Portable Bluetooth speaker with 4000 mAh battery, 20-hour call time, and 10-metre wireless range

This compact Bluetooth speaker provides a wireless audio solution designed for mobility and extended use. With a substantial 4000 mAh rechargeable battery, it delivers up to 20 hours of continuous call duration or approximately 15 hours of music playback on a single charge. The 10-metre Bluetooth transmission range allows you to place your paired phone or tablet at a distance while maintaining a stable connection. Measuring 72 mm in width, 72 mm in depth, and 170 mm in height, the speaker is sized for portability without sacrificing battery capacity. It features integrated controls for managing calls and music, along with noise reduction technology to improve audio clarity during conversations.

Features and Construction

The speaker's design centres on practical wireless performance and user-controlled operation. Its construction incorporates a rechargeable battery and Bluetooth circuitry within a housing suited for portable use.

Material and Build

The speaker's external casing is typically constructed from durable plastic, which helps keep the overall weight manageable for portability. Internal components include a 4000 mAh lithium-ion battery, Bluetooth antenna, speaker drivers, and control circuitry. The noise reduction feature is integrated into the microphone and audio processing system to filter background sound during calls.

Size and Practical Fit

With dimensions of 72 mm wide by 72 mm deep by 170 mm high, the speaker is compact enough to fit on a desk, shelf, or in a bag for transport. Its rectangular prism shape provides stability on flat surfaces. The control buttons for call management and music playback are positioned for easy access during use.

Uses and Placement

The speaker's combination of battery life, wireless range, and call features supports various personal and professional audio scenarios. Its colour options – black, blue, and red – allow it to blend in or stand out according to preference.

Event or Professional Use

For professional settings, the 20-hour call duration supports extended conference calls or remote meetings without mid-call charging. The noise reduction helps minimise background office or environmental noise transmitted to the other party. The 10-metre range permits moving around a room while keeping your phone stationary on a desk or charging pad.

Everyday Home Use

At home, the speaker can provide background music for up to 15 hours during chores, relaxing, or hosting. Its wireless design eliminates cable clutter, and the call controls allow you to handle incoming calls hands-free while cooking or doing other tasks. The compact size makes it easy to move between rooms.

Benefits and Buying Value

The primary value lies in the extended battery life and integrated call management within a portable form factor. This speaker reduces the need to be tethered to a power outlet during long usage sessions.

Reuse and Low Maintenance

The rechargeable battery supports repeated charging cycles for regular use over time. With no consumable parts aside from the battery, which is designed for long-term use, maintenance is minimal. Keeping the speaker clean and avoiding exposure to extreme moisture are the primary care considerations.

Why Choose This Product

This speaker is suited for users who prioritise long battery life for calls and music in a portable package. The specified 20-hour call time and 15-hour music playback offer clear runtime expectations, while the 10-metre range provides practical wireless flexibility. The inclusion of call controls and noise reduction adds functionality beyond basic audio playback.
