One possible glitch on Lazada purchased Kindles I ran into. My new Kindle Paperwhite 6.7 inch model purchased on Lazada stopped charging after a months use. I tried every online suggestion there was, nothing worked. I decided I must have somehow damaged the USB-C port. I bought another one, also from Lazada and the exact same thing happened, after a months use, stopped charging. I was totally flummoxed. There is no Kindle service available in Thailand and they can't be mailed to the US because of the built-in battery.
A friend was going to the US for a visit so I gave them to him to take there and drop off at a Kindle service center near his home. Just on impulse, he tried charging them at his home and amazingly, thy both charged right-up without issue. WTF???
Some deeper research revealed that most Kindles sold in Asia originate with Kindle-Japan. Japan has a weird power grid, half the country is 50 cycle, half 60 cycle. This creates a lot of conflicts and compromises in circuit design and though I have no proof, I think that was somehow involved with my battery charging issue. The only way I can consistently charge them is by using a power bank as the source. Then they charge without issue. If I use a charger and outlet, sometimes they charge, sometimes not.
