Soundcore Boom 2 vs Bose SoundLink Plus: Which Portable Speaker Fits Your Setup?

Boom 2 fits a buyer comfortable with 5W USB-A phone output who wants Soundcore's documented group modes or a built-in handle. SoundLink Plus fits a buyer who values its documented 15W USB-C output, strap attachment, or Bose speaker linking. These are feature and setup differences, not sound-quality, measured charging-speed, or durability results.

The buying question

Which speaker better fits your phone top-up needs, carry method, and plans to link additional speakers?

SoundLink Plus documents 15W USB-C charge-out and a strap that can attach to a carabiner or cord; Boom 2 documents 5W USB-A output, a built-in handle, and Soundcore linking modes. These feature differences do not establish sound quality, actual charging speed, or durability superiority.

Quick verdict

Choose Soundcore Boom 2 (A3138) if

  • 5W USB-A output is enough for your phone and you want the documented Soundcore TWS or PartyCast setup.
  • You prefer a built-in handle and do not need the strap-to-carabiner/cord method documented for Bose.

Choose Bose SoundLink Plus if

  • Your phone supports charging from a 15W USB-C supply and that output is useful to you.
  • You want the documented strap attachment option or plan to link one compatible Bose speaker.
When the recommendation changes
  • If your phone can use a 15W USB-C supply, Bose documents that output; if 5W USB-A is sufficient, Boom 2 documents that option. Check the phone manual and cable before relying on either speaker as a charger.
  • If adding speakers later, choose for the system you expect to use: Boom 2's guide describes TWS for two identical Soundcore speakers and PartyCast for compatible models; Bose documents linking one other compatible Bose speaker at a time.
  • If attachment to a bag or cord matters, Bose documents using its strap with a carabiner or cord; Boom 2's guide identifies a built-in handle. The IP ratings are not interchangeable, and Boom 2's IPX7 entry does not establish dust performance.

The differences that matter

Phone Charging While Away From An Outlet

Soundcore Boom 2 (A3138)

The A3138 manual identifies a USB-A output and rates DC output at 5V/1A (5W); it says the speaker can charge mobile devices or accessories.[1]

Bose SoundLink Plus

Bose documents USB-C charge-out at 15W (5V/3A) for typical phones and tablets; larger devices such as laptops or power banks may not charge, so Bose advises checking the device manual.[2, 3]

What this changes: This is a difference in documented port and output rating, not a measured charging-speed comparison. Match the port, cable, and output to the phone's own charging requirements before treating either speaker as a power source.[1, 2, 3]

The better fit depends on your priorities

Multi Speaker Grouping Workflow

Soundcore Boom 2 (A3138)

The A3138 guide describes TWS stereo linking between two identical Soundcore speakers and PartyCast linking with other Soundcore models that support PartyCast.[1]

Bose SoundLink Plus

The SoundLink Plus guide describes linking one other compatible Bose Bluetooth speaker at a time. It says same-model speakers can use Stereo mode and different compatible Bose models use Party mode; speakers and the streaming device should each be within 30 ft (9 m) as specified.[3]

What this changes: If you plan to expand later, buy into the ecosystem you expect to use and check the exact companion-speaker models before pairing. Boom 2's TWS instructions require an identical speaker, while its PartyCast instructions require PartyCast support; Bose documents one compatible Bose speaker at a time with mode depending on whether models match.[1, 3]

The better fit depends on your priorities

Environmental Protection And Carry Context

Soundcore Boom 2 (A3138)

The A3138 guide labels a built-in handle and lists IPX7 as its water-protection rating.[1]

Bose SoundLink Plus

The Bose guide says its strap can be used as a finger loop or attached to a carabiner or cord. It lists IP67 and IP64 and specifies immersion up to 30 minutes at up to 1 m (3.3 ft).[3]

What this changes: Choose by the carry method you will use: Boom 2 has a documented built-in handle, while Bose documents a strap attachment for a carabiner or cord. For exposure requirements, compare the exact published conditions with your use; the IPX7 listing for Boom 2 does not establish dust performance, and these ratings do not prove comparative durability.[1, 3]

The better fit depends on your priorities

Best for your routine

A speaker used to top up a phone whose manual permits charging from the Bose's documented 15W USB-C output.

Best fit: Bose SoundLink Plus

Based on listed features, not comparative testing.

Bose documents 15W (5V/3A) USB-C output for typical phones and tablets, while the Boom 2 manual rates its USB-A output at 5W. Confirm the phone's requirements and cable; this is not a measured speed result.

A buyer expanding an existing Soundcore setup with identical or PartyCast-compatible models.

Best fit: Soundcore Boom 2 (A3138)

Based on listed features, not comparative testing.

The A3138 manual documents TWS with two identical Soundcore speakers and PartyCast with compatible models. Confirm the companion model's PartyCast support; this is a feature-fit recommendation, not a sound-quality result.

Value and trade-offs

One or both observed offers have eligibility conditions, so no unrestricted price difference is shown.

No comparable price-history basis was established; compare current checkout offers and package details before choosing.

Limitations

  • No controlled side-by-side sound, battery-runtime, charging-speed, or durability testing was used; published specifications do not establish which speaker sounds better or charges a particular phone faster.
  • The Boom 2 A3138 manual lists IPX7 and does not establish a dust rating. Do not read that notation as proof that it lacks dust protection; check with Soundcore if a dust rating is a purchase requirement.
  • Soundcore's manual says TWS uses two identical speakers and PartyCast uses PartyCast-enabled models; confirm the exact companion model and hardware revision before expanding a setup.
  • Bose says typical phones and tablets can charge from its 15W output but larger devices may not; check your device manual and cable. Bose also says to keep the USB-C port fully dry before charging.

Questions shoppers ask

Can either speaker charge a phone?

Both manuals describe charging external devices. Boom 2's A3138 guide rates USB-A output at 5V/1A (5W). Bose documents 15W (5V/3A) USB-C output for typical phones and tablets, with larger devices potentially unsupported. Check the phone manual and cable; no actual charge-rate test was conducted.

Can I link a Soundcore Boom 2 with a Bose SoundLink Plus?

The cited guides describe Soundcore TWS/PartyCast and Bose speaker-linking within their respective compatible models. They do not document cross-brand linking between these speakers, so do not assume that they can join one group.

What carry and ingress details should I check?

The A3138 guide identifies a built-in handle and lists IPX7. Bose documents a finger-loop strap that can attach to a carabiner or cord and lists IP67/IP64, including immersion up to 1 m for up to 30 minutes. The ratings and carry methods differ; Boom 2's IPX7 entry does not establish dust performance, and neither listing is a comparative durability test.
