You can absolutely plug in to a normal outlet; the EUV comes with a level 1/2 charger - you just change the pigtail depending on what you're hooking up to. I just got my Qmerit installation today, and I was charged off L1 for the past several weeks, though I don't drive daily!

I personally purchased several accessories, most on Amazon - here's what I got:

• Central console tray (this is a form-fitting drop-in to help make that space more usable)
• AirMan ResQ Tire Repair Kit (this is supposed to be an unbranded version of the one you can buy from GM, but at a much lower cost.)
• Rubbermaid Roughneck 10-gallon storage bins (you can fit 2 side-by-side in the sub-trunk, with room left over for the charger. I keep emergency supplies in these that I don't want rolling around, and I can remove them, even in the rain, should I need to use the space.
• Floor mats (I got the Bolt EUV floor liners - the molded ones.)

I'm loving how quiet and quick my EUV is - so I hope you enjoy yours, too!
