It was $5.99 from Kogan Black Friday Sales. In reality, it was actually $29.95 MSRP from other places. *Edit - Currently OOS
However the grey colour version is in stock at the time of the update - $3.99
Edit - Update About MFi Certification:
However, Kogan did not specify what model number is it.
Based on the pictures and the model Kogan has provided, it should be ZDC2LK3-BK from Zendure - $20.99 (Was 34.99)
I did a check through MFi Licensee App. It has a record of registration on it. 857348008805.
