Kindle is especially suitable for reading novels and English books, and the experience is super powerful. It can be said that the damage to the eyes is very low, and it is not tired after watching for a long time. Standby feels good, too Personally recommend KPW3, the Japanese version is only over 600. I asked if the Japanese version could be used in China, and the answer was yes. Amazon is also rich in resources, but the kindle doesn't support PDF books.

The original kindle system supports azw, pdf, mobi, prc and txt formats. Among them, mobi, azw and prc formats are the best. If you scan a PDF, the display will be unclear because it is not tailored to 6 inches, or it will be unclear because the scanning effect itself is not good. If the word is too small, the original system can consider local amplification, and the intelligent pruning function can be used under the system. Txt format support is not very good, there may be garbled or page turning problems. It would be better to save the txt format encoding as UTF-8 encoding (open a txt file in your computer and click File → Save as → Select UTF-8 encoding → Save), but it is recommended to convert it to mobi.
