SKU CH-5DH9-NTS8G MPN SA142A-19U

A replacement AC adapter with a 10 ft power cord, 100-240V input, and over-voltage, over-current, and short-circuit protection

  • World-wide 100-240 VAC input works across mains standards
  • 10 ft total cord length gives flexible placement
  • Over-current, over-voltage and short-circuit protection safeguards hardware
  • FCC, CE and RoHS certified for regulated safety
  • 100 % OEM compatible replacement matches original specifications

Worldwide Input Compatibility

The WAWEIS SA142A-19U is a new AC adapter designed to replace a lost or damaged laptop charger. It accepts a worldwide input range of 100-240VAC at 50/60Hz, making it suitable for use at home or during international travel. The unit includes a total cord length of 10 ft, providing flexible placement between the wall outlet and the device. Safety certifications include FCC, CE and RoHS compliance.

Target User and Limitations

This adapter suits owners of the specific Sino-American SA142A-19U model who need a direct 100% compatible replacement with built-in over current, over voltage, short circuit and total power protection. It is not for buyers who require a different output voltage, connector tip or polarity than the original unit provides. Users needing a battery pack rather than a mains power supply should look at a different product category.

Deciding Specification

The single specification that confirms fit is the exact model number SA142A-19U printed on the original charger or device label. Only a unit matching this part number guarantees the correct output parameters and connector geometry for safe operation. Verify this identifier before purchase to ensure compatibility.

Questions about this item

What input voltage range does the SA142A-19U adapter accept?

The SA142A-19U accepts a world-wide input range of 100 to 240 volts AC at 50 or 60 Hz, so it works on mains supplies in most countries without a separate voltage selector.

What cable length and plug style does the SA142A-19U ship with?

The unit includes a total power cord length of 10 ft, combining the detachable AC mains lead and the DC output cable, ending in a barrel connector that matches the original laptop jack.

How do I install the SA142A-19U and what step is often missed?

Plug the AC cord into the adapter brick, connect the barrel tip firmly into the laptop power port, then plug the mains plug into a wall socket; the step people skip is verifying the brick LED lights up before turning on the laptop.
