Important Notes Before Purchase

• Check the connector size: Make sure your laptop charging port measures 4.0 mm × 1.7 mm, rather than the rectangular USB-style connector or a Type-C port.
• Match the voltage and current: Your device must require 20V and no more than 3.25A. A 65W charger can power a device requiring 45W/2.25A when the connector size matches, but the reverse is not recommended.
