How can I confirm a replacement laptop adapter will work with my laptop?
Match the output voltage exactly, then confirm the connector type/size and polarity. Wattage can be the same or higher than your original adapter.
Where do I find the voltage and wattage information?
Check the label on your original charger (or the laptop’s bottom label). Look for Output (V) and Wattage (W). The voltage must match exactly.
Can I use an adapter with a different voltage?
In most cases, no. Using the wrong voltage can cause charging issues or damage your laptop.
Can I use a higher wattage adapter (for example 90W instead of 65W)?
Yes—higher wattage is usually OK as long as the voltage matches and the connector fits. Your laptop will only draw the power it needs.
How do I confirm the connector size is correct?
Compare the tip with your original charger and check the listed connector size (OD × ID). Even small differences (like 5.5×2.1mm vs 5.5×2.5mm) may not fit properly.
What does polarity mean, and why does it matter?
Polarity indicates which part of the plug is positive/negative. It must match your original adapter for safe and reliable charging.
My laptop uses USB-C charging. Can I use any USB-C charger?
Not always. Your laptop may require USB-C Power Delivery (PD) and a minimum wattage (such as 45W/65W/90W). Use a PD charger that meets or exceeds your laptop’s requirement.
Can this adapter be used internationally?
Many adapters support 100–240V input. Check your charger label. If it supports 100–240V, you can use it overseas with the correct plug adapter.
How can I find my laptop model on a Windows laptop?
If you are using a Windows laptop, you can find your laptop model using System Information:

• Step 1: Press Windows + R to open the Run window.
• Step 2: Type msinfo32 and click OK.
• Step 3: In the System Summary section, find System Model in the right pane.

Choosing the correct replacement adapter matters for safety and charging performance. Use this checklist before you place your order:

1. Match the Output Voltage

  • Check your original charger label for Output (for example, 19V).
  • The output voltage should match exactly.

2. Confirm Wattage / Amperage

  • Wattage can be the same or higher than your original adapter.
  • Using higher wattage is usually fine if voltage and connector match.

3. Check Connector Type & Size

  • For barrel tips, match the connector size (OD × ID).
  • For USB-C, ensure it supports USB-C PD and enough wattage for laptops.

4. Verify Polarity

  • Match the polarity symbol shown on your original adapter label.
