135W Replacement Adapter

This iTekiro AC adapter delivers 20V at 6.75A for 135W output. It is built for Lenovo IdeaPad L340 and S740-15IRH models listed in the compatibility data. The unit includes a UL-listed 6 ft AC cord and a 6 ft DC cord for extended reach. It suits users who need a direct replacement for a lost or damaged original charger.

Replaces 90W and 135W Units

The adapter replaces original Lenovo 90W and 135W chargers for the supported laptops. It does not replace 170W or 230W power supplies required by higher-spec machines. The upgrade is worth it when your current adapter has failed or when you want a spare with long cables. Buyers needing 170W or 230W output must look elsewhere.

Fits Supported IdeaPad Models

The connector and voltage match the listed L340 and S740-15IRH part numbers such as 81LK and 81NW series. The 6 ft DC cable frees placement options without extra extension cords. A durable case resists water and humidity for steady operation. The adapter requires a grounded AC outlet and the correct laptop input jack.
