Anker Soundcore Boom Go 3i Portable Speaker

Pocket-Sized Power for Outdoor Adventures

The Soundcore Boom Go 3i by Anker is a palm-size portable Bluetooth speaker engineered for hikers, cyclists, and beachgoers who refuse to trade sound quality for portability. Despite its compact frame, this model pushes 15W of output with BassUp 2.0 technology and 92 dB peak loudness that fills a garden, campsite, or small room. The Soundcore Boom Go 3i is the right choice for active listeners who need a rugged everyday speaker that doubles as an emergency phone charger.

What Sets It Apart

Two features make this speaker stand out in its category. The 2-in-1 silicone strap transforms between clip mode (attach to a backpack or bike handlebar) and strap mode (for handheld carry), using soft, tear-resistant silicone. Built into the chassis, a 4,800 mAh battery doubles as an emergency power bank, capable of charging an iPhone 17 from 0% to 40% in roughly 60 minutes.

Technical Specifications

Every spec on the Boom Go 3i is tuned for outdoor reliability. The IP68 rating means full dust-tight sealing plus continuous water submersion protection, while 1-meter drop testing covers the inevitable trail mishaps. Bluetooth 6.0 delivers a stable 30-meter wireless range, and the 5.3 cm driver paired with BassUp 2.0 produces the deep low-end that reviewers describe as "punchy" for the size.

Who It's For

This speaker suits outdoor enthusiasts and commuters who want a grab-and-go unit that survives rain, dust, and the occasional drop. Cyclists and hikers benefit from the dual-mode strap and IP68 sealing, while party hosts can pair two units in TWS mode for true stereo or connect multiple speakers via Auracast. Six music-synced light modes and eight ambient options add atmosphere to pool nights, and the customizable EQ in the Soundcore app lets listeners dial in presets for hip-hop, pop, rock, and more. At 380 g, it slips into a jacket pocket without weighing you down.
