Tethered vs Untethered Charging - What's the difference?

When buying an EV charger you have a few choices to make.  One of those choices is to go tethered or untethered.  What does that mean?  Well a tethered charger has the charge cable permanently attached to the charge station and therefore is quick and easy to plug in.  An untethered charge station on the other hand means you can plug in a Type 1 or Type 2 charge cable depending on the vehicle you need to charge.  One however is much faster and much less labour intensive than the other.
