I have same Macbook pro 2016 type with yours, and I bought a portable battery in China. The battery has 2 Type-A port for output charging, 1 Type-C port for both output and input charging. That Type-c port could be use for charging MBP2016(without touch bar), with maxmium power up to 40W , voltage ranging from 5V to 20V that will suit laptop or mobile phone automatically to limit amp in case of damaging devices. Total available capacity may be 12000 mAh or 20000 mAh, which I'm not quite sure. Because when I looking it in the advertisement, it is named 'ZMI 20000 portable battery No. 10'. But the details on the back of battery shows with very little words '12000 mAh'.
