This one has worked for me for years. Aukey CC-S1 4.8A Dual Port USB Car Charger - Black https://www.amazon.com/dp/B00M6QODH2/ref=cm_sw_r_cp_apip_Ut4qrOc9jao1U
I use these in my car to get USB charging: https://www.amazon.com/gp/product/B00M6QODH2/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
The latest comment with the Amazon.com links was apparently deleted by the project founders.

At least 3000 backers didn't see this coming.
Just copied it from the title:
I bougth this and it's amazing http://www.amazon.com/gp/product/B00M6QODH2?psc=1&redirect=true&ref_=oh_aui_search_detailpage No coil but just buy the cable size you want.
And yes, I'm aware it's says it's not compatible but it is.
If you're in a car frequently, I'd recommend the Aukey Car Charger. I know it's not a powerbank, and you have to use a USB-A to USB-C cable, but it's the closest thing I've found to the rapid charger due to it's high amperage. Really fast!
So long as the Female USB end is being used as an output, I think it should probably be fine, but I'm not entirely clear on the setup so I can't promise anything.
What are you trying to do? As an overview?
Plug into the cigarette lighter and wire to a more convenient flush-mount location? Are you trying to get 2 USB-A outs? Why not use a cigarette lighter adapter with 2 USB-A outputs in place of the anker instead of usb-c -> usb-a?
