This deal is back up and running. These things are amazing and will save you a lifetime's worth of NRMA membership fees.
These also work as a regular power bank with with USB A and USB C ports if ur caught in a jam.
You need to choose the 12000mAh option and then add the coupon SAFY20 or PLUSFY22.
FWIW it’s $97 delivered on AliExpress, so $66 for local stock and a good brand is an (Oz) bargain.
