45W AC Adapter for Asus Laptops

This 45W AC adapter delivers 19V at 2.37A through a 4.0mm*1.2mm connector. It accepts a universal 100-240V input at 50/60 Hz for worldwide use. The unit carries CE, FCC and RoHS certifications with multiple safety protections. The package includes the power adapter and an AC power cord.

Suits owners of listed Asus models needing

It fits devices such as the Q405U, Q302L, UX360C, X542UA and C202SA among others shown in the compatibility list. Buyers whose laptop requires a different voltage, amperage or tip size should look at another adapter. Users needing a higher wattage output for larger notebooks will not be served by this 45W unit.

Connector tip size is the critical fit factor

The barrel connector measures 4.0mm outer diameter by 1.2mm inner diameter. Verify that the original charger uses this exact tip before purchasing. A mismatched tip will prevent a secure connection even if the voltage and wattage match.

Questions about this item

How do I connect the 4.0mm*1.2mm tip and avoid the polarity mistake?

Match the 19V 2.37A output label on the adapter to the laptop's requirement, insert the 4.0mm*1.2mm barrel fully until it seats, then plug the AC cord into 100-240V mains; reversing tip polarity is the common error.

Which parts will need replacement after extended use?

The detachable AC power cable and the barrel tip see the most wear; the adapter body includes overcurrent, overvoltage, overload, temperature and short-circuit protection but has no user-serviceable parts inside.

At what point does the 45W limit throttle sustained charging?

When the laptop draws the full 45W continuously, the adapter operates at its rated ceiling; thermal protection will reduce output if internal temperature rises beyond safe limits during prolonged maximum load.
