I use it when staying at a hotel, and the charger is not right there. Worked perfectly in Natick and Worcester when hotel was about half-mile or so away (yes, I could have walked and did before I got the scooter. Second accessory purchase - first was the book "Tesla Model S – Best Car Ever!". My wife asked if I considered a Tesla hat instead.
I keep it in the underneath part of the trunk.
Also have a folding bike which I bring when I can, but it takes up a lot of room. Even if the scooter is in the trunk, it takes much less space than the bike.
