The other day I noticed a device with an adapter that had wildly different amps and voltage but the Watts were the same and it fit so...

I think it goes there...

That is going to result either in a bang or nothing happening.

You can use a power supply if:

  1. the plug fits

  2. the polarity is correct ( - and + are at the correct location)

  3. the voltage matches

  4. the current and wattage is the same or higher

#4 is subtle. It might work with less current, but this is a caveat not appropriate for novices.

#3 is also sometimes not a problem, many devices work with a bit lower or higher voltage. It's because the DC to DC converter that is used to control the voltage for the device itself is tolerant enough.

Sometimes devices are multiple volts tolerant with the caviate that the components get warmer with higher input voltage and therefore the device could have reduced life expectency. If the devices where not tolerant especially for lower voltages a slightly bad cable or a long cable could drop the voltage enough so the device wouldn't function.

You want to make sure the Voltage matches or bad things can happen. The current and Wattage can be the same or higher, it will only draw as much as it needs.
