PIP arrives shortly. Trying to decide if it is worthwhile to buy a Level 2 charger plus installation. Convenience of fixed unit is an advantage. Keeping Toyota provided Level 1 solely as a backup/mobile unit is another. Time to charge is of some benefit but is not a huge issue since PIP recharges pretty quickly. Without garage, my installation would be outside. Can Toyota Level 1 charger be kept outside on a semi-permanent basis? Thoughts, Level 2 model recommendations.
