AULA S75 Pro vs MCHOSE K99 V2: your questions
The MCHOSE K99 V2 has a significantly larger 8000mAh battery compared to the 4000mAh battery in the AULA S75 Pro. According to MCHOSE, this provides up to 69 hours of use with RGB on, or much longer with it off.
No, the AULA S75 Pro uses a 75% layout with 80 keys. This layout omits the numpad and some function keys to save space, but retains dedicated arrow keys.
