    i would like to buy another home to type2 charging cable. Original cable has a bulk of electronic near the end of the car. Everu ebay cable is only cable and has no bulk in between. Would it work or could i damage the car with aftermarket cable?
    Thanx

    I couldn't find the everu cord you are talking about.

    That said, I think you're trying to find an EVSE that's just a cable, and doesn't have the inline "bulk of electronic" that makes it an EVSE.

    That "bulk of electronic" near the wall outlet end of an EVSE is kinda important. It's what makes the end you plug into the car electrically dead until it is fully connected and the car starts requesting power. That prevents arcing during connection, and prevents any shock hazard handling the cable while it is disconnected. That arcing bit is kinda important for plugin hybrids, best to avoid sparks anywhere near gasoline.

    AmazingE seems to be one of the smaller EVSE's out there, as is TurboCord.

    Its funny that they did not instal this bulk inside if the car. Would be easyer on cable.

    It would be impossible to put it inside the car. The whole purpose is that there is a shutoff circuit in the cable. You can pick up the car end of a J1722 cable and stick a metal fork in it, or drop it in a puddle, and nothing is going to happen except maybe damaging the connector. These safety features are for when the cord isn't connected to a car, and for while it is being connected.

    J1722 isn't just an extension cord. The cord is electrically dead except for a low voltage (12v) pilot signal until the cable is connected to the car. Once connected, resistance applied to the pilot triggers the circuits in the "bulk" to turn on the power in the cable. (That pilot signal is also set up to tell the car how many amps it can draw).

    If you notice, when you plug the OEM cable in to your car, a second or two later there's a click that comes from the "bulk". That's it turning the power on after being signaled that it is connected to a car.

    If those smarts were in the car, the cable would be live while you were plugging it in. There would be nothing the car could do to prevent arcing or you getting shocked while making the connection.

    The folks that designed J1722 were doing these things to make it safer than an extension cord. They thought about ways to make it so you don't get shocked, even if you are handling the cable in a downpour. Even in a garage, the socket on your car might be a bit wet after pulling in out of the rain, and water is still running off the side of your car. It is a good idea to keep it all dry, but there are safety features there to reduce risk of shock and sparks.

    That said, there's still quite a lot of the circuitry needed that *is* in your car. An EVSE doesn't have any smarts related to controlling the charge of the battery, doing voltage conversions, etc. That's all in your car. The EVSE just handles connecting/disconnecting the power, and telling the car how much it can pull.

    So lets say if i get cable without bulk, o could charge, but i risk spark and damage feom spark? That in mind, why would they produce this cable without bulk? Did it pass some kind of quality test?

    Are you talking about the handle portion of the cable (#1 and #2 part in the diagram) or SSID on the cable (#5 in the diagram)? AFAIK the handle near the car has no electronic in it but IDK for sure.

    I don't know what the cord you are describing looks like. Does it not have the handle portion or CCID? Could you post a photo or link?

    There's a *LOT* of cables out there that have passed effectively no tests. Most of the cheap ones sold on Amazon/ebay aren't UL or ETL listed and haven't been tested by anyone except maybe whatever tests the overseas manufacturer came up with.

    Some will even claim to be UL listed despite being only made with some UL recognized components, usually the cable and J1722 connector. But that leaves the entire control unit as being untested.

    In the absurd extreme, someone found an ebay listing where someone stuck a J1722 connector on a belkin power strip. Remember kids, there aren't many rules when it comes to listing something on ebay.

    If you want a cable that's been tested, make sure you buy one that's got the listing to prove it, and check the listing number to make sure it isn't just for the cable assembly.

    That said, my guess is the OP actually saw a listing for a J1722 cable. Just a cable, meant for repairing a damaged EVSE or building your own EVSE.

    It's a replacement part so you can just replace that part and not have to buy a whole new EVSE. Kind of like being able to replace a tire without having to replace the whole car.

    I went to Amazon.de and claimed I lived in Croatia, here is a EVSE charge cable with a European 230 volt plug.

    www.amazon.de/dp/B07HRLXJLD

    It is adjustable 16 Amp/ 10 Amp so not to overload your household wireing.

    Well my car has AMPs charging setting so no need for cable to have it.

    Toyota here sells origial carging cabke for the same price. Around 200euros. I was hoppeing to get better price on Amazon.

    Toyota's will be better quality than anything on Amazon.

    Did you click my link in post #2?

    @JimboPalmer is right that the OEM one from Toyota would have the best quality. Also the highest price, but that's to be expected.
