Q&A
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.
