So finally as an iPhone user I can take advantage of C. I have a PD plug, order the c-lightning, now I need an external battery with C out, and not too high capacity. I hear that Anker has a Slim version of this, the power core 10000 with PD https://www.amazon.com/Anker-PowerCore-10000mAh-Portable-Delivery/dp/B07HBTY3Z2/ref=sr_1_3?s=electronics&ie=UTF8&qid=1549503406&sr=1-3&keywords=Anker+PowerCore+10000+PD
I would rather wait for the slim version unless anyone has an opinion on something else…I found this

Any other ideas?
Thanks!!
