I had to back away for this option....
I have a lease and to replace this cord when i return the car will cost about $900!
Blink's equipment is about 599 with 100 back in station purchase.
You didn't read the FAQ at http://EVSEUpgrade.com
then. There are at least three ways to deal with the lease "issue".
1. Trade it with some other owner who has an unmodified one, but would like an upgrade. You can probably even get some of your upgrade money back in the swap. (my favorite)
2. Send it back to EVSEUpgrade to be downgraded again.
3. Replace the plug with a 5-15 like it originally came with, and turn it in with no one the wiser.
Some people have even turned in the modded unit, without doing anything to it. It's not a problem.
