Portable charger for Nexus 6P

[longtime44]

Hello,
I don't really know what to look for in a power bank but I need something that won't damage my phone. I know there was an issue with wall chargers and certain cords that were damaging the 6P and 5X. I need a power bank now to bring to work and was wondering if anyone had a legit power bank that has the proper output for the 6P. I've tried to do my own research but lm not sure what I'm looking for. Thank you in advance!

The power bank shouldn't cause any issues--it's the cable. As long as you have the original cable, or one that has been approved by Google's Benson Leung (https://plus.google.com/collection/s0Inv), you should be fine.
