The product image is for reference only. The actual item you receive may differ slightly in appearance.
Please note: the size of the adapter varies depending on the wattage — higher wattage adapters typically have a larger power brick due to increased power capacity.
Check Your Laptop’s Power Requirement
You can find your laptop’s required wattage in one of three places:
On your current adapter (look for 20V + Amp rating)
On a label under your laptop
In the technical specifications from Lenovo Support
Example:
If your laptop says:
20V – 3.25A → 20 × 3.25 = 65W
So, you need a 65W or higher adapter.
⚡Higher Amperage Is Safe
Using a power adapter with higher amperage (A) is completely safe — as long as the voltage (20V) and connector type (square tip) match your laptop.
Your laptop will only draw the amount of current it needs
For example, if your laptop requires 20V 3.25A (65W), you can safely use a 20V 4.5A (90W) adapter.
The extra amperage is simply available if needed, but it won’t be forced into the laptop or cause any damage.
âś… Higher amperage = Safe
❌ Lower voltage or wrong connector = Not safe
âť— Important Notes
Connector: Must be the square yellow tip
Voltage: All adapters listed here are 20V (compatible)
Amperage : Match or go higher — never go lower
Quality: Use genuine or high-quality replacements to avoid damage
