FAQ (Frequently Asked Questions)

1. Q: My laptop’s original charger was 45W. Is this 65W version safe?
   A: The 19V output is identical, and the laptop will only draw the current it needs. A 65W charger will run cooler and last longer.
2. Q: How do I know if I have a 3.0×1.1mm or 5.5×1.7mm port?
   A: The 3.0mm port is very small, similar to a headphone jack. The 5.5mm is much larger and thicker. This model is the Small Tip (3.0mm)
3. Q: Is it compatible with the ASUS ZenBook UX31E?
   A: Yes, the UX21E and UX31E use this specific 3.0×1.1mm connector.
4. Q: Do you offer the Indian (Type D/M) plug?
   A: Yes, we can produce this model with the Indian Standard plug for your market.
5. Q: How does this 3.0×1.1mm connector differ from the standard Acer 5.5×1.7mm?
6. A: The 3.0×1.1mm is a “Fine Tip” designed for ultra-thin laptops (Ultrabooks). The 5.5×1.7mm is much thicker and used for standard, larger laptops. We recommend verifying the port diameter before bulk purchase.
7. Q: My original charger was 33W or 45W. Why should I buy the 65W version?
   A: Amperage (3.42A) is a “pull” technology. The laptop only takes what it needs. Using a 65W charger on a 45W laptop is actually a premium upgrade; the adapter will operate significantly below its thermal limit, extending its lifespan and providing a more stable voltage under heavy CPU loads.
8. Q: Is this compatible with Samsung 12V or 14V tablets?
   A: This is a dedicated 19V adapter. Connecting a 19V adapter to a 12V/14V device can damage the internal circuitry. Always match the Voltage (V) exactly.
9. Q: Does this adapter support the ASUS “Square Tip” 4.0×1.35mm?
   A: This model is the 3.0×1.1mm Fine Tip. While they look similar, the 4.0mm tip is slightly larger. HTJ offers a separate dedicated line for the ASUS 4.0×1.35mm series.
