Just a technical question.
If you charge at home on your drive do the connections "lock in" to your car or can scallies come along and unplug them "just for a laugh"
Yes they lock onto the car. If you get a tethered lead, this is hard wired into the charger end. You can get Chargers with keys to turn off the power when not in use, so no one sneaks a quick charge. Sophisticated chargers have NFC or keycodes to limit access to authorised users.
Obviously best situation is inside a building or behind a gated drive
