I'm not vouching for this specific product, but based on your description there is a 240v outlet that they plug directly into (as opposed to an installed charging station)--is this something you're looking for?
There was a post here that said the included charging cable that comes with the clarity is actually rated for and capable of 240v despite being a 120v connector, and then some electrical engineering mumbo jumbo about how you can convert it, but I have no idea how difficult that is for a novice.
I just picked up a used Clarity w/o a charger. Bought this one on amazon, charges at a solid 15 amps ~1750 watts per the Kill-A-Watt on 120v.
