Using your Tesla

Power sockets: what you can run from a Tesla

A Tesla has a huge battery, so owners naturally ask what else it can power. In the UK the answer is: small things only.

What's in the car

  • USB-C ports for phones, tablets and laptops that charge by USB-C.
  • A 12V socket (the old "cigarette lighter" type) in the centre console or boot, depending on the model. Check your owner's manual for its maximum current; it is designed for small accessories.
  • No household (230V) socket on UK Model 3 and Model Y, and no vehicle-to-load (V2L) adapter.

What works

  • A 12V cool box or compressor fridge sized for car use.
  • Phone, tablet and laptop charging.
  • A small 12V tyre inflator.

What doesn't

  • Kettles, microwaves, toasters, hairdryers and anything with a heating element. These need far more power than a 12V socket can give.
  • Mains appliances through a cheap inverter plugged into the 12V socket, beyond very small loads.

Camping power

For more power, many owners use a portable power station (a large battery pack), charged at home or from the car's USB-C or 12V socket while driving. Combined with Camp Mode, the car keeps the cabin comfortable all night.

Does it drain the battery?

The 12V socket and USB ports may switch off when the car sleeps. Camp Mode keeps them on. Small accessories use very little of the main battery.
