This is an excellent charging adapter for my needs. Installation is pretty simple: Connect the adapter to the SAE J1772 charger, then connect to your Tesla vehicle. You can charge your car everywhere with this adapter since it is compatible with both Level 1 and Level 2 charging stations, greatly increasing the number of charging destinations for your Tesla. It works beautifully and is very robust!
This is a very well-constructed adapter with tight-fitting end pieces. Clicks into place with the original power cord without issues. The charging adapter is small and portable which can be stored at the back of your trunk so you can bring it with you wherever you go. There has never been a charging incident where it did not fully seat on the first try and give us a reliable charge.
