Fresh Coffee Beyond The Kitchen

Bring a compact coffee setup to the places where a countertop machine simply does not make sense.

The 3-in-1 Portable Electric Espresso Maker combines a rechargeable brewing system, integrated water heating, and support for ground coffee plus two capsule sizes in one travel-ready design.

Add cold water and let the machine heat it before extraction, or use preheated water when you want a faster cup. Its integrated drinking cup keeps the entire setup compact for road trips, workdays, camping, hotel stays, and everyday travel.

This is designed for small, freshly prepared coffee servings on the go, not large multi-cup brewing.

Three Ways To Brew

Choose the coffee format that suits the day.

The modular brewing system includes dedicated configurations for:

  • Ground coffee
  • Small-format capsules
  • Large-format capsules

The upgraded ground-coffee holder accommodates approximately 8 g of coffee, providing more room than the earlier 4 g configuration shown in the supplier comparison.

Each adapter installs beneath the main unit, allowing the same compact machine to move between different brewing formats without requiring separate coffee makers.

For travel, capsules can provide a cleaner, lower-mess setup. At home or at the office, the ground-coffee holder gives you more control over the coffee you use.

Heat The Water Or Start With It Hot

Double-press the power button to begin the heating cycle. The machine heats water to approximately 92°C, with the manual specifying about 5 minutes for heating under its rated operating conditions. Once heated, the machine automatically proceeds into extraction.

Already have hot water available?

Add the hot water directly and use the extraction function without waiting for a full heating cycle. This is especially practical at the office, in a hotel, or anywhere a kettle is already nearby.

Extraction itself takes approximately 60 to 70 seconds, depending on the operating sequence referenced in the manual.

The manual specifically recommends hot water when aiming for a richer extraction. 

Compact By Design

This machine is built around portability rather than high-volume brewing.

The main unit measures approximately 83.5 × 83.5 × 245.5 mm, while the included drinking cup has a stated 120 mL capacity. The upgraded supplier specification indicates a water reservoir capacity of up to approximately 70 mL.

That makes it best suited to espresso-style or other small coffee servings prepared one cup at a time.

If you normally drink large mugs of coffee or regularly prepare drinks for several people in succession, a full-size coffee machine will be more suitable.

If you value a compact machine that can travel with you, the smaller format is the point.

The manual verifies the 83.5 × 83.5 × 245.5 mm product size and 120 mL cup capacity. 

Rechargeable For Life Away From The Countertop

Inside the portable body are three 2500 mAh 18650 battery cells, powering both extraction and the built-in heating system.

Charging is handled through the integrated USB-C port at a rated 5V/2A input.

Because heating water consumes considerably more energy than extraction alone, the practical number of cups per charge will vary depending on water temperature and usage.

One important operating limitation:

The machine cannot be used while it is charging.

Allow it to recharge fully before brewing.

The manual specifies 5V/2A charging, three 2500mAh cells, and states that operation is unavailable during USB charging. 

Designed To Come Apart For Cleaning

The cup and removable brewing components separate from the powered body to simplify routine cleanup after use.

Remove and rinse the appropriate coffee holder and drinking cup, then allow the components to dry before reassembly.

The powered host section contains the battery and charging electronics and must not be washed or immersed in water.

The manual specifically instructs users to clean the machine after use, keep it dry, and not wash the host portion. 

Know What A Portable Brewer Is Designed To Do

This product prioritizes portability, flexible coffee formats, and independent heating.

It is not intended to reproduce the volume, speed, or extraction characteristics of a full-size countertop espresso system.

Best For:

  • A personal coffee at work
  • Coffee during road trips
  • Truck or van use while parked
  • Camping and outdoor setups
  • Hotel stays
  • Small espresso-style servings

Consider Another Machine If:

  • You normally prepare full mugs in a single cycle
  • You regularly brew for several people
  • You require continuous brewing while connected to power
  • You expect commercial espresso-machine extraction and crema

Setting those expectations clearly makes this product much easier to enjoy for what it is designed to do.

Frequently asked questions

Does it heat the water itself?

Yes. The built-in heating system can heat cold water to approximately 92°C. The manual specifies an approximate five-minute heating cycle under rated conditions.

Can I use hot water instead?

Yes. Preheated water can be added directly, allowing you to skip the full cold-water heating cycle and proceed to extraction. The manual recommends hot water when seeking a richer extraction. 

What types of coffee can I use?

The machine includes separate configurations for ground coffee, small-format capsules, and large-format capsules. Because capsule dimensions vary between manufacturers, compare your capsule with the supplied holder before use.

How much coffee does it make?

This is a compact single-serving machine. The upgraded supplier specification indicates a water reservoir of up to approximately 70 mL, while the included drinking cup is rated at 120 mL. It is intended for small espresso-style servings rather than filling a large mug in one cycle.

Is it the same as a full-size espresso machine?

No. Its advantages are portability and independent heating. Customers should expect a practical travel coffee maker, not the speed, capacity, crema consistency, or continuous output of a full-size countertop espresso system. This expectation aligns with recurring purchaser feedback, where portability and convenience were praised while serving size and countertop-level performance were the most common limitations. 

Can I use the machine while it is charging?

No. The instruction manual states that the unit cannot operate during USB charging and must be charged before use. 

Can the whole machine be washed?

No. The removable brewing components and cup can be cleaned separately, but the powered host section must not be immersed or washed. Clean the unit after use and keep it dry. 

What happens if I try to heat it without water?

Do not operate the heating function with an empty water reservoir. The machine includes anti-dry protection, but the manual still specifically warns against heating the device without water.
