Replacement AC Adapter for Lenovo IdeaPad S10e

This 100–240 VAC 50/60 Hz adapter replaces the original charger for Lenovo IdeaPad S10e models 4187-2PU and 4187-2QU. It delivers the same voltage and connector fit so the laptop charges exactly as designed. The 10 ft power cord gives generous reach from wall socket to desk. Built-in over-current, over-voltage, short-circuit and total-power protection guards the notebook during every charge cycle.

Upgrade from a Damaged or Lost Original Charger

When the factory adapter fails, frays or goes missing, this unit restores full charging capability without modification. The jump is worth it if the original brick no longer holds a secure connection or shows melted insulation. FCC, CE and RoHS certifications confirm the replacement meets the same safety baseline as the OEM part. It is not for users who need a higher-wattage brick for a larger laptop or a multi-voltage travel kit with interchangeable tips.

Limits of a Fixed-Output Barrel Connector

The adapter supplies a single fixed voltage through a proprietary barrel plug, so it cannot charge devices that require USB-C Power Delivery or a different pin layout. The 10 ft cable length is fixed and cannot be shortened or extended without adding resistance. Continuous operation at the upper end of the 100–240 VAC range relies on adequate ventilation around the brick. Buyers who need simultaneous laptop and phone charging from one brick should look elsewhere.

Questions about this item

What plug style does the WAWEIS adapter use for the Lenovo IdeaPad S10e 4187-2PU?

The adapter is built to match the original barrel connector on the S10e 4187-2PU, so it fits the laptop's DC-in jack without an extra tip.

How do I install the 10 ft power cord, and what step do people miss?

Plug the IEC C7 end into the adapter brick, then the wall plug into a 100-240 VAC outlet; the step often missed is seating the C7 connector fully until it clicks.

When should I replace the 12 month warranty adapter or its cord?

Replace the unit if the brick overheats, the cord shows exposed wire, or the laptop stops charging while the LED remains off.
