I didn't see any post about this so hopefully not making a duplicate post here. Anyways I own a Camry Hybrid nothing wrong with it, except its small. So I been looking into hybrid SUV and not too much is jumping out at me until the Rav4 Prime was announced. So definitely looking into the Plug-in SUVs. My question is it cheaper to let it slowly charge or regular household outlet, or would it be cheaper to charge if I had one of the level 2 chargers? Thank you.
