As small as a thumb:Compact and convenient for hand carrying,so you can easily pack it in with you when you go out.
GaN technology for large energy:The full form of Gan is gallium nitride,which is a new type of semiconductor material.It has the characteristics such as large forbidden band width high thermal conductivity,high temperature resistance,radiation resistance,acid and alkali resistance,high strength and high hardness,etc.
Support by new gan technology to realize smaller size and higher power for fast charging of mobile phones and laptops at the same time.
