Specifications

Soundcore officially lists the Boom Go 3i with 15W output, IP68 protection, approximately 24 hours of battery life, and a product weight of 380g.

Powerful 15W Sound with BassUp 2.0

Despite its compact dimensions, the Soundcore Boom Go 3i delivers up to 15W of audio output and reaches peak loudness levels of approximately 92dB.

Soundcore's BassUp 2.0 technology is designed to strengthen low frequencies, giving music a fuller and punchier sound than you might expect from a palm-sized portable speaker.

Whether you're listening to music around the house, relaxing outdoors, camping, or spending time with friends, the Boom Go 3i is designed to produce clear, energetic audio without requiring a large speaker.

Up to 24 Hours of Playtime

The Boom Go 3i is built for extended listening away from a power outlet.

Soundcore's laboratory figures specify approximately:

• Up to 40 hours at 50% volume with lights off in Eco Mode.
• Up to 24 hours at 50% volume with lights off using BassUp Mode.
• Up to 6 hours at 100% volume with lighting and BassUp enabled.

Actual battery life varies according to volume, EQ settings, lighting, audio content, Bluetooth usage, and other operating conditions.

The speaker also provides a real-time battery display, making it easier to check remaining power before heading out.

IP68 Waterproof & Dustproof Protection

Designed with outdoor use in mind, the Soundcore Boom Go 3i carries an IP68 dust and waterproof rating.

This helps protect the speaker during situations such as:

• Poolside Listening
• Beach Trips
• Camping
• Hiking
• Outdoor Gatherings
• Rainy Weather
• Garden & Backyard Use
• Dusty Outdoor Environments

Soundcore also states that the USB-C port itself uses an uncovered IP68-rated design. The port should be completely dry before connecting a charging cable.

Built for Drops & Outdoor Adventures

Water and dust aren't the only environmental challenges the Boom Go 3i is designed to handle.

Soundcore states that the speaker has been tested for drops of up to 1 meter / approximately 3.28 feet, adding another level of protection for everyday outdoor use.

Combined with its compact size, durable construction, IP68 rating, and flexible carrying system, this makes the Boom Go 3i well suited to travel and active lifestyles.

Music-Synced RGB Light Show

Integrated lighting adds a visual element to your music.

The Boom Go 3i features:

• 6 Music-Reactive Lighting Modes
• 8 Ambient Lighting Modes
• Customizable Light Colors
• Music-Synchronized Effects

Lighting can be customized through the Soundcore app, allowing you to adjust the speaker's appearance to suit your music, surroundings, or mood.

Turn the lighting on for parties and gatherings or switch it off when you want to maximize battery runtime.

4,800mAh Emergency Power Bank

The internal 4,800mAh battery isn't limited to powering the speaker.

The Boom Go 3i can function as an emergency portable charger, allowing you to provide additional power to a compatible smartphone or other USB device when necessary.

In Soundcore's internal testing, a fully charged Boom Go 3i supplied an iPhone 17 with up to 63% additional battery capacity, including approximately 0% to 40% in 60 minutes. Actual results depend on the connected device, operating conditions, and remaining speaker battery.

This feature can be especially useful when using your phone for navigation, calls, photos, or communication during outdoor trips.

Bluetooth 6.0 Wireless Connectivity

The Soundcore Boom Go 3i uses Bluetooth 6.0 for wireless connection with compatible devices.

Compatible device categories include:

• Android Smartphones
• iPhones
• iPads
• Android Tablets
• Laptops with Bluetooth
• Compatible Gaming Devices
• Other Bluetooth Audio Sources

Simply pair your compatible device and enjoy wireless music, podcasts, videos, and other audio without a physical audio cable.

TWS Stereo Pairing

For users who want a wider soundstage, two Boom Go 3i speakers can be paired using TWS – True Wireless Stereo.

This allows two compatible Boom Go 3i units to operate together as a stereo speaker pair, creating a more spacious listening experience than a single unit.

It can be especially useful for outdoor gatherings, larger rooms, patios, and other situations where wider sound coverage is preferred.

Auracast Multi-Speaker Connectivity

The Boom Go 3i also supports Auracast, allowing connection with multiple compatible devices that support the open Auracast standard.

Soundcore states that three or more compatible devices can be connected through Auracast for broader audio coverage.

Auracast and TWS are different connection methods, and Soundcore notes that Boom Go 3i's Auracast implementation is not compatible with PartyCast devices.

Flexible 2-in-1 Carrying Strap

A versatile silicone strap is integrated into the portable design.

The dual-slot mounting system can be configured in different ways, allowing you to:

• Carry the speaker by hand.
• Attach it to a compatible backpack.
• Secure it to suitable outdoor equipment.
• Mount it around compatible bicycle areas.
• Hang it at a campsite or outdoor setup.

The strap uses soft, tear-resistant silicone and is designed to provide greater flexibility when taking the Boom Go 3i outside.

Safety Alarm Function

The Boom Go 3i also includes an integrated emergency alarm function.

Pressing the power button five times activates a loud 92dB alarm, which Soundcore states can be heard from approximately 50 meters away under its specified conditions.

This provides an additional practical feature for activities such as hiking, camping, and other outdoor adventures.

Voice Amplification

The speaker includes a Voice Amplifier feature designed to help your voice carry over a wider area when used with a connected smartphone.

This can be useful for:

• Outdoor Gatherings
• Group Activities
• Training Sessions
• Camps
• Small Events
• Fitness Activities

Voice Amplification can be accessed as part of the Boom Go 3i's expanded feature set.

Soundcore App Control

Connect the Boom Go 3i to the Soundcore app to personalize how the speaker operates.

Available controls include:

• Custom EQ Settings
• BassUp 2.0
• RGB Lighting
• Workout Timer
• Emergency Alarm
• Voice Amplifier
• Additional Speaker Settings

This allows you to adjust both audio and functional features directly from a compatible smartphone.

Compact & Lightweight Design

At approximately 380g, the Soundcore Boom Go 3i provides substantial audio output without the bulk associated with larger portable speakers.

Its palm-sized design makes it easy to carry in:

• Backpacks
• Travel Bags
• Gym Bags
• Laptop Bags

The combination of low weight, a flexible strap, durable construction, and long battery runtime makes it particularly convenient for users who frequently take their music outside.
