Rechargeable tDCS Device with Dual Outputs & 4 Current Levels

MEL128B Rechargeable tDCS Device – Adjustable Transcranial Stimulation Technology

The Mewloria MEL128B is a compact transcranial direct current stimulation (tDCS) device featuring a single-channel, dual-output configuration.

Engineered with adjustable constant-current output, intuitive controls, and a rechargeable power system, the MEL128B provides a versatile hardware platform for electrotherapy product development and distribution.

Its streamlined design combines straightforward operation with practical functions such as adjustable session durations, gradual current transitions, and electrode connection monitoring.

For distributors, private-label brands, and OEM/ODM partners, the MEL128B offers an established product configuration that can be evaluated for different market and branding requirements.

Key Features & Benefits

1. Single-Channel Dual-Output System

The MEL128B uses one stimulation channel connected to two output ports.

This configuration enables a coordinated output through a connected electrode pair without requiring two independently controlled channels.

Highlights:

• Single-channel stimulation architecture
• Two electrode output connections
• Constant-current output design
• Straightforward electrode connection setup

2. Four Adjustable Current Levels

Customize the device’s output using four selectable current settings:

• Level 1: 0.5 mA
• Level 2: 1.0 mA
• Level 3: 1.5 mA
• Level 4: 2.0 mA

The specified output tolerance is ±0.2 mA.

Physical adjustment buttons allow the selected output level to be changed within the supported range.

3. Gradual Current Ramp-Up and Ramp-Down

The device incorporates an approximately 30-second current transition when initiating or pausing stimulation.

Rather than switching abruptly to the selected output level, the current gradually transitions between the low-level detection current and the configured stimulation level.

This controlled-output design is intended to reduce abrupt current changes during operation.

4. Three Adjustable Timer Settings

Choose from three preset session durations:

• 10 Minutes
• 20 Minutes (Default)
• 30 Minutes

The built-in timer offers convenient session-duration control without requiring an external application or additional controller.

5. Built-In Load Detection

The MEL128B includes an electrode-load detection function.

When the output load is disconnected, the device operates with a nominal 0.1 mA detection current to monitor the connection.

This function is designed to support connection monitoring during operation and provides an additional level of output control.

6. Convenient Controls and Display

The device features a clear display and dedicated physical controls.

Functions include:

• Power On/Off
• Stimulation Start/Pause
• Output Intensity Adjustment
• Session Timer Selection
• Button Lock
• Battery Level Indicator

The white display backlight automatically turns off after approximately 10 seconds of inactivity.

The device also supports automatic shutdown after approximately two minutes without output or user operation.

7. Rechargeable and Portable Design

Powered by a built-in 320 mAh rechargeable lithium battery, the MEL128B eliminates the need for disposable batteries.

• USB Type-C Charging Interface
• Approximately 2-Hour Charging Time
• Approximately 4-Hour Operating Time per Full Charge
• Compact Handheld Housing
• Convenient for Transport and Storage

Actual operating time may vary with usage conditions.
