Blackbox Voice Recorder PLUS

The Voice Recorder Powerbank PLUS is a professional voice recorder, concealed in a functional power bank case. It's ideal for discreet audio recording, such as in vehicles or offices. This recorder comes standard with 8GB of internal memory, sufficient for long-term recording with automatic audio detection. For those who require additional storage, a 16GB version is available at an additional cost. Thanks to its long battery life, discreet design, and strong magnetic housing, this device is particularly suitable for use in vehicles or other spaces without constant memory management.

Who is this voice recorder suitable for?

This recorder is ideal for both professional and personal use. Think of business call recording, discreet placement in a vehicle, or capturing ambient noise in work or living spaces. Thanks to automatic volume control (ALC) and sound detection, the device operates completely independently and discreetly—without visible lights, buttons, or audio alerts.

Distinctive design with magnet and power bank look

Because the recorder looks like a regular power bank, it won't arouse suspicion. Thanks to the built-in magnet, you can easily attach the device to metal surfaces, such as under a table or car seat. This allows you to creatively position the device for optimal recording quality without it being visible.

Easy to use with slide switch

Operating the recorder is very simple. A discreet slide switch allows you to choose between continuous recording and sound detection. This setting is retained even if the device is switched off or charged. This ensures the device is quickly ready for use when needed.

Long-lasting operation and sound detection

The powerful internal battery allows for up to 14 days of continuous recording, or up to approximately 150 days of standby time with noise detection (VOX) enabled. Recording starts automatically as soon as sound is detected. This saves energy and ensures that only relevant clips are saved.

Storage capacity and file management

The device offers ample space for hundreds of audio-detection recording clips. You can manage the files on a Windows PC or macOS computer via USB, without any additional software. An optional software package is available for Android smartphones. OTG cable Available, giving you direct access to your recordings. Direct access via OTG is unfortunately not possible for iPhones, but it is possible via USB to a computer. Opting for the 16 GB version offers extra storage space – ensuring you'll have plenty of room for all your recordings, even with extended use.

Perfect for discreet use in vehicles

This voice recorder is ideal for discreet placement in a car, such as under the seat or dashboard, thanks to its magnetic design and long battery life. This allows conversations and ambient sounds in and around the vehicle to be effectively recorded, without the device being visible.
