Shopppeeeee!
Well I'm in Shopee and Lazarda country (though not Malaysia). Used to live in Kajang though, best satay on the planet, I'm jealous.
Straight off the bat, the top electric kitchen gadgets would have to be cheap rice cookers/steamers and those plugin table top BBQ's with the wee soup bowl in the middle. As an expat, I'd suggest any images you use on your Shopee listings are in Malay and in English. Text only is easily translated, but so many Lazarda/Shopee vendors miss out massively on the expat buyers with no English text on images (which Chrome does not translate). This leads to clicking "back" and looking for another product with English info.
I would assume that a huge majority will be Malay, but most Brit's in the UK wouldn't know just how often we use Shoppee/Lazarda in SE Asia, Amazon is a dot on the landscape compared to these. So you will probably do well if you get the products right.
Good luck!
