                  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 plug-in, 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.


                  Aluminum alloy shell material, fire-proof and anti-fall; Surface anodizing technology, anti-abrasive and safe to use.

                  Portable Spot Welding Machine is mainly used in the welding of nickel sheet of cylindrical battery like 18650.

                  Built-in high-rate polymer power cell, the maximum output current is up to 639A, and it can continuously weld thousands of points after being fully charged.

                  With output power and remaining power indication, there are two output modes: timing trigger output and automatic trigger output. At the same time can set 4 output power.

                  Has four dual-color indicator lights, Green light for indicating the power, red light for indicating the welding power.

                  Charging indicator light: red for charging, green for fully charged.

                  It will automatically shut-down after ten minutes of no use.

                  Compact size and light weight, easy and convenient to carry.
