Usage & Installation Tips:
Before purchasing, check your laptop’s original adapter label or the bottom/back of the laptop for required voltage & current, and the connector size/type.
This adapter is 5V 4A output; using an adapter with a lower current may cause slow charging or prevent full device performance. Conversely, using a much higher voltage adapter on a device rated for 5 V may damage it.
Ensure the connector size is 3.5 × 1.35 mm and polarity matches (commonly centre positive for Lenovo barrel types).
Use on a stable surface and ensure the adapter has airflow—do not cover it with cloth or place it on soft surfaces while in use.
Unplug the adapter when not in use for extended periods, and avoid exposing to liquids or extreme heat.
If your laptop has USB-C charging or a different voltage requirement, this model may not be suitable—choose based on your device’s specification.

For users of Lenovo IdeaPad 100S, Miix 310, or other models with 5V 4A input, this Original Genuine Lenovo IdeaPad 20W 5V 4A Laptop Adapter from LaptopVai offers a smart, reliable replacement or spare option.
