Our verdict

The OutIn Claro strikes a great balance between portability and smart features. With its compact round design, included travel case, and automatic coffee-to-water ratio calculation, it is an ideal companion for both home brewing and travel. While the round surface might be less stable for oversized carafes, its 0.1g precision and smart modes make it a highly capable tool.

Reasons to buy

  • Compact, round design with a rugged travel case for excellent portability.
  • Three smart brewing modes (Manual, Espresso, Pour-Over) with auto-tare.
  • High precision of 0.1g and a convenient physical switch to mute sounds.
  • Includes a heat-resistant silicone mat and offers up to 400 brewing cycles per charge.

Watch-outs

  • The round shape may be less stable for very large carafes or wide portafilters.
  • Auto-off triggers after 120 seconds of inactivity, which might feel short during prep.
  • Lacks Bluetooth or smart app connectivity for tracking brew profiles.

Smart Modes for Perfect Extraction

The OutIn Claro takes the math out of your morning routine. It features three dedicated brewing modes—Manual, Espresso, and Pour-Over—that automatically tare and calculate the essential coffee-to-water ratio. This ensures a consistent brew every time, whether you are pulling a quick shot or carefully pouring over your favorite single-origin beans.

Built for the Traveling Barista

With its round, corner-free design, this scale fits comfortably in one hand and slips easily into any bag. OutIn includes a waterproof and scratch-resistant protective case to keep it safe during transport. Keep in mind that due to international aviation regulations regarding its built-in battery, it must be carried in your hand luggage.

Practicality and Protection

A simple side switch lets you power the scale on or off and easily mute the audio feedback. The included food-grade silicone mat shields the scale from hot liquids and accidental splashes. Plus, with a battery life lasting up to 400 brewing cycles, you won't have to worry about frequent recharging.

Frequently asked questions

Is the OutIn Claro waterproof?

The scale is splash-resistant and comes with a protective silicone mat to guard against heat and spills, but it is not fully waterproof and should not be submerged.

Can I fit a standard portafilter on it?

Due to its compact, round footprint, wider or heavier double-spouted portafilters might be unstable on the scale. It is best suited for bottomless portafilters, cups, and smaller carafes.

How long does the battery last?

A full charge provides up to 400 brewing cycles, and the scale features a 120-second automatic shut-off to conserve power.
