Replacement AC adapter with 100–240 V worldwide input, 6.5 ft cord and over-voltage, over-current and short-circuit protection
This AC/DC adapter replaces the original power supply for the Companion model CDT112JU-48. It accepts worldwide input voltage from 100 to 240 VAC at 50 or 60 Hz. The unit is a Class 2 transformer with a total cord length of 6.5 ft. It is supplied new with FCC, CE and RoHS certifications.
This adapter suits users who need a compatible replacement for the specific Companion model listed. It is not intended for buyers who require a different output voltage or connector type. Builders looking for a universal multi-tip charger or a higher-wattage unit for other devices should look elsewhere.
Installation requires only connecting the mains cable to a wall outlet and the output plug to the laptop. Integrated safeguards include over-current, over-voltage, short-circuit and total power protection. A smart chip provides overheating protection and anti-interference isolation. The 6.5 ft cord allows flexible placement without strain.

No published specifications for this item yet.
Yes, it is built as a replacement charger for the Companion model CDT112JU-48 and is listed as 100 % compatible with that device.
The adapter ships with its own 6.5 ft power cord, so no separate mains cable is required.
The built-in smart chip provides overload, over-voltage, short-circuit and over-temperature protection; if the laptop charges without triggering those safeguards the unit is working as intended.
