Amazon has the Emigvela 20000mAh type C power bank on sale from $50 down to $20 via coupon code. Tax free since sold by 3rd party seller (fulfilled by amazon).
Coupon code: FN7FVVWK
**Appears that somehow the link didn't go specifically to the right seller where the code applies, so in the case it doesn't, seller BEIYIusHOME / fulfilled by amazon should be selected**
Has PD up to 45W via type-C. Note that single type-C port takes care of both input and output, so no simultaneous charge-through. For those unfamiliar, PD = "Power Delivery" charging standard, and supports charging macbooks, pc laptops, nintendo switches, etc that support higher current usb-c charging, thus not a simple conventional power bank for just 5v devices.
Also has type A 5v/2.4A out for everything else via usb type A. (i.e. NO QC)
Quick spec copied from Amazon:
type c supports:
5V / 3A
9V / 3A
12V / 3A
14.5V / 2.5A
20V / 2.25A
description says comes with 1 usb c to c cable, some reviews stated 2 (perhaps 2nd is type a), so YMMV
does NOT come with a wall brick charger. Advise using other PD type c chargers to recharge this bank, if using generic usb chargers normally for phones/tablets, via type-a to type-c, it will either charge real slow, or at worse as some review had found, even becomes a slow drain?
But yah just use a PD charger to charge this.
