This laptop ac adapter is rigorously tested, meets or exceeds original laptop ac adapter's specifications, brand new with 1 year warranty. Our AC Adapter has ±1V Voltage allowance.

1. Before ordering this replacement ac adapter, you MUST check your laptop's input voltage and your original ac adapter's output voltage. Laptops with 18V-20V input voltage can use our ac adapter which has 19V output voltage; Laptops with 15V-17V input voltage can use our ac adapter which has 16V output voltage; Remember: never exceed ±1V tolerance. Using wrong output voltage adatper will damage your laptop.
2. You can calculate your original ac adapter's output Wattage [W] by multiplying the Ouput Voltage [V] by output current [Amps] i.e 19V X 4.74A = 90 Watts. You can choose a replacement ac adapter which has higher Amps than your original ac adapter's; but you can not choose an ac adapter which has lower Amps than your original ac adapter's because it can not provide sufficient power to your laptop. Adapters with higher Amps will not damage your laptop. The adapter's output current (Amps) and output power (watts) are maximum load ratings. Computers only draw as many amperes or watts as they need.
3. Please carefully check the plug tip's size of the adapter to make sure it can fit into your computer. First of all, please make sure that your original adapter's part number and your laptop's model number are listed below.
