DIY Retro Mini Portable Card Speaker with Bluetooth and USB Playback

This retro-styled mini card speaker brings practical audio output in a compact, portable design. Whether you need background music while working or a small speaker for a picnic, it connects wirelessly via Bluetooth with a 10-metre range. It can also play audio directly from a USB drive, offering flexible playback options without relying on a phone. The built-in lithium battery charges in 2-3 hours and powers up to 5W of output, enough for personal listening or casual small-room use. Available in five colours, this plastic-bodied speaker is lightweight and easy to slip into a bag.

Features and Construction

The speaker combines a simple retro aesthetic with modern connectivity. Its plastic shell keeps weight low, and the compact size fits in a pocket or small compartment.

Material and Build

The housing is made from plastic, which keeps the speaker lightweight and portable. Dimensions of 70 x 110 x 50 mm mean it takes up minimal space, suiting travel or desktop use.

Size and Practical Fit

At this size, the speaker sits easily on a shelf, desk, or in a bag. The card shape means it slides into a laptop case or handbag without adding bulk.

Uses and Placement

This speaker suits a variety of casual audio needs, from home office background music to outdoor gatherings where carrying larger speakers is impractical.

Event or Professional Use

For small events, presentations, or craft fairs, the Bluetooth and USB functions let you play music or audio clips without complex setup. The 10-metre range gives flexibility to move around.

Everyday Home Use

At home, use it in the kitchen, bedroom, or bathroom (away from water) for podcasts, radio streams, or phone music. Its small size means it won’t clutter surfaces.

Benefits and Buying Value

The speaker offers straightforward value through its dual playback modes and built-in rechargeable battery, reducing the need for disposable cells or constant mains power.

Reuse and Low Maintenance

The lithium battery is rechargeable via USB, so you don’t need to buy batteries. A full charge of 2-3 hours gives the speaker life for several uses before needing a top-up.

Why Choose This Product

If you need a small, affordable speaker that works with both Bluetooth and USB sources, this model covers both bases. The colour options also let you match it to your existing gear or décor.
