This is one of a few chargers that is strong enough to charge the MacBook and 13" MBP. Just got mine and wanted to see if anyone else was experiencing:
1. Noise. When charging there is hissing/buzz which can also react to electrical noise caused by scrolling.
2. Cable issues. This one came with a USB-C cable (some others don't) and to see if the cable was causing the noise I tried an Apple one, but this won't charge. You can hold the button down as long as you like but the battery will only receive power from MBP, not give it.
Here is product page:

Quite disappointing. Being limited to one shortish cable for charging might be a deal breaker.
EDIT:
Seems it is only apple cables that don't work properly. Tried another C and can charge off it.
