I have a removable hard drive. Its power adapter's specification is

Flying Electronic factory
model: FLY36-5-12
S/N: W0408182331
input:100-240 Vac,2A,50/60 Hz
output: 5V 1.5A, 12V 1.5A

I found that the light on the adapter isn't lit upt when plug into the wall electricity outlet. I have used it for 7 years. So I guess it is dead?

I search on the internet. The closest to my adapter is this one

External Hard Drive AC / DC power adapter FLY36-5-12 (equiv)    
Input voltage: 100V ~ 240V
Output: 12V, 5 V 2A Up to Up to Watts

If I understand correctly, the two adapters have the same specifications, except that the outputs of the two adpaters are not the same (1.5 A versus 2A). So I wonder if I can purchase the second one to replace the first one?

Thanks!

Make sure the connectors are the same size and you should be ok. The ampage difference isn't too different... Can't promise anything though!

Most manufacturors will allow a slight difference, it's always safer to 'undervolt' and see if things work rather than supplying over, but that difference is only marginal.

  • Thanks! So overvolt is bad while overcurrent isn't?

    There will be no overcurrent, because the supply will provide only the current your device will need and nothing more :-)

Current output is actually "MAX CURRENT OUTPUT". If your appliance needs 1.5A at 12V, you can use a 200A 12V supply without problems (provided that connector and polarity matches)

  • Thanks! Do you mean the adapter will be able to output any current that is less than the "MAX CURRENT OUTPUT", depending on the my appliance's need?

  • Yes, precisely.
