136GB Storage & 9800H Capacity

This voice recorder combines 8GB of internal memory with a 128GB TF card slot for a total of 136GB capacity. It supports WAV recording format and MP3 or WAV playback. The large storage allows up to 9800 hours of audio files, reducing the need for frequent file management. It suits users who need long-term recording without constant transfers.

600H Continuous Recording

A 3500mAh lithium-ion battery powers up to 600 hours of continuous recording on a single charge. This equals roughly 25 days of non-stop operation, making it practical for extended lectures, meetings or fieldwork. The recorder uses DSP5.0 noise cancellation for clearer capture during sustained sessions. It is not suited for buyers who need multi-day recording without any charging opportunity beyond 600 hours.

USB-C Interface & Magnetic Mount

Data transfer and charging use a USB-C connector, which also serves as the headphone output. A built-in strong magnet allows quick attachment to metal surfaces for hands-free placement. The device does not offer wireless connectivity or additional mounting options beyond the magnetic back. Users who require network sync or tripod threads will need a different solution.

Questions about this item

How much heat or noise does the recorder produce during a full 600-hour continuous session?

The recorder has no fan or moving parts, so it runs silently and generates negligible heat even after 600 hours of continuous recording.

What must I already own to transfer or play back the 136 GB of WAV files?

You need a computer or mobile device with a USB-C port to connect the recorder and access the stored audio files.

Will the magnetic back interfere with older credit-card-striped badges or cassette dictation machines I still use?

The built-in magnet is designed for mounting convenience; keep magnetic-striped cards and legacy tape devices a short distance away to avoid any interference.
