Anker soundcore 2 A3105 Portable Bluetooth Speaker

The Anker soundcore 2 A3105 is a compact portable Bluetooth speaker listed with stereo output, battery power and a claimed 24-hour battery life. Its advertised 12W output conflicts with a separate 50-watt maximum-output listing, so buyers should not treat the higher figure as settled.

What to know before buying

Listing details to confirm

Output-power information conflicts: the title and feature copy claim 12W, while product details state 50 Watts maximum. The listing also gives battery capacity as 24 Hours in one field and separately claims a 5,200mAh Li-ion battery, and it lists Bluetooth range as both 10 Meters and 66 Feet. The stated Floor Standing mount and 10 Centimeters speaker size do not clearly describe this portable speaker. Confirm these listing details before relying on them.

Frequently asked questions

How much output power does the soundcore 2 A3105 provide?

The title advertises 12W stereo sound, but the product details list a 50 Watts maximum output. The supplied listing does not resolve this discrepancy.

What battery life is listed?

The listing claims 24 Hours. It does not specify the listening conditions behind that figure.

Is the speaker waterproof?

The listing describes it as waterproof and claims IPX7 protection. These are manufacturer claims rather than independently verified performance.

What is included in the package?

The explicit contents list names a power cable, quick start guide and one speaker. The listing also separately claims one included C battery, which conflicts with its rechargeable Li-ion battery feature description, so check the selected package details.
