I'm the type that doesn't like to keep something plugged in if I won't be using it for hours or days. I have an Echo Show for my assistant needs so I don't need an always active Siri speaker. I love the Homepod but also like to be able to move it around. My office, my garage, the living room, etc. I noticed something that concerns me for long term use. Almost every time I plug in the Homepod, I see sparks coming from the outlet, no matter which outlet. Has this happened to anyone else? Is it a concern? I can always swap for another one if so.
