Thanks for your concern for the newly released PIQ 2.0 products. Sorry for the late response. We are consulting our concerning departments for the questions you mentioned for more accurate and detailed answers. Your patience is much appreciated.
Regarding your concern about the difference between the PowerCore Speed series and the PIQ 2.0 series, please kindly be noted that the PCBA of PIQ 2.0 series are indeed lighter and smaller than the PowerCore Speed series. In this condition, for better product experience, we made some improvements on the inner structure and upgraded the indicators to the circled type, which both cost space. Thus the final size and weight of the PIQ 2.0 are almost the same as PowerCore Speed series.
Except for those improvements, the PIQ 2.0 series are released at a cheaper price after being stocked. Meanwhile, the PIQ 2.0 series have a ridged texture(except for the PowerCore Slim that was designed earlier), which offers one more option for customers who do not like the feeling of the materials of the PowerCore Speed series.
Hope we've made it clear. Should there be further concerns, please feel free to contact Anker via "firstname.lastname@example.org" for more details.
Have a great day!
