This is probably the best 20 dollars I spent on a car charger! Works great, small form factor, and world’s smallest dual QC 3.0 charger. You get full Quick Charge 3.0 on two ports and is backward-compatible also with any QC 2.0 devices. This is the world’s smallest car charger that I have been able to find with simultaneous QC 3.0 charging. There are many other similar products but they are much bulkier and this one is a small as it gets.
