The EVANNEX Mini Sound-Activated USB Disco Ball lets you turn your EV's cabin into a mini dance floor in seconds. It plugs directly into a USB port, senses the beat of your music, and projects multi-color strobe lights across the interior. This guide covers where to place it, which Tesla models it fits, and important safety notes you should know before using it.
Product at a Glance
- Mini Sound-Activated USB Disco Ball for EV Owners: The Mini Sound-Activated USB Disco Ball is a half sphere approximately 1.4" (37 mm) in diameter at the base and weighs 15 g. Its compact size means it fits easily in a cup holder or rear seat area without taking up passenger space.
Mini Sound-Activated USB Disco Ball for EV Owners - Mini Sound-Activated USB Disco Ball for EV Owners: It draws 4W at 5V and uses low-power LEDs. The projector can generate seven color combinations from red, green, and blue LED sources. The power draw is negligible for an EV battery, so you can enjoy the light show without worrying about range impact.
- Mini Sound-Activated USB Disco Ball for EV Owners: Comes with a USB-C adapter for Model Y. Fits USB ports in Model 3, Model S, Model X, and Model Y. You can use it in most current Tesla models without extra adapters, though CyberTruck compatibility is not yet confirmed.
Setting Up the Disco Ball
The disco ball requires no tools or permanent installation. Follow these steps for a quick setup.
- Choose your location: The rear seat area is ideal because the male USB connector is built into the base — no cable needed. For front seat use, you may need a USB cable (not included) depending on the connection type.
- Plug into a USB port: Insert the disco ball directly into a rear USB port. For Model 3, the two rear USB ports are spaced far enough apart to accommodate two disco balls side by side for a more intense effect. For Models S and X, only one disco ball can fit due to port spacing.
- Turn up the music: The disco ball's circuitry senses the beat when audio volume is sufficiently high. Multi-color lights will then dance across your interior surfaces that have a line of sight to the ball.
Safety and Usage Warnings
The disco ball produces strobing lights that may trigger seizures in people with photosensitive epilepsy. It should not be used if you or any passenger has this condition or is otherwise sensitive to strobing effects. Additionally, use the disco ball only while the vehicle is stationary to avoid driver distraction.
What the Instructions Don't Cover
The supplied information does not specify exact battery drain over time, but the 4W draw is very low. There is no mention of using the disco ball with non-Tesla EVs, though it uses a standard USB-A connection. For front seat installation, you will need to supply your own USB cable — the product does not include one.
