Last month, the power adapter to my router died out of nowhere. I wasted a ton of time troubleshooting literally everything else other than the power adapter because I've never had one die before the actual device itself.
Of course none of the other adapters I had on hand fit. I had to order a new one...
I've had that situation a few times.
Just cut off the end and soldered it to another power adapter of appropriate voltage/amperage/pinning (be especially watchful in case one is centerpin positive and the others centerpin negative)
That feels like something I probably could do... But under no circumstances should do.
Should I spend the next hour or two soldering something I will always have anxiety over being a fire hazard, or should I spend $3.97 on amazon to have it here the next day. ¯\(ツ)/¯
With a soldering iron and another supply with the same voltage and amperage, anything is possible.
Seems like a fire hazard
Not if you wrap the wires with enough electrical tape to cover a football field
You'd be absolutely wrong, the adapter is on the low voltage side probably between 5-12v DC Even if you shorted it you'd just blow the transformer.
It's also extremely easy to do...
Things are easy to do when you know how to do them.
Its also easy to learn how to do
There's always a first time for learning something new. So go ahead and try it on something small and inconsequential when the opportunity presents itself.
Just need to know the basics of electricity and how it goes where. Many wires are colour coded too, so there's even less to worry about.
Seems like you're guessing
I mean, if you want to solder your own power adapter and don’t have any fear of producing something that could present a fire risk and put your home and family in danger, knock yourself out.
I am ok buying one online for $10. I also don’t have time to solder my own power adapters to save $10.
I wouldn't recommend an inexperienced person mess with AC voltage but a 5-12V DC power adapter with a couple Amps max is a long way from dangerous and it's not a fire hazard either really
You're overestimating the skill required. Also, these connections are almost always "low-voltage", so the risks are easily mitigated.
