1. The battery life is so long that it can't stop.

Today's smart phones should be charged once a day under normal use; Even if the battery capacity is large, it can last for two days at most. Therefore, products such as mobile power supply have a broad market.

Compared with mobile phones and tablets, the battery life of kindle is ridiculously long. According to official data, the latest kindle kpw2 can be fully charged in 4 hours after being connected to the computer, and it can work continuously for eight weeks on a single charge. Many users report that if they read for two hours every day, the kindle pkw2 can't be charged for at least 10 days, and the power is still strong. Although the battery life of the old kindle3 used by Bian Xiao is far less than that of the new kpw, it is usually charged only once every half month in Bian Xiao, and sometimes it has mp3 playback function. It can be seen that the endurance of the kindle is by no means comparable to that of a mobile phone.
