I bought it off Amazon before the price increase about a month ago. Just looked now and it’s only $699.

Is this the kinda thing that I'm looking for? I know our utility company offers a rebate/partially pays for something from this company. Looking at the Juicebox you mentioned, it seems like a similar product.

I have zero doubt that we'll eventually have something that can take advantage of the charging ability of a more powerful unit than the Volt or Ioniq can handle at this time, so I don't mind going overboard at all. I'm not concerned with 100% future proofing as that simply not possible, but you can certainly plan for a reasonable future need, and I feel getting something that can handle a current Tesla Model 3 or older Model S (not the newest car), would be a great point to start.

I want to have all of our ducks in a row before we make any moves.

For a few dollars more...
