Description

Replacement power jack compatible with ASUS U31F and U31JG laptops, model PJ340903. Rated for 19V and 3.42A, this DC connector restores the power inlet used to connect the external adapter to the laptop. The component is intended for repair and refurbishment of laptops with a damaged, loose or intermittently working power socket. Installation requires disassembly of the laptop chassis and basic soldering or connector replacement skills.

Advantages

This power jack provides a direct, form-fit connection designed to match the original power inlet dimensions and electrical rating of 19V and 3.42A. It offers a stable electrical contact to reduce power interruptions caused by worn contacts or broken housings. The replacement part allows repair of the laptop without replacing the entire power adapter or motherboard, which can lower repair costs and extend device service life.
