Style two(Base on One and improve)
1. Wireless charging is not work on this power bank. Follow is the reasons: A. Wireless charging will bring high heat to the small power bank and it will harm the PCB and lithium battery as well, our engineer said. B. Wireless charging chip and PCB is too costly, it will add over 3USD on this project and we do not know it will work for charging power bank, it needs to test and verify. C. Wireless charging coil is too small and the charging current is below 200mA, and the battery is 1000mAh, it needs more than 5 hrs to charge the power bank fully. We think it is too longer time than Micro-USB cable(it only one hour to charge the power bank fully by cable)
2. But we can use one stand to solve wireless charge method. Follow is the idea: A. Customize one stand, like the photo style. B. Customize PCB to charge power bank and JUUL. C. The charging method is the same as JUUL’S way. D. Customized the top of stand, one is for JUUL and one is for power bank, the charging pins are the same as JUUL charging two pins.Thus we can offer two options to buyers. F. Then we have three items for the market, buyer can choose what they can afford or they prefer. One is the only power bank case, one is the only charging base, one is power bank case and charging case.
