Lepresso Portable 2-in-1 Espresso Maker
LePresso Portable 2-in-1 Espresso Maker
Technical / Technician-Oriented Description
1. Product Overview
The LePresso Portable 2-in-1 Espresso Maker is a battery-powered portable espresso machine designed for mobile and off-grid use. It supports dual brewing modes, allowing operation with ground coffee or Nespresso-compatible capsules, combining compact mechanical design with a high-pressure extraction system.
2. Electrical & Power System
Input Voltage: 9 V DC
Input Current: 2 A
Rated Power: 95 W
Battery Configuration:
3 × rechargeable lithium-ion cells
Capacity: 2500 mAh per cell (total ~7500 mAh)
Charging Interface: DC / USB-C charging port
Charging Time: Approx. 2.5 hours
Technician Notes:
Battery performance directly affects heating efficiency and brew time.
Battery capacity will degrade over repeated charge cycles.
Charging port and internal wiring should be inspected for looseness or oxidation during service.
3. Pump & Pressure System
Maximum Pump Pressure: 20 bar
Pump Type: Compact high-pressure electric pump
Function:
Forces heated water through coffee grounds or capsule for espresso extraction
Capable of generating sufficient pressure for crema formation
Water Path:
Water tank → pump → brew chamber → outlet nozzle
Service Notes:
Pressure loss typically indicates worn seals, clogged filter, or pump degradation.
Fine coffee grind may cause flow restriction in portable systems.
4. Heating & Thermal System
Heating Element: Integrated electric heating unit
Thermal Control:
Preset temperature control (non-PID)
Optimized for energy efficiency and portability
Brew Time:
Approx. 3–4 minutes from cold water to completed extraction
Technician Notes:
Heating performance depends on battery charge level.
Thermal cutoff protection prevents overheating during extended use.
5. Water Tank & Materials
Water Tank Capacity: Approx. 65 mL (single-shot volume)
Water Tank Material: SUS316 stainless steel (food-grade, corrosion-resistant)
Housing Material: High-impact ABS plastic with stainless steel components
Service Notes:
SUS316 minimizes corrosion and taste contamination.
Regular cleaning prevents scale buildup and flow restriction.
6. Brewing Compatibility
Supported Coffee Types:
Ground espresso coffee (recommended fine-medium grind)
Nespresso-style capsules (via adapter)
Brew Chamber: Interchangeable basket system for capsule or ground coffee use
Technician Notes:
Ensure correct adapter installation to avoid pressure leakage.
Inspect basket seals for wear or deformation.
7. User Interface & Operation
Controls:
Single-button operation
Indicators:
LED status indicators for power, heating, and brewing cycle
Operation Sequence:
Fill water tank
Insert capsule or ground coffee basket
Press power/brew button
Automatic heating and extraction cycle
Espresso dispensed into cup
8. Mechanical & Portability Design
Form Factor: Compact cylindrical portable design
Weight: Lightweight for travel and outdoor use
Mounting: Handheld or tabletop operation
Vibration Control: Internal damping to minimize pump vibration
Technician Notes:
Inspect housing for cracks caused by drops or transport damage.
Ensure all threaded connections remain tight after repeated use.
9. Maintenance & Service Considerations
Clean water tank and brew chamber after each use
Periodic descaling depending on water hardness
Inspect pump seals, O-rings, and internal hoses
Check battery health and charging circuit
Verify heating element operation if brew time increases abnormally
