What is the difference between Akko v1 and v2 version?

Akko v2 version has some advantages shown as below:

1)  Detachable USB-Type C cable from the keyboard (this is the KEY INDICATOR). 

2) Updated firmware for some media features.  

3) Improved stabilizers to prevent larger keys from wobbling. 

Note Akko 3087 isn’t specifically being categorized between v1 and v2. The “V2” design only applies for the 3108 model.
