Key Highlights
15W Powerful Sound — BassUp 2.0 with up to 92 dB peak loudness
24-Hour Playtime — up to 24 hours at 50% volume (lights off, BassUp mode), with a real-time battery display
IP68 Waterproof & Dustproof — tested against 1-metre drops
2-in-1 Silicone Strap — works as a clip or a hand strap
Built-In 4,800mAh Power Bank — emergency charging for your phone
Music-Synced Lights — 6 music-reactive modes and 8 ambient modes
Bluetooth 6.0 with TWS stereo pairing and Auracast sharing
Voice Amplifier & 92 dB Safety Alarm
The Anker Soundcore Boom Go 3i (model D5103) is a compact outdoor Bluetooth speaker that delivers 15W of bass-boosted sound from a palm-size body. BassUp 2.0 deepens the low end, and peak loudness reaches 92 dB, enough for a picnic, a hike or a room at home.
With up to 24 hours of playtime at 50% volume (and up to 40 hours in Eco Mode), you can leave the charger at home. The IP68 waterproof and dustproof body survived 1-metre drop tests, and the 2-in-1 silicone strap lets you clip it to a bag or carry it by hand.
The built-in 4,800mAh battery also works as an emergency power bank: Soundcore's lab test charges an iPhone 17 from 0% to 40% in about 60 minutes. Music-reactive lights, TWS stereo pairing, Auracast sharing, a voice amplifier and a 92 dB safety alarm (press the power button 5 times) round out the feature set. Control EQ, lighting and more from the Soundcore app.
