Tonfarb A20 136GB Voice Recorder Pink

Portable Audio Capture

The Tonfarb A20 is a compact voice recorder that combines 8 GB of internal memory with a supplied 128 GB microSD card for 136 GB total capacity. It records in WAV or MP3 at selectable bit rates and offers voice-activated, timed and segment recording modes. A 1.44 inch display and one-click side switch let users start and save recordings instantly, while password protection secures stored files. The device weighs 100 g and measures 0.47 x 1.45 x 4 inches.

From Basic Dictation to Extended Sessions

This unit replaces simple memo recorders that only offer a few gigabytes of storage and lack voice activation or file encryption. The jump is worthwhile when you need weeks of lectures, interviews or meetings captured without daily offloading, or when you require password protection for sensitive material. If your work fits on a 4 GB device and you never use voice activation, the extra capacity and security features will go unused.

Capacity and Practical Limits

The 136 GB space holds roughly 9000 hours of MP3 recordings at 32 kbps, dropping proportionally at higher bit rates such as 1536 kbps WAV. The 1100 mAh lithium-polymer battery delivers up to 68 hours of continuous MP3 recording at 32 kbps before recharging via USB 2.0. Files transfer through the USB-C connector and playback uses a 3.5 mm headphone jack; there is no wireless connectivity or smartphone app integration.
