136GB Magnetic Voice Recorder

The Zutiifeu US-SD provides 136GB of combined storage through 8GB of built-in memory and a 128GB TF card. It records in WAV format and offers up to 9800 hours of capacity for lectures, meetings, or classes. The device connects via USB-C for data transfer and headphone monitoring.

DSP5.0 Noise Cancellation & Magnetic Mount

The recorder uses DSP5.0 noise cancellation to capture clearer audio in noisy environments. A built-in magnet allows attachment to metal surfaces for discreet or hands-free placement. One-button operation handles recording start, stop, and save functions without complex menus.

USB-C Interface & 200mAh Battery Limits

The USB-C port handles both file transfer and audio output, requiring a compatible host or adapter. The internal 200mAh lithium-ion battery limits continuous runtime between charges. Buyers needing wireless file transfer or smartphone app control should look elsewhere.

Questions about this item

Can the 128 GB TF card be swapped out when it fills up?

The recorder ships with a 128 GB TF card installed; removing and replacing it with another card is possible, letting you offload recordings and continue capturing new audio.

How long can the 200 mAh lithium-ion battery power continuous recording?

The 200 mAh cell is rated for up to 9800 hours of total recording capacity, though actual continuous run-time per charge will be lower and depends on the DSP 5.0 noise-cancellation load.

Does the USB-C connector get warm during all-day recording sessions?

The USB-C port is used for charging and data transfer only; under normal all-day use the recorder body stays cool because the 200 mAh battery and DSP 5.0 processing draw minimal power.
