The Amazon Kindle Paperwhite uses a USB 2.0 charging cable. This cable allows users to charge the device by plugging it into most computer USB ports. The end of the charging cable that plugs into the Kindle Paperwhite uses a Micro-USB connector. This is a standard connector for small devices.
The Amazon Kindle Paperwhite does not come with a wall charger; only the USB cable. The Kindle Paperwhite reaches a full charge after about four hours of being plugged into a computer. Amazon does sell an adapter for customers who would like to charge their Kindle Paperwhites from wall outlets, as well as a higher-capacity wall adapter for faster charging.
