Questions about this item

How much heat and noise does the 100-240VAC 50/60Hz adapter produce when running continuously?

The unit includes over-current, over-voltage and short-circuit protection plus an anti-interference design with smart-chip overheating protection, so it runs cool and silently during all-day use.

What must I already own for this WAWEIS adapter to power my modem?

You need a Westell DSL modem model B90-210030-04S2 or B90-610030-06 and a standard mains outlet; the 6.5 Ft cord plugs directly into the wall.

Will this replacement charger work reliably alongside the original Westell power supply I keep as a spare?

Yes — it is 100% OEM-compatible, meets the same FCC, CE and RoHS certifications and carries the same protection features, so both units behave identically.
