Q: What is the difference between the Upgrade 1S and the previous 1?


A: 1S has added the function of adding your idle automatic discharge, which can automatically discharge to 50% in 5 days and extend the battery life. 1S also optimizes the circuit layout and structure, with better performance. In addition, type C charging port version is added to 1S.


Q: What is the difference between type C and micro USB?

A: Type C version uses type C charging port, supports positive and negative plugging, and distributes a type C charging line. In addition, the type C circuit uses the gold deposition process, which is more durable.


Q: Does type C support fast charging?

A: Considering that fast charging may affect battery life, it only takes about 2 hours to charge from 50% to 100%, so fast charging is not supported.
