A perfect car for getting around Portland. Charging stations are ubiquitous around Portland, so charging is not generally an issue. Chargers can be located with apps like Plug Share or Charge Point. Since you can plan on 240 miles on a full charge, you may not even need to plug it in.
Be advised that EV's do not travel as far when traveling at highway speeds. I would not advise planning more than 150 miles on a road trip without knowing where you will charge next.
The Bolt is guaranteed be charged to at least 200 miles at the time of rental, and you are welcome to return the car with as little as 20 miles of range remaining..
