EV rentals bring a few extra planning considerations.
Charging infrastructure varies enormously by country and even by region within a country, so researching charger availability along your specific planned route matters more with an EV than with a gas rental. Charging time also needs to be factored into your schedule in a way it simply doesn't with a quick gas station stop.
Ask the rental company about the charging cable and adapter included, since plug types differ by region and you don't want to discover a mismatch after you've already left the lot.
