iTekiro 90W 19V 4.74A AC adapter for Samsung NP530 NP740 NP940

90W AC adapter for Samsung laptops

This iTekiro 90W AC adapter supplies 19V at 4.74A for compatible Samsung NP530, NP740 and NP940 series notebooks. It replaces the original charger when the factory unit is lost or damaged. The package includes a 6 ft UL-listed 2-prong AC cord and a 6 ft DC cord with a right-angle L-shape tip designed to reduce strain on the laptop socket. The unit is new and carries the supplier’s 12-month replacement warranty.

90W output with worldwide input range

The adapter delivers up to 90W from a 100–240V, 50–60Hz mains supply, making it usable on international voltages without a separate transformer. At 19V 4.74A it powers typical ultrabook-class workloads such as office applications, web browsing and video playback. Sustained heavy loads that demand more than 90W — for example discrete-GPU gaming or workstation rendering — will exceed the brick’s capacity and may cause throttling or shutdown. The 19.5V 4.62A and 20V 4.5A alternative outputs are also within the same 90W ceiling.

Barrel connector limits and safety protections

The L-shape barrel plug fits the centre-positive jack used on the listed Samsung models; it will not mate with USB-C Power Delivery or proprietary slim-tip ports found on newer ultrabooks. Built-in overload, short-circuit, over-voltage, over-current and over-temperature circuits interrupt output when fault conditions are detected, protecting both the adapter and the notebook. The 6 ft DC cable length restricts placement to within roughly 1.8 metres of the wall outlet unless an approved extension cord is used.
