April2 2018: If chargers can be made wireless by Qi technology, why not powerbanks? 
Hong Kong based Toreto recently brought its Wireless power bank, Zest Pro to  India.
This is a 10,000 mAh Lithium-Polymer   battery that   lets you charge your Qi-enabled  phones or tablets by just placing them on the power bank.
At the asking price of Rs 2999 ( same as the Belkin charger),  I can see  it making sense to those who currently don't have a Qi-ready phone but may get one in future, because it sports  two of the usual USB charging ports as well. 
A nice cross over device!
