I am using kindle 5.

Kindle 5 does not have the National Bank, and the National Bank electronic paper book has only one model - kindle paperwhite

K5 has a good price/performance ratio , the general American version or Japanese version on Taobao, the price of the Japanese version is lower.

However, the K5 system does not have Chinese. You must either use the native English system or install the Duokan system.

In contrast, the Kindle Paperwhite's system has Chinese, is touch screen, can also turn on the backlight, and is very cost-effective.

You can learn more about this consultation and compare more to see which one you like better.

The advantage of National Bank is that it only has a warranty, but as long as you take good care of it, it is generally not that easy to break.

Businesses that sell well on Taobao basically have no credibility problems, so you can buy with confidence.
