Sometimes it’s most convenient to charge at the home of your friends or families when visiting, however, this can come across as a little rude sometimes, especially if you expect it and/or there is an issue.
A common approach that works well is to ask ahead of time and offer to pay for the electricity upfront (often £5-£10 is more than enough), failing that a nice bottle of wine normally does the job.
That said the best thing to do is a have a backup plan in place so if it’s awkward / not possible then you can forget it and charge elsewhere afterwards or before you arrive.
DO NOT USE NORMAL HOME EXTENSION CABLES AS THEY CAN OVERHEAT. ALWAYS UNWIND ALL CABLES FULLY UNLESS YOU WANT A MELTED CABLE OR WORSE, A FIRE!
If you find yourself stuck with the only option of using a cheap extension cable then turn down the AMPS to 5 and keep checking the plug and cable aren’t getting too hot, most of these aren’t designed for continual load and having a dedicated high-quality extension cable option is going to be vastly superior and safer.
All Tesla cars should come with a UMC or Mobile Connector this allows you to plug-in to a normal 3 pin 13amp socket, however with only 6 meters of cable it isn’t always possible to use it, this guide goes into how you should extend this and the best products to use.
Option 1 – Total cost £64 (giving 25M + 6M length)
The easiest method of charging away from home is to buy and use the following:
- 1 x 10M or 25M or similar length industrial extension cable (NOTE: Paid Supporters can get this discounted by visiting the supporter discount page).
- A DriBox 330 IP55 Weatherproof Box
- & use your existing Tesla UMC / Mobile Connector (the small portable charger that comes with the car.)
This cable combination gives you a decent length of cable that should work in 95% of situations, worst case you have to leave a small side window open to feed the cable into a back lobby / utility room / bathroom etc.
Option 2 – More expensive but far more versatile – Total cost £350+ (Giving 2-25M + 6M Length + various options for power)
This connects to the Tesla UMC and provides you an additional length of cable with the MAXIMUM amount of power and versatility.
Even better, the compact version allows you to go through things like letter boxes etc for easy access to home charging, the rest of the system also allows you to basically charge at any location in Europe with the various connections.
Option 3 – Stick with what you’ve got and risk it (6 Meters)
If they’ve got an outside power socket this will be fine, or if you can park near to a window again this should be fine. The whole point of the Tesla UMC is that you’ve got a UNIVERSAL connector that will plug into any 3-pin socket as standard but some owners find the 6 Meter cable simply isn’t long enough for most occasions which is why some form of extension cable is worthwhile.
Option 4 – Get your friends/family to install a Type 2 wall box on their house
OK, so this isn’t something everyone is going to jump at the chance of doing for you but if it’s a families house that you visit often this is well worth doing.
