1. Low power delivery

The most frequent reason causing your Lectron Tesla to j1772 adapter not to charge your EV is its low power delivery.

The cause of low power delivery to your EV could be that your adopter is of low amperes. Your j1772 adopter should be of at least 40amps to provide enough power delivery to charge your car using an EV using a Tesla charger.


To fix this problem you have to make sure that your adopter is of 40amps at least. If you have bought an adopter of 38amps or lower, you need to return it and buy a new one of at least 40amps.

2. Start your EV

There is some sort of trick that can be used to start the charging using the j1772 adaptor using a Tesla charger. 

To make your EV start charging, you just need to ignite your EV when you have got a warning of “Charging Failed” from your EV.

This will start charging and when you turn your EV off, it will keep charging.

3. Accumulation of dust or debris

You may face issues with the adapter connection being sporadic or inconsistent. As a result, your Tesla charging may be interrupted or proceed more slowly.


You should also check your j1772 adaptor for any accumulation of dirt or debris and your EV’s charging port. If you find any, you should clean it with a soft and dry cloth and a gentle brush.

It is best to use a vacuum cleaner to remove the dust and debris. Additionally, you should also check and clean the Tesla charger. 

4. Overheating

Overheating is another reason that can cause your j1772 adaptor not to charge your EV. 

If you are using your 40amps  j1772 adaptor for a long time, it can be overheated and can cause your adapter to stop charging your EV.


The best solution to fix this overheating is to get yourself an adopter greater than 40amps. we recommend you to get an adapter of at least 60amps. So that it won’t be overheated and can continuously charge your EV.

5. Loose  connection

If your EV is not being charged use a j1772 adaptor with a Tesla wall charger. It is quite possible that there is a loose connection.

It is possible that the j1772 adaptor has not been properly attached to the Tesla charger or the j1772 adaptor has not been attached to your EV.


You should ensure that your j1772 adaptor is properly connected to the Tesla charger and your EV. You should try a little bit of force to connect the adaptor properly.

6. Wear and Tear or water damage

If your j1772 adaptor has fallen recently or it has been through any kind of accident, it is possible it has been damaged and has stopped working. 

Or if it has been exposed to rain or water, it will also stop working. Because it does not have any waterproof seal to stop water from getting in.


If you suspect any kind of wear and tear or water drops over or inside your j1772 adaptor, you may need to get yourself a new Lectron j1772 adaptor.
