Tips

Before ordering, verify that your laptop's original adapter has the same output voltage (18.5V) and connector size (7.4mm x 5.0mm). The smart pin communicates with the laptop to ensure correct charging, so this adapter is not suitable for laptops requiring a different voltage or connector. For travel, pair with a suitable plug adapter for the destination country.
