I am indistinct with Amps measurements and its use to power supplies with the conforming power cords that is plugged directly to the outlets. I owned an external hard disk that needs 12V 4.0amp adaptor. I placed a small block to control the hard disk power correctly. I have other cord that plugs with the outlet and can manage 2.5amps as specified on the tag of the wire. I want to know if this one will work on my hard disk or not. Please send me some suggestions and resolution. Thanks.
Amp measurement on External Hard Disk
I do not think a 2.5 amp code will be able to power a 4.0 amp adaptor, for the power that it will be transmitting will be tremendously too low. You will need to get a code that is exactly 4.0 amps which can be able to generate the 12 volts of power that are required to power the system, or you may get an amp adaptor that is slightly higher than 4.0 for it will be able to power the system too. But that may be a risk, in case you get an amp adaptor that is more that 4.0 amps, make sure that it is not way far from 4.0 for it will generate much heat that end blowing up your system, and therefore causing much damage.
