Shimano EC6000 Charger

I own one of these with a US plug on it that I bought 3 years ago on eBay and have never seen another since. I have 2 Shimano E8000 bikes now with one charger between them. Does anyone know where I can get one of these with the US plug, or if the EC6002 can accommodate the 110V input here in the US, as I have seen these available without the plug (SM BCC1) Thanks!
