The eBay vendor seller from Las Vegas, says that he will put on either a 25 or 35 foot cable and whatever plug type you want if you buy from his website. That seems great!
I notice many complains for that Duosida charger on Amazon about tight fit of the cable to the car. One observer noted that the car receiver sockets seem to taper while the cable pins do not. If you have the Prius Prime, does this problem show up with your cable?
It is a tight fit but nothing a little jiggling can't handle. Even my wife who's 5'1" can unplug the charger without any issues. Nexus 6P ?
