Rapid Heating

The CERA+ portable espresso machine utilizes ceramic heating technology to heat water fast. It takes only 3-4 minutes to reach the optimal espresso brewing temperature of 96°C/205°F. Before first use, please fully charge the machine with a charger (output ≥ 2A) and a Type-C charging cable for at least 3.5 hours. The 20 bar pressure extraction then efficiently brews the coffee grounds or capsule to produce espresso complete with a rich crema layer. This speedy heating system means you get barista-quality coffee quickly.

Three Brewing Modes

The CERA+ PCM03 offers three brewing modes: cold brew, hot water brew, and cold water heating then brew. You can choose different brewing methods according to your preferences and needs. The cold brew mode is suitable for users who prefer a refreshing taste, the hot water brew mode allows you to enjoy a cup of hot coffee faster, and the cold water heating then brew mode provides you with more flexibility.

Intelligent LED Indicator

The CERA+ PCM03 is equipped with an intelligent LED indicator that not only displays the battery level but also the water temperature status. You can understand the working status of the machine through the color and flashing mode of the indicator light, such as heating, heating completed, or low battery.

Boil-Dry Protection

To ensure safety, the CERA+ PCM03 has a boil-dry protection function. When the machine detects that there is no water inside, it will automatically stop heating to prevent damage to the machine due to dry burning.

Heat Insulation Design

The CERA+ PCM03 adopts a heat insulation design to ensure that no heat damage is caused during the brewing process. You can safely hold the machine without burning yourself.

Portable Power

The built-in 7500mAh rechargeable lithium-ion battery supports making multiple cups of espresso on one full charge. You can brew 4-5 shots of espresso by adding cold water or make over 200 cups by adding hot water instead.

Charging it fully takes around 3.5 hours. The battery life enables you to enjoy freshly brewed espresso anywhere - at your campsite, hotel, office, or even in your car.

Safety Features

The portable coffee maker contains useful safety features like boil-dry protection and a heat-insulated exterior. Sensors prevent the machine from heating without water. The outside remains cool to the touch while brewing hot coffee inside.

An LED interface indicates when the machine is heating up and clearly displays the battery level so you know when to recharge. These thoughtful elements enhance safe usage.


Cleaning the CERA+ is quick and easy. After brewing, simply remove the adapter and filter basket. All parts are detachable for rinsing under running water. A cleaning brush is included for scrubbing away residual coffee oils and grounds. Let components air dry fully before next use.

Who Should Buy This Portable Espresso Machine?

The CERA+ PCM03 is ideal for certain users:

  • Travelers who want freshly brewed espresso on the go
  • Campers and hikers seeking an off-grid espresso solution
  • Those with hectic lifestyles who need coffee anytime, anywhere

  • Anyone seeking an espresso maker for a dorm room, office, or small kitchen

Frequent travelers will love having real espresso from this battery-powered machine. The CERA+ allows campers and hikers to enjoy premium coffee while off the grid. Busy professionals can save time and money by brewing self-made espresso at the office. It also suits small home kitchens with limited counterspace.

Real Customer Reviews

Based on the user feedback provided in the given data, it’s evident that the CERA+ PCM03 Portable Mini Espresso Machine garners a mixed reception, with an average rating of 3.9 out of 5 stars.

In conclusion, while the CERA+ PCM03 excels in brewing quality espresso and offers notable convenience and portability, its user feedback profile indicates areas for improvement, particularly in the realms of pod adapter functionality, noise control, battery longevity, and customer support. Addressing these concerns could significantly enhance the user experience and bolster the product’s standing in the competitive portable espresso machine market.
