Asus Laptop Chargers

Do all Asus laptops take the same charger?

No, not all Asus laptops take the same charger. Chargers vary depending on your specific Asus laptop model. They do differ significantly in voltage (e.g., 19V vs. 20V), wattage (e.g., 45W, 65W, or 240W+) as well as connector type (barrel plug vs. USB-C).

Asus Laptop Chargers

To find the correct charger for an ASUS laptop, you must identify the specific model, as different models require unique connector shapes, voltages and wattages. Flip your laptop over or check the original power brick. Locate the Output listing (e.g., 19V ⎓ 3.42A). Calculate wattage by multiplying volts by amps (e.g., 19V × 3.42A = 65W). Your replacement charger must match the original voltage exactly and its wattage must be equal to or higher than the original.

Asus Laptop Chargers: A Guide to Compatibility

1. Match the Wattage

• 45W – 65W: Suitable for standard Asus laptops like VivoBook and ZenBook.
• 90W – 120W: Designed for thinner Asus gaming and creator models.
• 150W – 330W: Required for heavy-duty Asus ROG (Republic of Gamers) laptops.

Important: A higher-wattage charger can be used safely. Using a lower-wattage charger than required may damage the battery or cause the laptop to run slowly.

2. Verify the Output Voltage

Ensure the replacement charger’s output voltage (V) matches your original. Common voltages are 19V, 19.5V, or 20V (for USB-C models).

3. Check the Connector Tip

Using the wrong plug size can physically damage the charging port. Asus uses several types:

• USB-C: Common on modern ultra-portables (ZenBook, Vivobook, ExpertBook).
• Proprietary Barrel Tips: Sizes range from tiny (2.5 × 0.7mm) to larger (5.5 × 2.5mm).
• Gaming/Square Tips: ROG models often use specialized 4-hole or large rectangular plugs.
