Frequently Asked Questions
What does this cable do exactly?
This is a J1772 extension cable — it extends the reach between your Level 2 J1772 charging station and your EV by 16.4 ft (5M). The male J1772 plug connects to your charging station outlet, and the female J1772 socket connects to your vehicle’s existing J1772 charge cable. It does not convert between connector types.
Can I use this with my Tesla?
Yes — if your Tesla uses a J1772 adapter to connect to Level 2 stations, this extension cable works seamlessly. For Tesla vehicles with NACS ports, you’ll still need your J1772-to-NACS adapter in addition to this cable.
Why is there an Orange color option?
The Orange version improves cable visibility in low-light garage environments, making it easier to spot and avoid tripping hazards. It’s a popular choice for busy garages or shared charging setups.
Is it safe to use outdoors in rain?
Yes — the IP55 rating protects against dust and water jets from any direction, making it suitable for outdoor use in rain. The cable also maintains flexibility down to -30°C for reliable cold-weather use.
What’s covered under warranty?
All Tesstudio charging products come with a 1-year manufacturer warranty against defects. Contact our support team for any issues.
