@Junket ahh, my bad. It's for Kindle 8th gen. Kindle Basic touch (KT3)
And apparently, living in Asia, anything I buy from the US/UK online merchants the shipping + custom charges make the equipment triple the amount of it's original price. Unfortunately, it'll also take several days to arrive here.
I tried the local market but they had nothing for 1.8v and even the online merchants here sold the 3.3v or 5v devices. Needless to say, I already tried my options. And then, I'm also not keen on spending $30 on a $80 device.
Either ways, as far my understanding of devices to, and I could search online. I think I already found my solution. But was wondering if anyone else could shed some light on it perhaps.

That cleared up my own doubts somewhat. I guess, the rest is just trial and error unless someone gives an assured answer to it.
Also I'm not sure if KT3 uses a 3.3v or 1.8v input.
