Full Description

A hidden recorder that still charges USB devices

REC-CHARGER combines local audio recording with a working 5 V/2 A USB charger for compatible phones, tablets and other USB devices. Its black housing has a discreet appearance, with no conspicuous openings. A small pinhole provides access to the internal activation button.

The unit measures 70 × 44 × 23 mm, approximately 2.76 × 1.73 × 0.91 inches. Recordings are stored internally as variable-bitrate MP3 files. PC software handles audio quality settings, activation sensitivity, and date and time.

Automatic microphone level control

The ALC preamplifier adjusts the microphone signal as sound levels change. Speech clarity also depends on distance, background noise and recorder placement.

Five voice-activation settings

VOX / VAS starts recording when sound exceeds the selected threshold. Five sensitivity levels let you adjust the response to the room. Each recording period is saved separately, making it easier to locate audio by date and time.

Access recordings through the coded USB cable

To activate the recorder, press the internal button through the small pinhole with a pin, similar to a SIM-eject tool. The supplied coded USB cable is used to change settings and download recordings to a PC.

Up to 100 hours of recording on battery power

The built-in rechargeable lithium-ion battery supports up to 100 hours of recording under ideal conditions. Actual runtime varies with use. A full recharge takes approximately four hours.

POWER SLEEP reduces power consumption during idle periods, with up to 2,000 hours of standby under ideal conditions. Actual standby time varies with use and sound activity.

300-hour audio storage capacity

The internal memory holds up to 300 hours of audio. AC power lets the recorder use that storage capacity without depending on battery life. When unplugged, recording time is up to 100 hours under ideal conditions; the memory capacity does not change.
