Lenovo 40W USB-C laptop charger

The Lenovo LN-A0403A3C is a 40-watt power adapter that delivers 20 volts at 2 amps. It accepts a universal input range of 100 to 240 volts at 50 to 60 hertz. A detachable power cord is included in the box. The unit is designed for Lenovo laptops that require this specific output profile.

Replaces lost or damaged 40W Lenovo adapters

This adapter serves as a direct replacement for an original Lenovo charger carrying part number 36200411. The jump is worth it when the existing brick no longer negotiates 20 volts or shows physical wear on the cable. It is not suitable for devices that demand higher wattage or a different voltage rail.

Fits slim travel kits and desk setups

The compact form factor slips into a laptop sleeve without adding bulk. Universal voltage input means it works abroad without a separate transformer. The included mains cord connects to standard wall outlets. Buyers needing more than 40 watts or a different connector type should look elsewhere.
