Depending on what Tesla have in stock, it seems that most of the new cars now come with a 4.5m type 2 Mennekes, this might be perfectly fine, but I found on more than one occasion I needed a longer cable to be able to reach a charger at work.
There are lots of options available in both length and also if the cable can accept 3 phase or not. The type 2 cables that come with your Tesla are 3 phase, enabling you to charge faster when you can connect to the 3 phase charger.
Buying an additional cable
For 3 phase, I’d recommend sticking with Mennekes and of all the places you might think to check, BP Chargemaster seem to have the fairest prices on these.
The whole range of Mennekes cables from BP Chargemaster, including 1 phase.
Of course you don’t need a 3 phase cable, it just limits your charging speed if you are lucky enough to encounter a 3 phase charger.
Don’t forget to get your self a charging cable bag to save storing a dirty old cable in the frunk / boot!
