Smartphones are a great invention, but a truly long- lasting battery is still a dream.
So my idea involves the integration of a power bank and a Wireless Power Receiver module FT1236M inside a normal woman’s purse (or a man’s one, of course), to always have a source of energy to charge your smartphone.
The charging of the power bank is obtained by placing the bag on a base that containes a Wireless Power Transmitter module FT1235M, powered by a common 5V 2A switching power supply.
You would also have more charging bases (at home, in the car, at office).
With the available energy you can also power some “courtesy lights” LED, in order to find objects in the dark.
It could also be possible to add a board to manage the lights automatically, accordingly to the environment’s brightness and a charge indicator to see if the bag is properly coupled with the base.
If the bag does not have a flat bottom, you can install the receiver coil to the side, ensuring the adherence with the transmitter using small magnets.
