Replacement AC adapter for Lenovo IdeaCentre Q190

This 19 V 65 W adapter replaces the original power supply for Lenovo IdeaCentre Q190 mini desktops. It matches the factory specifications for models 57312240, 57316188, 57327830 and 57312245. The unit is brand new and built with 100 % new components. It delivers reliable power for daily desktop use.

10 ft total cord length for flexible placement

The combined AC and DC cable length reaches 10 ft, letting you position the desktop farther from a wall outlet. World-wide input of 100-240 VAC at 50/60 Hz means it works on mains voltage worldwide without a separate converter. Built-in over-current, over-voltage, short-circuit and total-power protection guards the system against electrical faults. No extra mounting hardware or software is required.

Safety certifications and smart-chip protection

The adapter carries FCC, CE and RoHS certifications, confirming compliance with international safety and environmental standards. A smart chip provides overheating protection while anti-interference materials improve signal isolation. Over-charge and over-discharge safeguards further protect connected hardware. These features replace the need for an external surge protector in most office environments.
