Genuine 135 W Chicony Adapter

This genuine Chicony A16-135P1A AC adapter delivers 20 V at 6.75 A for a total of 135 W. It accepts a worldwide 100-240 V input at 1.5 A and 50-60 Hz. The unit ships with a 5.5 mm by 2.5 mm barrel connector and includes a power cord. It is manufactured by Chicony Electronics, a supplier to major laptop brands.

For Thunderbolt 3 Dock Users

This adapter is built as the original power supply for the Belkin Thunderbolt 3 Dock Plus Dual-4K Docking K39105NA. Buyers needing a replacement for that specific dock will find the correct voltage, amperage and connector fit. Builders powering a different laptop or a dock with a higher wattage requirement or a different connector size should look elsewhere.

5.5 mm × 2.5 mm Barrel Connector

The single specification that determines compatibility is the 5.5 mm outer diameter and 2.5 mm inner diameter barrel plug. Only devices designed for this exact connector and the 20 V 6.75 A output will work safely with this adapter.

Questions about this item

What connector size fits the 5.5mm by 2.5mm barrel on this 135W Chicony adapter?

The adapter terminates in a 5.5mm outer and 2.5mm inner diameter barrel plug that mates with the Belkin Thunderbolt 3 Dock Plus K39105NA power input.

How do I connect the included power cord to the adapter body for the first time?

Plug the IEC C13 end of the supplied cord firmly into the recessed inlet on the adapter until it clicks, then connect the mains plug to a 100-240V 50-60Hz outlet.

When should I replace the detachable mains cord that ships with this 20V 6.75A unit?

Replace the cord if the insulation is cracked, the plug pins are bent, or the connection becomes intermittent at either the wall socket or the adapter inlet.
