Ningbo Tongxin Technology manufactures the CM1001B-PLUS rechargeable coffee maker for international importers, distributors, retailers and private-label brands. Understanding its portable coffee maker internal components helps buyers evaluate heating performance, pump operation, battery capacity, coffee compatibility and product reliability before starting an OEM project.

In this teardown, we divide the CM1001B-PLUS into four principal systems: the heating module, water-pump module, battery and control system, and 3-in-1 extraction module.

These systems work together to heat water and extract coffee inside a compact, cordless product designed for travel, driving, camping, offices and outdoor use.

Portable Coffee Maker Internal Components Overview

The CM1001B-PLUS contains several connected mechanical, electrical and water-flow components.

Buyers can also explore our portable coffee maker range to compare the CM1001B-PLUS with other available configurations.

Its principal systems include:

Heating module
Water-pump module
Rechargeable battery pack
Control board and temperature protection
Water tank and internal water path
3-in-1 coffee extraction system
Product housing and sealing components

Each system affects the complete product.

For example, increasing heating power may reduce heating time, but it can also increase battery consumption, temperature rise and electrical loading. Increasing pump pressure does not automatically improve the coffee if the capsule holder, coffee basket or water-flow path is unsuitable.

A reliable self-heating portable coffee maker therefore requires the heating, pumping, battery and extraction systems to be designed and evaluated together.

Heating Module: 12V and 100W

The CM1001B-PLUS uses a 12V/100W water-heating module.

Under typical test conditions, the system can heat approximately 50ml of room-temperature water to about 85°C in approximately five to six minutes. Actual heating time can vary according to:

Initial water temperature
Water volume
Ambient temperature
Battery charge level
Battery condition
Heat loss through the product
Target temperature setting

The maximum water-tank capacity is approximately 100ml. However, the heating time and number of cups per charge depend on the actual amount of water heated for each serving.

Thick-Film Heating Technology

The heating module uses thick-film heating technology. The heating element is integrated with a heat-transfer surface to warm the water inside the machine.

The main advantages include:

Relatively even heat distribution
Compact construction
Suitable integration within a portable product
Fast thermal response
Stable heating performance
Good reliability under normal operating conditions
Reduced need for a large conventional heating assembly

The compact structure is important because a portable coffee maker has limited internal space for the battery, pump, water path, electronics and insulation.

The main disadvantage is cost. A suitable thick-film heating module is generally more expensive than a simple resistance-wire heating solution.

The heating surface must also remain sufficiently flat to provide stable heat transfer. Its structure, water outlet and water-tank geometry can affect the amount of water remaining after extraction.

Customizable Water Temperature

The target water temperature can be adjusted for an OEM project, subject to technical evaluation.

Changing the temperature may affect:

Heating time
Battery consumption
Number of cups per charge
Coffee extraction
Housing temperature
Component life
Safety protection
Applicable product testing

For projects requiring a customized heating temperature, the expected MOQ is generally 2,000 units. Final feasibility must be evaluated according to the required temperature and product configuration.

Temperature Detection and Protection

A portable coffee maker with an internal heating system needs both temperature control and abnormal-temperature protection.

The CM1001B-PLUS uses an approximately 85°C water-temperature detection setting for normal heating operation. It also includes an approximately 120°C temperature-protection function to help respond to abnormal overheating conditions.

These two functions serve different purposes:

The water-temperature sensor controls the normal heating target.
The higher-temperature protection provides an additional safety response if abnormal heating occurs.

The control system must also coordinate heating, pump operation, indicator lights and battery condition.

If a buyer requests a different water temperature, heating power, battery or control method, the temperature-control and protection settings must be reviewed as part of the complete system.

Rechargeable Battery System

The CM1001B-PLUS contains a 10.8V/2,600mAh rechargeable lithium-ion battery pack with a rated energy of approximately 28.08Wh.

The standard battery pack contains three cells connected in series. The series connection increases the operating voltage while maintaining the cell capacity at 2,600mAh.

The battery supplies energy to:

The heating module
Water pump
Control board
Indicator lights
Temperature-monitoring system

Heating cold water consumes substantially more battery energy than extracting coffee with prepared hot water.

When cold water is used, a fully charged machine can typically prepare approximately three to five cups, depending on water volume, starting temperature, ambient conditions and battery condition.

When prepared hot water is added, the heating element does not need to complete a full heating cycle. Battery consumption is therefore substantially lower because the machine mainly powers the pump and control system.

USB-C Charging Input

The standard charging input is 5V/2A through a USB-C connection.

A power source providing only 5V/1A may charge the machine more slowly. For vehicle use, a suitable cigarette-lighter adapter that provides a stable 5V/2A USB output can be evaluated.

The charging source should meet the confirmed input requirements. Using an unsuitable adapter or cable may increase charging time or result in unstable charging.

Water-Pump Module: 12V, 5W and 20 Bar

The CM1001B-PLUS uses a 12V/5W high-pressure pump with a rated pressure of up to 20 bar.

The pump moves heated water from the water tank through the internal water path and into the selected extraction holder.

Advantages of the High-Pressure Pump

The pump provides several benefits:

Suitable pressure for espresso-style extraction
Compact size for portable-product integration
Compatibility with capsule and ground-coffee holders
Controlled water delivery
Cordless operation through the battery system
Ability to work with a relatively small water volume
Stronger extraction than low-pressure portable brewing methods

The high-pressure system helps water pass through the coffee capsule or compressed ground coffee.

