Compatible Replacement Adapter

This AC adapter replaces the original power supply for QFX PBX-31150 and PBX-410205 portable PA speakers. It delivers reliable charging for battery-powered Bluetooth karaoke systems used in events, rehearsals or outdoor gatherings. The unit is built as a direct OEM-compatible substitute.

Upgrade From Damaged Or Lost Units

The adapter is worth buying when the factory charger is missing, damaged or no longer holds a stable charge. It restores full charging function without modifying the speaker. Buyers who need a multi-voltage travel unit for other devices should look elsewhere.

Worldwide Input With 6.5 Ft Cord

The 100-240VAC 50/60Hz input works across global mains standards, while the 6.5 ft power cord gives placement flexibility near outlets. Integrated protection covers over-current, over-voltage, short-circuit and total-power faults. It does not power speakers directly without the internal battery.

Questions about this item

Does the 6.5 ft power cord reach a standard UK wall socket from a floor-standing speaker?

The adapter includes a 6.5 ft total cord length from the wall plug to the speaker connector, suitable for typical floor-to-socket distances.

What is the correct way to connect the barrel plug to the QFX PBX-31150 charging port?

Align the centre-positive barrel connector with the speaker's DC input and push firmly until seated; the smart chip prevents damage if polarity is reversed.

When should the 100-240VAC 50/60Hz adapter be replaced under normal use?

Replace the unit if the cable shows fraying, the brick becomes unusually hot, or the speaker fails to charge despite a secure connection.
