We've got a 2017 Volt and a Kia Niro PHEV sharing one garage, and between the two of them our actual daily miles are low enough that a full overnight top-off on regular 120V is plenty — neither of us drives far enough to need anything faster. Problem is the garage only has the one 20A GFCI outlet that makes sense for charging, so for about the last four months we've had both OEM charging cords plugged into a splitter/adapter thing we found that turns one outlet into two, and just leave both cars connected overnight.
It's been fine as far as we can tell, no tripped breaker, no complaints. But my husband mentioned last week that the splitter itself feels warm to the touch when he goes out to unplug in the morning, which is the first time either of us really stopped to think about whether this is actually a reasonable setup or something we've just been lucky with. Is this genuinely dangerous, or normal enough not to worry about? Open to better setup ideas if this is as bad as it sounds.
