Wow, you must be ready to take a long trip! Feel free to use the charging cards located in the glove compartment to recharge the vehicle when the vehicle begins to run out of juice. If the vehicle has really low battery at the beginning of your trip such as 10 miles or less, please contact Green Commuter. We strive to make sure that our vehicles are recharged sufficiently between reservations. We suggest you check out Plugshare app. to map out charging locations before you head on long journeys.
