Soundcore Boom Go 3i 15W portable Bluetooth speaker with IP68, BassUp 2.0, and 24-hour battery

Big sound in a carry-anywhere body:

The Boom Go 3i produces 15W of output, hitting peaks of up to 92 dB - a solid output for its 380g frame. BassUp 2.0 processes the signal in real time to add depth and definition to the low end, and nine-band EQ with four presets in the Soundcore app lets you shape the sound to your taste.

Built for outdoor use:

IP68 certification means the Boom Go 3i is fully dustproof and can be submerged in water - it also passes a 1-metre drop test, so it handles a tumble from a backpack without issue. The 2-in-1 mount strap clips to a bag, pole, or handlebar in seconds, making it genuinely practical for hikes, cycling trips, or camping.

Battery life and power bank in one:

Rated at up to 24 hours of playtime in standard mode, or up to 40 hours in Eco mode with lights off and volume at 50%. The built-in 4,800 mAh battery doubles as a power bank via the USB-C port - Soundcore's own testing shows it charges an iPhone from flat to 40% in roughly 60 minutes.

Connectivity and multi-speaker options:

Bluetooth 6.0 maintains a stable connection at over 30 metres line-of-sight. Multipoint pairing lets two devices stay connected simultaneously, and Auracast allows multiple compatible speakers to be chained in parallel. Two Boom Go 3i units can also be linked in TWS mode for true stereo playback.

Practical extras worth noting:

A real-time LED Smart Display shows the remaining battery level at a glance rather than relying on a single status LED. Pressing the power button five times triggers an emergency alarm audible up to 50 metres away, useful in outdoor situations. Auto power-off kicks in after 20 minutes with no connected device, conserving the battery between sessions.

Setup and Care

Getting started:

Press and hold the Bluetooth button to enter pairing mode on first use. Open Bluetooth settings on your phone, select "Soundcore Boom Go 3i", and the connection is established within seconds. Download the free Soundcore app to access the nine-band EQ, Eco mode, Auracast settings, and the adjustable auto power-off timer.

Mounting and carrying:

The 2-in-1 silicone strap attaches to backpack loops, handlebars, tent poles, or railings - slide the strap through the clip slot for bag attachment, or loop it around a pole or post in strap mode. The four silicone feet on the base keep the speaker steady and reduce vibration on hard surfaces when placed flat.

Charging and power bank use:

Charge the Boom Go 3i using the included USB-C to USB-C cable with a certified charger rated between 0.05W and 15W. To use the power bank function, connect a USB-C cable from the speaker's USB-C port to your device - this works during music playback without interrupting audio.

Cleaning and care:

The IP68 rating means the speaker can be rinsed under tap water to remove dust, sand, or mud after outdoor use. Wipe down with a soft dry cloth and ensure the USB-C port is fully dry before charging. Avoid using abrasive cleaners or solvents on the silicone body or strap.
