Designed & engineered in California, USA, Jeda has been creating charging solutions for Model 3, and now Y for over three years. This hub is for Model 3's made before June 2020, with two USB A sockets to plug it into.

But it also provides a discreet location for your sentry/dashcam drive, which if the worst happens, might be very useful.
