Well, it seems like the power adaptors of D-Link products are more or less the same. I flipped through the power adaptors of my dlink products and found that I have a smaller two pin power adaptor rated at 12V/2A! The power brick of DNS-313 outputs at 12V/3A but the size isn’t really good for lugging it around to my friend’s house.
Slimmer power adaptor to bring around with DNS-313
Rated at 12V/2A
As mentioned earlier, the original power brick outputs at 12V/3A while this one outputs at 12V/2A. Plugged in the smaller power adaptor and crossed my fingers while the DNS-313 boots up.
Hurray! It seems like it has got no problem with it. Been running it for around 2 hours now, transferring files to and fro the DNS-313.
