Not only will it charge 4 batteries at the same time, it will deep cycle them better than any other method.
It turned up on eBay. I have not seen any on there since. I was skeptical, as the seller listed it as New in Box, but $60 less than direct. It did indeed arrive brand new, never used, sealed in box. I take chances often on eBay under the protection of the buyer protection plan. If you buy something and it is less than described, or even if it never comes, you get a full refund.
Anyway, here is where they are currently available: SmartPowerCharge.com Site Product Detail Page
