Hello This project is about wireless recharging. But not the usual way using the charging pad etc... What I want to do is to be able to transfer battery from one mobile to another. Suppose one smartphone has no battery and another smartphone is fully charged, when bringing both phones together, I want a system, using induction current etc..., to make the phone with the battery to start charging the one with no battery. Which means, it will be DC to DC. Note: It does not have to charge the other phone to its maximum level. Only 5% will be ok, but it needs to recharge as fast as when you connect it to a AC power supply. You can use whatever system you want, but it has to do all the specifics above. Thanks!

Greetings, The idea you have is certainly amazing. However it requires research to even figure out whether its doable with current technology. Wireless charging works on the concept of magnetic or capacitive coupling and that required AC voltage. Since you want to charge DC-DC, we have to generate AC from the source phone so that it can couple its energy to the destination phone. That is where the research is required - whether it can be done by using some part of the phone itself or will it require an external accessory requires detailed study of the possibilities. I am offering you to do this feasibility study to see if this idea is worth pursuing further with the currently available technology. Look forward to hear from you. T & R Alok Pugalia

Good Day, I have read the description and eager to know more about the project. With your details it seems the other phone without the battery will be working with the power of the other phone that has fully functional battery. If this is the logic and if you wanna add more, I think I can help you with it as I am already working on wireless charging device. But you have to be patient, as my whole work will be theoretically. But I can ensure you a great deal that it will be working fine. Eagerly waiting for your reply. Hope to meet you soon. Regards, Arnab Ganguly
