Soundcore Boom 2 Plus Outdoor Bluetooth Speaker — Phantom Black (Model A3134)
The Soundcore Boom 2 Plus is a 140W boombox-format outdoor Bluetooth speaker built for parties, beach gatherings, and any setting where portable audio needs to fill a large space. Its 2+2 driver architecture — two 50W woofers and two 20W tweeters — delivers genuine stereo separation with dedicated crossover technology, while BassUp 2.0 extends bass response to 40 Hz and boosts output from 100W to 140W at the press of a button. The built-in 10W USB-C power bank, AUX input, IPX7 waterproof rating, and PartyCast 2.0 support for over 100 speakers position the Boom 2 Plus as a feature-complete outdoor audio solution rather than a basic portable speaker.

Use Cases
Outdoor Parties, Beaches, and Pool Gatherings
At 140W with BassUp 2.0 and twin passive radiators, the Boom 2 Plus fills outdoor spaces that a compact portable speaker cannot. The IPX7 rating handles poolside splashes and rain, and the floatable design ensures the speaker survives accidental drops into the water. PartyCast 2.0 scales the audio across multiple speakers placed at distance — eliminating coverage gaps across larger outdoor areas. The music-synced passive radiator light show adds a visual element without requiring separate lighting hardware.
Outdoor DJ and Events with Wired Sources
The 3.5 mm AUX input connects mixers, DJ controllers, turntables with a line-level preamp, and any device that outputs analogue audio — making the Boom 2 Plus compatible with wired audio workflows that Bluetooth-only speakers cannot accommodate. Two units in TWS mode provide left/right channel separation for a more spatial sound experience. PartyCast 2.0 further extends coverage across a larger event footprint without additional cabling.
Camping and Multi-Day Outdoor Trips
The 20-hour battery at moderate volume covers multiple camping days between charges, and the built-in 10W power bank keeps phones topped up in areas without mains electricity — a practical feature for navigation, photography, or emergency communication. The detachable carry strap supports shoulder carrying or hanging the speaker from a hook or branch. The auto-off function prevents battery drain during unattended periods at camp.
Home Outdoor Entertaining and Garden Use
The boombox form factor suits fixed placement on a garden table, deck, or patio, while the carry strap makes repositioning easy between indoor and outdoor spaces. AUX connectivity allows the Boom 2 Plus to function as an output for a TV or stereo receiver without requiring a Bluetooth pairing step. The soundcore app’s EQ customisation adapts the sound profile to the listening environment — boosting treble clarity for background music or maximising bass for dancing.
Considerations
Battery, Weight and Charging
Battery life drops significantly with BassUp and lights active. The 20-hour figure applies at 50% volume with BassUp off and lights off. Running BassUp at high volume with all eight light effects active will reduce playtime substantially — plan for 8–12 hours under heavy outdoor party conditions. The battery’s long runtime across moderate-use sessions makes the Boom 2 Plus well-suited to camping; for party use, the 30W fast charge recovers capacity in 3 hours.
At 3.81 kg this is a carry-and-place speaker, not a pocket portable. The Boom 2 Plus suits transport by car to a beach, campsite, or garden rather than daily carry in a backpack. The detachable strap handles short-distance carrying. Buyers seeking comparable output in a lighter chassis should consider the Boom 3i, which delivers 50W at 780 g.
A 30W Power Delivery charger is recommended but not included. Standard 5W or 10W adapters charge the Boom 2 Plus but extend charge time well beyond 3 hours. Budget for a suitable USB-C PD charger if one is not already available.
Audio and Waterproofing
IPX7 protection requires the port cover fully sealed before water exposure. The waterproof seal depends entirely on the USB-C port cover sitting flush and locked. An unsecured cover compromises the rating. After any water exposure, dry the cover and port thoroughly before charging.
AUX input is line-level. Connecting a turntable without a built-in phono preamp produces very low volume output. A dedicated phono preamp between the turntable and the Boom 2 Plus resolves this.
Frequently Asked Questions
How long does the Soundcore Boom 2 Plus battery last?
Up to 20 hours at 50% volume with BassUp off and lights off, tested in Soundcore’s laboratory. At higher volumes with BassUp and lights active, real-world playtime falls significantly — expect 8–12 hours under typical outdoor party conditions.
Does the Soundcore Boom 2 Plus charge other devices?
Yes. The USB-C port on the rear of the speaker outputs 10W (5V/2A), which charges phones and other small devices. This power bank function works when the speaker is on. The speaker itself charges via the same USB-C port using the input charging cable.
Can I connect the Boom 2 Plus to a mixer or DJ controller via cable?
Yes. The 3.5 mm AUX input accepts a standard line-level audio signal from mixers, controllers, or any analogue audio source. Note that turntables without a built-in phono preamp output a very low signal that requires a separate preamp before connecting to the AUX port.
How do I pair two Boom 2 Plus speakers for stereo sound?
Turn on both speakers. Press and hold the Bluetooth button on both simultaneously until the indicator light flashes white on each. Both speakers emit a confirmation sound, and the main speaker’s light turns blue while the secondary speaker’s light turns white. The main speaker becomes the left channel and the secondary becomes the right channel.
Does the Boom 2 Plus work with older PartyCast 1.0 speakers?
Soundcore’s FAQ does not specifically list PartyCast 1.0 backward compatibility for the Boom 2 Plus. Confirm with your regional Soundcore distributor or the soundcore app before attempting to link with older PartyCast 1.0 devices.
Is the wall charger included?
No. The box includes a 60 cm USB-C to C cable and a detachable carry strap, but no wall charger. A 30W USB-C Power Delivery charger charges the Boom 2 Plus fully in approximately 3 hours. Lower-wattage chargers extend this time.
