Replacement AC adapter for IdeaPad S10-423135U

This 20 V 2 A 40 W unit supplies the exact voltage and current the Lenovo IdeaPad S10-423135U expects. It replaces a lost or failed original charger so the laptop can charge and run simultaneously. The package includes the adapter and a detachable power cord.

Upgrade from damaged or missing original charger

Swapping in this adapter is worth it when the original brick no longer delivers stable 20 V output or the cable has frayed. It restores full charging speed without requiring a higher-wattage model. Buyers who need a second unit for travel or a dock should note this is a single-adapter package.

Steady 40 W output under continuous load

The adapter maintains its rated 40 W during prolonged charging sessions thanks to a 100–240 V 50–60 Hz input range and built-in protection circuits. The 5.5 mm × 2.5 mm barrel connector seats firmly to prevent intermittent contact. It is not suited for devices that require more than 2 A at 20 V.
