For those that really need something small, the Anker PD Nano and PowerPort III Nano are on sale at BestBuy and Amazon (links above).
While both are 18w USB-C chargers, the PowerPort III is probably the best option for both iOS PD devices and Android QC3 devices since it does PD as well as Qualcomm’s Quick Charge 3.0 (what Anker calls PowerIQ 3.0).
However, if you only have iOS devices, the PD version may be best since the PD version supports 5V 3A and 9V 2A output (which is slightly better than the PowerPort III which supports 5V 2.4A and 9V 2A). Watts=V*Amps.
The QC 3.0 (and now QC 4.0) versus PD fast charging standards are confusing but here is a decent article to help make sense of it all:
