Portable outdoor subwoofer with Bluetooth 2.1 3W 100Hz-20kHz and call function

This portable outdoor subwoofer brings audio to parks, campsites, and garden spaces without the need for mains power. With Bluetooth 2.1 pairing, you can stream music from a smartphone or tablet up to 10 metres away. The built-in radio and card insertion slot add flexibility for offline listening. A 300mAh lithium battery gives 1–3 hours of playback, and the 3W driver covers 100Hz–20kHz for clear sound on compact outings. Six colour choices – Black, Blue, Camouflage, Light Blue, Red, Silver – let you match the speaker to your gear.

Features and Construction

This subwoofer packs essential functions into a portable chassis designed for outdoor use. Its single 3W speaker delivers the frequency range you need for spoken word and music.

Material and Build

The housing is made from durable plastic with a metal mesh grille protecting the driver. Push-button controls sit on top for easy access to power, volume, and mode switching. Physical dimensions are not provided, but the unit is designed to be hand-carried.

Size and Practical Fit

As a single-unit portable speaker, it fits into a backpack or cup holder. The 300mAh battery and compact footprint make it suitable for short trips where weight and space are limited.

Uses and Placement

This subwoofer works wherever a portable sound source is needed – from a picnic table to a workshop bench.

Event or Professional Use

For outdoor gatherings, market stalls, or informal presentations, the speaker provides background audio and hands-free call handling. The radio function works without a phone, saving battery on your mobile device.

Everyday Home Use

Use it in the kitchen, bathroom, or garage for casual listening. The USB charge means you can move it from room to room without trailing cables.

Benefits and Buying Value

This model offers three playback sources – Bluetooth, radio, and card – in one device, reducing the need for multiple gadgets.

Reuse and Low Maintenance

The built-in lithium battery is charged via USB, so no disposable batteries are needed. Keep the USB port dry and the grille clean to maintain performance.
