Direct replacement for Samsung NP730QCJ

This iTekiro AC adapter replaces Samsung part numbers AD-4019SL, BA44-00272A, BA44-00278A, BA44-00279A, CPA09-002A, EP-TA670DBUGUS, KSAS0501900200HM, PA-1400-14 and PA-1400-24. It powers the laptop and charges the battery whether the system is on or off. The right-angle DC connector reduces strain on the power jack and extends connector life. A ruggedised case seals against moisture and high humidity for mobile use.

Suitable for owners of the listed Samsung models

Buyers with different laptop models or different DC tip sizes should look elsewhere. The adapter accepts AC 100-240 V at 50-60 Hz for worldwide mains compatibility. It includes a 6 ft UL listed 2-prong AC cord and a 6 ft DC cord for extended reach. Internal safety features filter voltage spikes and limit output to protect the notebook.

Right-angle DC tip protects the laptop power jack

The 90-degree elbow design places less stress on the connector than a straight tip, helping prevent damage to both the adapter and the laptop socket. This single mechanical feature determines whether the adapter fits and lasts in daily mobile use. The sealed, ruggedised housing adds durability in harsh environments.

Questions about this item

How do I install the iTekiro AC adapter and which step do people often get wrong?

Connect the 6 ft 2-prong AC cord to the wall outlet then plug the 6 ft DC cord with its 90-degree L-shape tip into the laptop; the common mistake is forcing the right-angle connector in upside down instead of aligning the keyed shape.

What maintenance or replacement will this adapter need later?

The UL-listed AC cord and ruggedized case are built for long service; if the DC cord frays near the right-angle tip or the internal surge filter degrades after years of 100-240V input cycles, replace the whole unit.

What limit appears first under sustained use?

Continuous operation at full load is limited by the internal safety circuits that clamp output voltage and current to protect the laptop; the adapter will throttle or shut down before overheating.
