Lenovo charger & battery categories
No—Lenovo laptops do not all use the same charger. Differences come from connector type (USB-C vs Slim Tip vs round) and wattage requirements (45W vs 65W vs 90W+).
Why the same charger may not work
- Wrong connector doesn’t fit.
- Lower wattage can cause slow charging or no charging under load.
- Some devices require USB-C Power Delivery profiles that cheap chargers may not support.
How to match the correct Lenovo charger
- Identify the connector type (USB-C / Slim Tip / round).
- Read the charger label for wattage and output specs.
- Match your laptop model family (ThinkPad/IdeaPad/Yoga/Legion/ThinkBook) and power needs.
When this looks like a battery problem
If your Lenovo drains while plugged in or charges extremely slowly, the charger may be underpowered. Confirm wattage before replacing the battery.
