Good Guys now have this reduced to $135 and then using the code above get a further 30% off (applies to all Cygnett accessories).
Details in the old thread but this power bank is distinguished by Power Delivery at 45 watts (will power many USB C laptops) plus USB C and QuickCharge 3.
Don't forget CR for extra 2.5%, every bit counts :-)
