$IINX The increase in total revenues due to acquisition of Fangguan Electronics was partially offset by the decreases of $815,210 related to the existing business (excluding Fangguan Electronics) for the three months ended December 31, 2019 compared to 2018. After Fangguan Electronics was acquired, all business of Fangguan Photoelectric was replaced by Fangguan Electronics, which caused total revenues to decrease by $1,041,165 for the three months ended December 31, 2019. In addition, the decreases were also the result of a decline in sales of portable power banks (the ever-primary produce of the Company before the acquisition) of $182,103 for the three months ended December 31, 2019, which is expected to be offset by increases in average sales prices as the Company increased emphasis on higher margin goods for these existing business (excluding Fangguan Electronics).
