This adapter is designed for Lenovo laptops that require a 20V 4.5A (90W) power supply. Common examples include many ThinkPad E, T, X series and older IdeaPad models that use the matching connector type. Always check your laptop’s label or manual to confirm it needs 20V 4.5A before buying.
⚠️ Important Notes
✔ Original vs. Third-party: Original Lenovo adapters typically have Lenovo branding and a model/part number printed on the label. Genuine ones often offer better reliability and safety.
✔ Connector Must Match: Even with the right voltage and amps, the plug shape must match your laptop’s charging port (USB slim tip vs. barrel).
✔ Universal Input: Works in most countries with proper mains plug adapters thanks to the wide 100–240 V input range.
