Hardware How dangerous is this to use?

[SecureBoot]

So a few weeks ago, my ac adapter broke for unknown reasons. I just ordered a new 3rd party one so I decided to strip the rubber back just to see if the wire snapped or something similar. After stripping about 3 inches (8-9ish cm if I'm remembering the right conversion) from the middle and an inch (2.54 cm) from the usb-c end, I tried plugging it in just for kicks. To my shock, it worked perfectly. The problem is now I have exposed foil and I don't know if that could be potentially dangerous.

I'm most concerned about where my initial cut was (where you can see that fuzzy substance and a bit of wire). The other cut looks like this

Featuring my lovely dissection tools.

Would this be dangerous to actually use? What about if I cover it in electrical tape?

I would be more worried about the switch being damaged by a faulty cable. The dc current the power adapter outputs isn't enough to do any real harm. At most you may get a fun jolt.

Shrinking tubes would have been great, you can try to re-do it correctly, peeling the plastic on the copper cables, and twist/sold them, after that putting the shrinking tube would do the job.

Or buy a 3 USD charger..

How would it hurt the switch? I'm not technically inclined enough to know. The Switch has a feature that makes it disconnect from the TV when it doesn't get the correct voltage. I wonder if it would do the same thing.

I would, but I don't have a soldering iron... Or soldering experience.

Since the cables are big enough, you can use a dirty cheap solder iron, that are about 5 bucks, you can just twist them together, and apply the shrinking tube.

if it doesn't explode, the battery will degrade quickly because it will have an irregular charge with a random voltage and amperage

wouldn't use it on my switch

So you're saying no, I shouldn't use it.

What counts as an irregular charge? I ask because I'm pretty sure I have bad charging habits. This applies to my Switch and my phone. Sometimes I leave them charging overnight, sometimes I run them to 60% and then plug them in midday. Occasionally, I keep hovering within 20% of a certain charge throughout the day. Am I screwing up my devices by doing that?

Probably the cable it will still be defective and will send wrong information to the charger and the battery will be irregularly charged, even if it works

That's no problem with modern batteries. Letting it discharge fully is far worse for the battery. Actually if you never charge it fully and only charge it to 80-85%, and charge it as soon as you get the low battery warning or even before, it should increase the battery lifetime.
Also I recommend powering the Switch completely off when not using it since sleep mode drains the battery a lot and wastes battery life.

If you keep removing the charger and then charging and keep doing it all day long too much times times in a row it still affects battery and on Android they recommend from time to time to fully discharge and fully charge so that the phone can calibrate the battery.

My girlfriend damaged her crap cheap Samsung's battery in a year. My old Nokia N95 even in like 2014 was still holding enough charge to play music 4 more than half a day and would still keep it for around a week. I have always fully discharge and charge it and it worked 4 quite some years.

But the best is to charge when battery low warning appears and let it always go to 100% and like 1 time per month fully discharge and charge with the device OFF

duct/electrical tape it and it's fixed.

Your gut is saying don't do it I bet. I'd go with your gut. Rather, just wait playing your switch and getting a new one then not having one at all.

Get an original adapter, since the third party isn't up to "Nintendo standards" (Yes Nintendo can't do proper USB charging either....) Would I use this? Hmm no. I see the front of the USB and it looks melted or that someone chewed on it. I would avoid it at any cause.
