need something that will quick charge my S10+ and charge from Micro-USB.
I have a PowerCore 10000 PD and PowerPort+ Atom III and do not want to carry a larger USB-C charger this trip.
PowerCore+ 10050 Vs. PowerCore Speed 10000?
seem to be about the same?
Yes, and so is PowerCore II 10000, which I would recommend.
The S10+ is a USBC phone, so why would you want micro-usb?
I figured that out! haha. I need Micro-USB for a music player and camera.
Just carry those cable and charge the battery with USB-C cable.
Maybe cut it down with a multi cable, I think Anker does one with micro,c,lightning on one end and usual usb on the other.
You mean this one? Anker Powerline 3 in 1
