Before you buy
Can I use a higher-watt charger?+
Yes — as long as the connector is the same (USB-C Power Delivery), a higher-wattage charger is completely safe. Your laptop only draws the power it needs, so a 65W or higher charger will charge it normally (often a little faster).
Can I use a lower-watt charger?+
Not recommended. Below 65W 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 65W or higher.
Will this damage my laptop?+
No. USB-C Power Delivery negotiates the correct voltage automatically, so there is no risk of over-volting. A correctly matched connector and sufficient wattage cannot damage your laptop.
Can I use USB-C instead?+
Yes — this laptop charges over USB-C. Any quality USB-C Power Delivery charger rated 65W or higher will work.
