Ultra-compact 15 W portable speaker

The Soundcore Boom Go 3i D5103 is a palm-sized Bluetooth 6.0 speaker built for hikers, cyclists and campers who need loud, clear audio without the bulk of larger systems. Its IP68 rating and one-metre drop protection mean it survives rain, dust and knocks that would stop ordinary speakers.

Clip or strap mounting plus emergency power

A dual-slot silicone strap switches between clip mode for backpacks or bike frames and strap mode for hand carry, keeping the speaker secure on the move. The built-in battery can also top up a phone in a pinch, so the unit doubles as a reserve power source when outlets are miles away.

24-hour playtime with real-time battery display

A full charge delivers 24 hours of music at moderate volume and the on-device indicator shows the exact level remaining, removing guesswork on long trips. At maximum output the 15 W amplifier pushes 92 dB peak loudness, but bass extension below 80 Hz and stereo imaging are limited by the single-driver design.

Questions about this item

How long will the 24-hour battery last when playing at the 92 dB peak level?

The 24-hour playtime is rated at moderate volume; running continuously at the 92 dB peak will reduce actual runtime.

Does the IP68-rated enclosure stay cool enough to touch after a full day of 15 W output?

The speaker is designed for sustained outdoor use and its compact active design dissipates heat without becoming uncomfortably hot.

What device do I need to pair with the Bluetooth 6.0 connection for the first setup?

Any smartphone, tablet, laptop or television with Bluetooth capability will pair directly — no extra hub or app required.
