Purpose and compatibility

This 65 W AC adapter delivers 19 V at 3.42 A through a 4.0 x 1.7 mm barrel connector. It replaces Chicony part numbers A18-065N3A and A065R191P and includes a detachable power cord with EU, US, UK or AU plug options. The unit accepts 100-240 V input at 50-60 Hz and carries CE certification.

Who it suits and who it does not

It suits owners of laptops that require exactly 19 V 3.42 A from a 4.0 x 1.7 mm tip. Buyers whose devices need a different voltage, current, plug diameter or centre-pin configuration should look elsewhere. The adapter is not suitable for USB-C charging or for systems that draw more than 65 W.

Capacity and headroom

The 65 W rating comfortably powers mainstream ultrabooks and thin-and-light notebooks during typical workloads and battery charging. Under sustained heavy loads that push the system beyond 65 W, the adapter will reach its limit and may throttle or shut down. It provides no headroom for high-performance gaming or workstation laptops.

Questions about this item

Which laptops accept the 4.0x1.7 mm barrel plug and 19 V 3.42 A output from this adapter?

Any laptop whose original charger matches part numbers A18-065N3A or A065R191P and requires a 4.0x1.7 mm tip with 19 V 3.42 A 65 W output will work.

Can I keep my older power cord if it has a different plug type than the EU/US/UK/AU cord supplied?

Yes, the adapter accepts 100-240 V 50-60 Hz input, so any IEC C7 or C5 cord rated for your local mains will work with the same brick.

How do I verify the adapter is delivering 65 W after I connect it?

The laptop should show a charging indicator and report 19 V 3.42 A in its power or battery settings while under load.
