Pretty much accurate.
Converter is designed to reduce 220 AC or 120 AC power into 12 DC power.
The big deal with that is most 'Battery Chargers' only produce about 10 amps at best,
But a power converter is often called on to produce as much as 3,000 watts, or about 250 amps at 12 volts DC.
That's a BUNCH of amperage at a relatively low voltage.
Even little 300 Watt models are producing 25 amps constantly, and that's still more than most alternators average...
They are 'Over Grown' battery chargers, with a real attitude!
They get very hot, and have to be cooled.
Internal fans do the job, and normally when I see one that has 'Died' it's from the fan quitting, and if it's a better quality one, it will have a thermal fuse.
If it's a cheaper one, the fuse is the transformer melting down...
Lots of these that give up the job at hand only need a new thermal fuse, and I use a lot of computer fans to cool things. Cheaper, quieter and usually do just as good a job.
If you need a new one,
