Download Project Document/Synopsis

Power banks are one of the need to have product these days. But even power banks need charging. For that one needs to get the power bank charged in a power plug. This is not always possible when travelling so here we design a smart solar powered folding power bank.
The solar power bank integrates solar charging with efficient battery support and wireless charging to provide a multi functional unique power bank product. The device is able to self charge anywhere during day time so that he user never runs out of power.

This Wireless charging solar power bank provides the following advantages:

Easy Wireless Charging for compatible phones
Solar Self Charging
Foldable Design for Portability
20000maH battery backup
Added USB Type Charging port availability

The smart solar power bank integrates lithium battery pack with solar panels battery protection and wireless charging coils using dc power boosters and charge controllers to provide for a feature packed power bank.

This solar panels are used with charge controllers to charge the battery pack using charging circuitry. The powerbank makes use of LED for indication of current battery capacity. AN Adapter can also be used to directly charge the powerbank using AC power if needed.

The battery pack power is used to power the induction coil that is mounted on the top of the power bank. When mobile phone is placed over the top of the power bank an electromagnetic induction effect induces electric current in the coil mounted in the phone back. This is used to charge the phone wirelessly.
