WAWEIS 18V 3.5A AC Adapter 10ft Cord

SKU CH-YJQ1-T3NV3

Replacement 18V 3.5A AC adapter with 10ft cord and worldwide 100-240V input for Brookstone Big Blue Party X speaker

  • World-wide 100–240 VAC input works on any mains supply
  • 10 ft total cord length gives flexible placement
  • 18 V 3.5 A output matches the speaker’s original power spec
  • FCC, CE and RoHS certifications confirm safety compliance
  • Over-current, over-voltage, short-circuit and over-temperature protections guard the device

Direct replacement for Brookstone Big Blue Party X

This 18 V 3.5 A AC adapter is built as a direct replacement for the Brookstone Big Blue Party X wireless Bluetooth speaker models 326174 and 326172. It supplies the exact voltage and current the original unit requires. The 10 ft power cord gives generous placement flexibility. Safety certifications include FCC, CE and RoHS.

Steady output during extended playback

The adapter maintains its rated 18 V 3.5 A continuously while the speaker runs at high volume for long sessions. Over-current, over-voltage and short-circuit protection circuits engage instantly if the load exceeds design limits. World-wide 100-240 VAC 50/60 Hz input allows use on any mains supply without a separate converter. The smart chip monitors output stability throughout the charge cycle.

Cool, quiet operation from quality components

High-grade wires and isolation materials keep the housing cool to the touch during normal use. No fan is present, so operation is completely silent. Over-heating protection shuts the unit down safely if internal temperatures rise abnormally. The 10 ft cord reduces strain on the connector and helps keep the adapter positioned in open air for natural convection.

Questions about this item

Does the 18 V 3.5 A output run hot during all-day use?

The adapter includes overheating protection with a smart chip and short-circuit protection, designed to stay within safe thermal limits during continuous operation.

What must I already own for this 18 V 3.5 A supply to work?

You need the Brookstone Big Blue Party X speaker (models 326174 or 326172) that requires an 18 V DC 3.5 A input with a compatible barrel connector.

Will this 10 ft cord adapter work with my older Brookstone speaker that uses the same 18 V 3.5 A spec?

Yes, it is 100 % compatible with the listed Brookstone models and matches the original 18 V 3.5 A specification, so older units with that rating will operate normally.
