0.08 L. The 90 W power is modest, so a big mug takes several runs. It suits a hiker, camper or van owner who wants one good espresso on the move and does not need much more.
