We have a 20amp level one plug and it works great for that. The electrician installed the plug and the charger. He said the charger was fine and it’s worked flawlessly daily for 4 months. The adjustability of the amps is really great. We leave the VW one in the trunk. We’ve only used it like you mentioned- at the in laws for a top off overnight as we’re unfamiliar with their charging options there (they’re pretty terrible so glad we had it). As of right now we have no need for level 2 and aren’t getting that installed anytime soon.

My charger does this.
