The 205mm x 90mm plastic body is shatter-resistant, water-proof, shock-absorbent, and dust-proof, and it comes in black, red, silver grey, or green. With a 10-metre effective Bluetooth range and a frequency response of 60Hz to 15kHz, it is designed for general users who need a rugged, portable speaker.
Features and Construction
The speaker is built around a plastic shell and box, with a button-based operation mode. It includes two speakers and a 20W output, supported by a signal-to-noise ratio of at least 75dB.
Material and Build
The shell and box are both made from plastic, which keeps the unit lightweight and moulded for portable use. The construction is described as shatter-resistant, water-proof, shock-absorbent, and dust-proof, making it suitable for handling in outdoor environments. The USB interface is used for charging, and the built-in lithium battery is sealed inside the unit.
Size and Practical Fit
With an appearance size of 205mm x 90mm, the speaker is compact enough to carry in a bag or place on a shelf. It has a button adjustment method for volume and playback control. The 10-metre effective Bluetooth distance allows flexible placement in a room or outdoor area without constant reconnecting.
Uses and Placement
This speaker is suitable for general users, including sports and outdoor activities, thanks to its portable size and protective features. It can also serve as a home audio device for everyday listening.
Event or Professional Use
With 20W output and two speakers, the unit can fill a small outdoor space or event area with sound. The 6-hour playing time supports longer sessions, and the power bank function can recharge a phone or other device during use. The SD card slot allows playback without a Bluetooth connection, which is useful when a paired device is not available.
Everyday Home Use
At home, the speaker can be placed on a table or shelf and controlled via buttons. The Bluetooth 5.0 connection provides a stable link to phones, tablets, or computers within 10 metres. The water-proof and dust-proof design helps protect the unit in kitchens, gardens, or workshops where splashes or dust may occur.
Benefits and Buying Value
The combination of a built-in battery, power bank function, and protective construction offers practical value for users who need a single portable audio device for multiple settings.
Reuse and Low Maintenance
The built-in 1800mAh lithium battery is rechargeable via USB, so there is no need for disposable batteries. The plastic shell can be wiped clean, and the dust-proof and water-proof features reduce the risk of damage from everyday exposure. No special care instructions are provided in the source text.
