Battery Life and Silent Operation

A 1100 mAh lithium polymer battery delivers up to 68 hours of continuous MP3 recording at 32 kbps on a single charge. The unit has no moving parts and runs completely silently during capture. Power consumption is low enough to cover back-to-back meetings or full lecture days without recharging. Timed and segmented recording modes help manage power use across long sessions.

Compact Build with USB 2.0 and 3.5 mm Jack

The recorder measures 0.47 by 1.45 by 4 inches and weighs 100 grams, fitting easily in a pocket or bag. A side switch enables one click record and save even from a powered off state. Files transfer via a USB 2.0 connection to a computer. A 3.5 mm headphone jack allows immediate playback monitoring, and the 1.44 inch display shows status and menus clearly.

Questions about this item

How do I install the included 128 GB TF card so the recorder uses the full 136 GB?

Insert the supplied 128 GB TF card into the card slot until it clicks; the device then combines it with the 8 GB built-in memory for 136 GB total capacity.

What battery maintenance will this recorder need later?

The 1100 mAh lithium-polymer cell is sealed inside; when its 68-hour runtime drops noticeably, the whole unit must be sent for professional battery replacement.

What limit appears first during a long continuous recording session?

The 1100 mAh battery reaches its 68-hour continuous-recording ceiling before the 136 GB storage fills.
