it will 'work', but not particularly well.
from your description it sounds like it's 20w maximum per port, versus
40w combined if one port is unused (which some chargers can do).
20w would be sufficient to slowly charge the battery while the macbook
is sleeping, but not enough for when the macbook is being used, which
means the battery will slowly drain, although not as fast as it would
have had there been no charger.
get something with more power. even 40w is on the lighter side.
