Compact recorder for long sessions

The AMOI B800Li is a pocket-sized voice recorder with 128 GB of internal storage and a 1500 mAh battery rated for 300 hours of continuous recording. It captures WAV audio at 32 to 384 Kbps and supports voice-activated or manual start modes. A single charge delivers up to 20 days of operation, making it suitable for lectures, interviews or extended field notes.

USB 2.0 charging and file transfer

The device connects via micro USB 2.0 for charging and for moving recordings to a computer where it appears as a mass-storage drive. No separate speaker is fitted, so playback requires headphones or a host device. The clip-on body measures 65 by 32 by 17 mm and weighs 60 g, leaving plenty of room in a shirt pocket or bag. A built-in high-sensitivity microphone is rated to pick up sound from 60 metres away.

128 GB capacity with voice activation

The 128 GB memory holds roughly 380 hours of WAV files at the highest bit-rate, and voice-activated recording pauses during silence to stretch that headroom further. Low-power auto-save protects the current file if the battery runs out. Buyers who need on-device playback through a speaker or who want wireless file transfer will need a different recorder.
