Frequently Asked Questions
What does this cable do?
This is a NACS to NACS extension cord. It plugs between your Tesla wall connector or Mobile Connector and your vehicle’s charging port, adding an extra 5M (16.4 ft) of reach — useful when your charger is mounted far from where you park.
Will it slow down my charging speed?
No — as long as you select the correct amperage rating that matches your wall connector output, there is no reduction in charging speed. Choose 48A for maximum-output setups.
Does the button on the cable open my Tesla’s charge port?
No — the button on this extension cable does not control the charge port door on your Tesla. Open the charge port via your Tesla app, touchscreen, or by pressing the charge port door directly.
Is it compatible with Superchargers?
No — this extension cord is for AC Level 2 charging only (Wall Connectors, Destination Chargers, Mobile Connectors). It is not compatible with Tesla Superchargers.
