Can you use any laptop charger?
The connector tip, polarity and voltage should match the original charger. However, the alternative is to use a universal laptop charger. Universal laptop chargers ship with a variety of tips that will invariably include tips compatible with the most popular PC brands including: Acer, Asus, Dell, HP, Lenovo, Sony & Toshiba. Therefore it is highly recommended you do not use a charger that is not compatible with your PC.