However, rated pump pressure should not be treated as the only measure of coffee quality. Extraction also depends on:

Coffee particle size
Coffee quantity
Coffee compression
Capsule construction
Holder design
Water temperature
Water-flow resistance
Sealing
Extraction time

Pump Limitations

A compact high-pressure pump also has limitations:

It produces operating noise and vibration.
Performance can be affected by air inside the water path.
Scale accumulation can affect water flow.
Incorrect assembly or damaged seals may cause leakage.
Very fine coffee may create excessive flow resistance.
Uneven coffee loading may produce inconsistent extraction.
Pump life depends on operating conditions and cleaning.

The water-flow path, seals and extraction holder must be matched to the pump. Simply using a higher-pressure pump does not guarantee better coffee.

Internal Water Path and Sealing

Water travels from the tank through the heating and pumping system before entering the coffee holder.

The internal water path includes:

Water tank
Heating surface
Water inlet
Pump
Tubes or connecting channels
Seals
Outlet connection
Coffee holder

Sealing is especially important because the machine combines hot water, high pressure, electrical components and a rechargeable battery inside a compact housing.

Quality-control checks should therefore cover:

Water leakage
Tube connections
Seal installation
Pump operation
Water flow
Heating operation
Extraction-holder installation

A small quantity of water may remain in the heating area after extraction because of the flat heating surface and the position of the water outlet. This is a structural characteristic and does not necessarily indicate pump failure.

The remaining water should be emptied after use, and the machine should be cleaned according to the user instructions.

Three-in-One Extraction Module

The CM1001B-PLUS uses interchangeable holders to support three standard coffee formats:

Nespresso® Original-style capsules
Dolce Gusto®-style capsules
Ground coffee

The appropriate holder is installed before extraction.

This interchangeable design allows distributors and private-label brands to offer several brewing options through one machine rather than selling a separate product for every coffee format.

Nespresso Original-Style Capsule Holder

The Nespresso Original-style capsule holder positions the capsule and allows pressurized hot water to pass through it during extraction.

Important evaluation points include:

Capsule dimensions
Capsule material
Capsule positioning
Piercing performance
Holder locking
Water sealing
Used-capsule removal
Coffee flow

Capsules from different brands may vary slightly in material, shape, sealing film and internal coffee density. Sample testing with the customer’s intended capsules is recommended before mass production.

Dolce Gusto-Style Capsule Holder

The Dolce Gusto-style holder accommodates the larger capsule format and has a different internal structure from the Nespresso-style holder.

Evaluation should cover:

Capsule fit
Piercing position
Holder installation
Sealing
Water flow
Beverage volume
Cleaning after use

Different beverages may require different water volumes. The machine’s 100ml water tank should therefore be considered when buyers select compatible capsule beverages.

Ground-Coffee Holder

The CM1001B-PLUS ground-coffee holder uses an approximately 51mm coffee basket with a maximum coffee capacity of approximately 15g.

The larger basket provides flexibility in coffee quantity compared with smaller portable coffee holders.

Ground-coffee extraction depends on:

Coffee-particle size
Coffee quantity
Distribution
Compression
Filter configuration
Water temperature
Flow resistance
Cleaning

Coffee that is too fine or compressed too tightly may restrict water flow. Coffee that is too coarse or loosely filled may produce faster and weaker extraction.

The standard configuration can operate without a disposable paper filter. A stainless-steel filter solution may also be evaluated according to the project requirements and target cost.

Evaluating Other Coffee Formats

Additional holders or adapters for other coffee formats may be evaluated as customized projects.

However, adding another format is not simply a matter of changing the exterior shape of the holder. Engineering evaluation may be required for:

Capsule dimensions
Piercing method
Sealing surface
Water inlet
Flow resistance
Extraction pressure
Beverage volume
Holder locking
Cleaning
Intellectual-property considerations

Compatibility should only be confirmed after testing with the actual capsule, pod or coffee product intended for the target market.

Formats that are not included in the standard 3-in-1 configuration should not be advertised as compatible until their holders and extraction performance have been verified.

How the Four Main Systems Work Together

The operating process can be summarized as follows:

The user adds water to the tank.
The appropriate coffee holder is installed.
The battery supplies power to the control and heating systems.
The heating module raises the water to the target temperature.
The temperature sensor signals when heating is complete.
The pump moves the heated water through the extraction holder.
Coffee flows into the cup below the machine.
The user removes and cleans the holder after extraction.

When prepared hot water is used, the user can activate the hot-water extraction mode without completing a full cold-water heating cycle.

The heating module, battery, pump and coffee holder must all operate correctly for stable extraction.

Advantages of the CM1001B-PLUS Structure

The internal design provides several practical advantages:

Built-in cold-water heating
Rechargeable cordless operation
Three coffee-format options
Up to 20-bar pump pressure
Approximately 15g ground-coffee capacity
Compact integrated structure
USB-C charging input
Hot-water extraction mode
Suitable for travel and outdoor use
OEM and private-label customization

For distributors and brands, the 3-in-1 configuration can support a wider consumer group without requiring three separate portable coffee makers.

Engineering Trade-Offs

Portable coffee maker development involves several engineering trade-offs.

Heating speed and battery life

Higher heating power may reduce heating time but increase current demand and battery consumption.

Water capacity and product size

A larger water tank provides more beverage volume but increases the size and weight of the machine.

Pump pressure and flow resistance

Higher pressure must be matched with suitable coffee holders, seals and water paths.

Battery capacity and portability

A larger battery may increase the number of cups per charge but also increases cost, weight and internal space requirements.

Coffee capacity and extraction consistency

A larger ground-coffee basket provides flexibility, but users must still control grind size, quantity and compression.

Product evaluation should therefore consider the complete system rather than one specification alone.
