Bosch GPB 18V-1 C Professional – Cordless Bluetooth Jobsite Radio (Bare Tool)

The Bosch GPB 18V-1 C speaker is a compact and robust Bluetooth speaker designed for construction sites: it allows music playback via Bluetooth or through the Multi-Speaker Sound function, and also acts as a USB-C charger for mobile devices.

The Bosch GPB 18V-1 C has been designed to withstand typical construction site conditions, while offering good audio quality and versatility of use. With the Multi-Speaker Sound system, multiple compatible units can be connected to expand sound coverage.

The device is compatible with the Bosch Professional 18V system (and with the AMPShare alliance), so it can use batteries from the same platform.
Alternatively, it can be powered with a USB-C power supply with Power Delivery (PD).

Thanks to its compact and lightweight design (0.7 kg without battery), it is easy to transport to the worksite.
In addition, the GPB 18V-1 C integrates a USB-C port that allows you to charge an external device (max 5 V, 3 A) such as a smartphone, while playing music.

The nominal output is 11 W for the mid-range speaker, accompanied by passive radiators to enrich the sound.
There is no support for playback from USB (memory), it is only via Bluetooth or Multi-Speaker Sound.

Ideal for:

• Those working on construction sites who want to bring music safely and compatible with their Bosch platform

• Teams that want to synchronize multiple speakers (Multi-Speaker Sound) for wider coverage

• Professionals who want an audio unit that is also useful for charging smartphones on site
