Best Answer
USB-C alone allows 4.5 Watts ( 900 mA @ 5 V ) and thunderbolt 3 improves on that greatly.
According to Apple:
Thunderbolt Source: https://support.apple.com/en-us/HT207256 USB Source: https://support.apple.com/en-us/HT201163
The above specs are the same for the 2017 MacBook Pro models. The MacBook models only have USB levels of power and data available.
