3.7V lithium charge full 4.2V/ suitable for 18650 polymer etc
Smaller than the 18650 battery cross-section charging module, but also with discharge, is our carefully designed a replacement 4056 and other linear charging module. Compare 4056/4057 and other linear charging technologies. The charging temperature control of this module can be said to be off ten streets. The key point is that the length, width and height are only 16*12*4.4mm. Using Type-c port, you can input and output. The downside is that chips are expensive.
