Kenuco

Kenuco 12V 4A AC/DC power adapter 5.5x2.1mm 8 tips

SKU CH-JYW7-BRZX2

A 12 V 4 A AC/DC adapter with a 5.5 × 2.1 mm barrel plug and eight interchangeable tips for powering compatible monitors, routers, mini PCs and other 12 V devices

  • TypeAC Adapter
  • Stable 12 V output powers monitors and routers reliably
  • Worldwide 100-240 V input works across regions without converters
  • ETL certification under UL standards protects against overcurrent and short circuits
  • 5 × 2.1 mm barrel plug with eight tips fits many device sockets
  • Intelligent identification matches current to each connected device

Replacement for Sceptre monitors

This 12V 4A AC/DC adapter replaces the original power supply for a wide range of Sceptre monitors including the C275B, C305B, C305W, C325B, C326B, E248B, E275B, E275W, E278W and E279W series. It also covers models rated for 3A, 2.5A and 2A outputs. The unit is ETL certified under UL standards with protection against overcurrent, overvoltage and short-circuit conditions. Worldwide 100V-240V 50/60Hz input makes it suitable for travel or relocation.

Upgrade from lower-amperage units

If your original adapter is rated at 1.25A, 1A, 2A or 2.5A, this 4A version provides additional current headroom for stable operation. The jump is worth it when a monitor flickers, fails to wake from sleep or shuts down under load with the weaker supply. It also serves as a single spare for households or offices that own multiple Sceptre models with different amperage requirements. Do not use it for devices that require a voltage other than 12V or a different connector polarity.

Plug-and-play with eight tips

The package includes eight interchangeable tips so you can match the 5.5x2.1mm barrel required by your specific monitor or device. Select the correct tip, push it firmly onto the cable until it clicks, then connect to the device before plugging into mains power. The most common mistake is choosing a tip that looks similar but has a different inner diameter or pin depth, which causes intermittent contact. Verify the polarity symbol on the device matches the adapter before powering on.
