Yocan UNI Pro Version 2.0 has Type-C charging, metal construction, larger battery and more voltage options. It is my personal favorite 510 Cart device replacing ALL of my other 510 batteries and pen-style batteries.
UNI Pro version 1.0 has most of the same features except for the following:
- Plastic housing and construction (Weight savings!)
- Micro-USB charging
- Less voltage choices
