Lenovo IdeaPad 100S-14IBR 45W Charger

Lenovo IdeaPad 100S-14IBR 45W Charger

The Lenovo IdeaPad 100S-14IBR 45W Charger is intended for compatible IdeaPad 100S-14IBR systems that require Lenovo's 45W round-tip AC adapter. It delivers 20V at 2.25A, which equals 45W, and uses a 4.0 x 1.7mm barrel connector. Those three details should all be checked before ordering because a matching-looking plug does not by itself confirm the correct charger.

Charging problem? Start with the power label

If a Lenovo laptop charges slowly, does not recognize an adapter, or has a damaged power brick, the first step is to compare the original adapter specification. For this listing, the required class is 45W, 20V, 2.25A. The IdeaPad 100S 14-inch platform is documented with a 45W AC adapter; compatible replacement listings use 20V 2.25A with a 4.0 x 1.7mm tip.

Check the underside model label as well as the text printed on the existing charger. This is especially useful for Lenovo product families that were sold in multiple hardware configurations, where another version of the same family may use a higher-wattage adapter.

Designed around the correct connection

The 4.0 x 1.7mm round tip provides the physical connection for supported models, while the 20V output matches the laptop's expected power input. Once the model, wattage, voltage, and connector are confirmed, the adapter can serve as a clean replacement for daily charging at home, work, or study.
