I would just like some advice since I melted a USB cable today

You don't need to be an engineer, don't need all the technical details
and power formulae. You just need to know that you bought a cheap,
off-brand charger that was made in a country that is infamous for
producing shoddy and dangerous electrical devices--like the surge
protector that I bought that had the hot and ground wires soldered to
the same terminal. Be glad that it melted the the USB connector and
didn't set your house afire and kill your family. And next time, don't
be penny wise and pound foolish; buy the manufacturer's original
charger for each device.

based on what he's posted, it's more likely to be a ****ty cable than a
****ty charger.

either way, he did cheap out.

.. sadly these days, price is not an indication of quality. Neither is a
brand name. Particularly since high and low priced, and "brand" and non brand
products are largely made in the same factory.

I seem to recall a time long ago when amps and speakers were advertised to have a power rating that was equivalent to a lightning strike hitting the power supply. I remember holding a speaker that weighed a few ounces that was advertised as being a 25 watt speaker. The label didn't show how many milliseconds the speaker would last at that power level. The same sort of exaggeration seems to be going on with a lot of Chinese made USB chargers and power supplies. （〇_ｏ）
