SKU CH-6B8R-CEXN1 MPN LK-DC-120100

A 12 V replacement AC adapter delivering 0.8 A to 1 A with worldwide 100–240 V input, 6.5 ft cord and FCC, CE, RoHS certification

  • World-wide 100-240 V input works across mains standards
  • 5 ft cord gives flexible placement at the desk
  • Multi-layer protection guards against over-current, over-voltage and short circuits
  • FCC, CE and RoHS marks confirm regulated safety compliance
  • 12 V output at .8-1 A matches original charger specification

12V AC/DC Power Adapter

This 12V AC/DC adapter replaces the WAWEIS LK-DC-120100 unit. It accepts a wide 100-240VAC input at 50/60Hz and delivers a regulated 12VDC output at 0.8A to 1A. The package includes a 6.5 ft power cord for flexible placement. Built-in safety circuits provide over-current, over-voltage, short-circuit and total-power protection.

Who This Suits And Who It Does Not

The adapter suits owners of devices that require the exact LK-DC-120100 model or the listed WT-AD18W120080U cross-reference. It is not suitable for hardware needing a different voltage, a higher current rating or a proprietary connector not covered by the compatibility list. Buyers who want more power capacity or a different output specification should look at another unit.

Output Current Range Decides Fit

The critical specification is the 0.8A to 1A output range at 12V. Match this range to the original charger label on the laptop or peripheral before purchase. FCC, CE and RoHS certifications confirm regulatory compliance for the markets where those marks apply.

Questions about this item

How often will the 12V 0.8A-1A AC adapter need replacement under normal use?

The unit is built with new components and includes over-current, over-voltage, short-circuit and overheating protection to extend service life. No scheduled maintenance is required; replace only if output becomes unstable or physical damage occurs.

What is the first limit reached when the adapter runs continuously at full load?

The 12V output is rated for a maximum of 1A (1000mA). Sustained loads above this will trigger the over-current protection, which is the primary limiting factor during extended operation.

How much heat and noise does the Class 2 power supply produce during all-day operation?

The adapter uses a smart chip and isolation materials for overheating protection and anti-interference. It operates silently with no fan; the enclosure warms under load but stays within safe limits for a Class 2 device.
