Power supply shipped with a product

[blueskull]

Hi, a quick question to the knowledgeable people here having designed and manufactured digital gadgets.
I have a digital device designed, which uses ~20W of power, and is designed to power a type C laptop in the meantime, and I plan to allow up to 60W output power to type C. Therefore, it needs at most 80W input.

The question is, how can I ship a power adapter with it? I don't have budget to design and certify a custom made PSU, so I want to use an off the shelf power adapter.
However, since for ITE PSUs, its electromagnetic compatibility is certified with its user product, so if I grab an off the shelf PSU, the FCC/CE label will be voided if I use it with my gadget, not the computer it was designed to work with, is that correct?

In my case, I plan to ship my gadget with a 90W type C adapter (Dell LA90PM170 with different IEC C8 plugs for different mains sockets). I can certify my gadget with that PSU model, but in case that PSU goes out of production, do I have to spend another $10000 to re-certify it? Recertification can be very expensive since my design has a custom intentional radiator on it, and I don't want to do it twice.
Is there anyway to dodge this stupid certification rule?

I find this a strange rule as well because how about other equipment connected to a device? Do you have to certify each combination?
I think what you need to look out for it that the kind of certification for the power supply should match the certification of your device. You can also opt to sell as two separate items.

Can one even find specific certification reports? Just because Dell marketese describes it as a power supply for many of its laptops doesn't mean they didn't certify it for USB-C power delivery in general. Your entire question may be a non-issue.

In my experience: don't ship the PSU if you are on a budget or do not have the reach and pockets of a true multinational company. Send a leaflet with a clearly specified power supply and where to buy some models that meet the specs.
This will save you heaps of money in re-certification in case the PSU is discontinued.

(edit) also, you would be hard pressed to find a PSU that fulfills the entire globe FCC, IC, EU are the low hanging fruits, but CCC, KC, Anatel and others are much harder to cover
