Hi, i personally use a Voltage Converter Plate, that works well:
 https://www.globalmediapro.com/dp/A2HG93/Globalmediapro-VLP-U-V-Mount-to-DC-Multi-Voltage-Converter/
 https://forum.krontech.ca/index.php?topic=564.msg3856#msg3856
 .
 I found, that it works best if i leave the Internal Battery of the Chronos in the Camera, that way i can Change V-Mount Batteries at need and also avoid the Camera just Switching off Randomly (which can Happen Sometimes, if the Voltage is not Stable enough, or the Voltage Converter has Trouble keeping up with the Current the Camera Needs).
 What you linked sure is an interesting Option, and should in work in Theory, given it provides 19,5V at 3A, but only if the Polarity of the Barrel Jack is Correct, which i could not confirm from the Amazon Listing, maybe check on that with a Voltmeter or something, if you have trouble to run the Chronos off of it. Given Polarity of that Small Converter Cable is Correct, and the Converter Cable is not Broken, i see no reason, why that Should not work?

Can the camera Chronos 2.1-HD power receiver handle 3A current? panasonic fx9 19.5v 40-60w 3A
Original camera Chronos 2.1-HD power supply 19v 45w 2.1A
Is it possible to check amps (current 2.1A → 3A)?

Amperes (What is indicated as [...]A ) cant be too much on the Side of a Power supply. It works about like this: Voltage needs to be within the Limits the Camera can Handle, which in the Case of the Chronos Cameras is between 17 and 20 Volts, where 19 and 19,5V are both well within. The Thing about Current in Amperes is, that the Camera basically Takes as much as it needs. As Long as the Power Supply can Provide at least 40Watt of Power. Watt is just Voltage, which is Fixed by the Power supply, in the Case of the one you have 19,5V; multiplied by Current, which in this case will be 2,05A to make 40 Watt. The Power Cable You have is able to provide up to 3 Ampere of current, so based on That it would be able to provide up to 58,5Watt of Power to the Camera, which is probably needed for the Panasonic Cameras it is meant to power.
 Imagine a car that can Drive 240kmh, that does not mean you need to drive it that fast, or that it will just drive that speed no matter what at all times. Means just that is the Limit, and it will usually not go much faster than that in most Situation.
 .
 Most important, apart from the Fact, that the Voltage is within the Limits the camera needs, which is the Case here, the Powersupply can Provide more Power than the Camera needs, which is also the Case, AND Polarity!
 .
 For the Polarity, do you have any other Power Supply for the Panasonic Cameras this is originally meant for? I cant find any information regards Polarity on these Cameras anywhere, and from this information i assume you would also not be able to figure out if it is correct on your own.
 A Image of the Label on one of the Original Power supplies for the FX6 or FX9 would help a ton to confirm what Polarity that adapter cable ist (no Product page for any of those mentions anything about it also).

Just figured out, that its actually a Sony Camera, this Adapter is for, there is no Panasonic FX 6 or 9...
 Thats why i found nothing at all, but even when looking for the Sony, i just cant figure out any actually official Information regards Polarity.
 The Documentation on that is just Exceptionally bad, not only for all the Third-Party Power Supplies and Adapter Cables, but also from Sony itself.
 Needed to actually look on YT in hope of Finding some Video that would hopefully show some Angle of the Camera with high enough Resolution to be able to read the Polarity off that Cover for the Power Supply Connector there.
 Looks like Positive Tip to me, Screenshot Attached.

 .
 Not only that there is never any Info about the Polarity, apart from on that Cover Plastic, i also couldnt find anything confirming its actually the Same Size as the 5,5/2.5mm Barrel jack as the Chronos.
 Polarity should be Correct based on that Screenshot.
 .
 Can you take a Image of the Barrel Jack of the Adapter Cable and the Original Power Brick / Wall Power Supply that came With the Chronos right next to each other, with the hole of the Barrel Jack facing the Camera, to see if the Size is the Same?

Not exactly the question here, but for those looking for an alternative to power up the camera away from outlets, I've been using a Jackery 300 battery for a while now.. I keep the power supply connected, as far as mobility, I carry the battery in my backpack when using the camera handheld.

Can you order this Adapter Plate, if the GlobalMedia-Pro Adapter does not Ship to your Place?:
