Before you buy
Can I use a higher-watt charger?+
Yes — as long as the connector is the same (Lenovo slim-tip), a higher-wattage charger is completely safe. Your laptop only draws the power it needs, so a 230W or higher charger will charge it normally (often a little faster).
Can I use a lower-watt charger?+
Not recommended. Below 230W the charger may charge very slowly, only charge while the laptop is off, or fail to keep up under load — and the battery can still drain during heavy use. Stick to 230W or higher.
Will this damage my laptop?+
No. This charger delivers the exact 20V voltage your laptop expects, through the correct Lenovo slim-tip connector. A matched connector, voltage and wattage cannot damage your laptop.
Can I use USB-C instead?+
No — this Lenovo laptop uses a Lenovo slim-tip barrel connector and has no USB-C charging port, so a USB-C charger won't physically connect. Use the barrel charger shown above.
