Direct replacement for Brookstone Big Blue Studio

This 18 V AC adapter is built as a drop-in replacement for the Brookstone Big Blue Studio wireless Bluetooth speaker. It delivers the exact voltage the speaker expects and carries FCC, CE and RoHS certifications. The unit is supplied new with a 12 month warranty.

10 ft cord frees outlet placement

A total 10 ft power cord lets you reach distant sockets without stretching or adding an extension lead. World-wide 100-240 VAC 50/60 Hz input means the same adapter works on any mains supply. Over-current, over-voltage, short-circuit and total-power protection guard the speaker and the adapter itself.

Protection circuits sustain continuous operation

Smart-chip overheating protection and anti-interference isolation keep the adapter stable during long listening sessions. Overload and over-charge/discharge safeguards prevent stress when the speaker draws peak current. Strict quality-control testing ensures the unit maintains rated output without thermal throttling.

Questions about this item

Does the 100-240VAC input handle voltage fluctuations during all-day use?

The adapter accepts 100-240VAC at 50/60Hz worldwide input, so normal mains variation is within its design range.

How hot or noisy does the power brick get after hours of continuous operation?

No fan is present; the unit relies on passive cooling and built-in overheating protection with a smart chip.

What must the Brookstone Big Blue Studio speaker already have for this adapter to connect?

The speaker needs its original 18V DC input jack; the adapter’s plug matches that port directly.
