WAWEIS 12V 3.5A AC Adapter 10ft cord

SKU CH-C00D-WA57N

Replacement 12V 3.5A AC adapter with 10ft cord and worldwide 100-240V input for compatible routers

  • World-wide 100-240 V input suits any mains supply
  • 10 ft power cord gives flexible placement options
  • 12 V 3.5 A output matches original router requirements
  • FCC CE RoHS certified for verified safety compliance
  • Over-current over-voltage and short-circuit protection guards connected hardware

Replacement Power Adapter for Linksys Router

This 12V 3.5A AC adapter replaces the original supply for Linksys Max Stream MU-MIMO Gigabit Dual-Band Smart Wi-Fi Router models KSAS0501200350HU, MU42-1120300-A1 and MU42-1120300-AI. It accepts worldwide input voltage from 100 to 240VAC at 50 or 60Hz. The unit is built with new components and carries FCC, CE and RoHS certifications.

Continuous Power Delivery Under Load

The adapter maintains a steady 12VDC output at up to 3.5A during prolonged router operation. Integrated safety circuits provide over-current protection, total power protection, over-voltage protection and short-circuit protection to prevent damage during sustained demand. A smart chip adds overload and overheating safeguards while high-quality wires and isolation materials reduce interference.

Thermal Management and Efficiency

Protection features limit heat build-up during normal use by regulating current and voltage within safe margins. The 10 ft power cord allows flexible placement away from confined spaces, aiding passive cooling. No active fan is present, so operation remains silent while the adapter supplies continuous power to the router.

Questions about this item

How much heat or noise does the 12 V 3.5 A adapter produce when powering a router continuously?

The unit has no fan and relies on passive cooling; normal operation is silent, and the casing stays warm but within safe limits thanks to over-current, over-voltage and short-circuit protection.

Which connectors or cables must I already have to use this adapter with my Linksys router?

The adapter includes a fixed 10 ft output cord with a barrel plug that matches the router’s 12 V DC input; no extra cables are required.

Will this 12 V 3.5 A supply work alongside the original Linksys MU42-1120300-A1 brick I am keeping as a spare?

Yes — it delivers the same 12 V DC at 3.5 A with identical polarity, so it can replace or supplement the original brick without any compatibility issues.
