Are there any products that charge multiple batteries at once?

I have found several products that charge one extra battery at a time, but I have about 5 batteries, for long road trips to trade out while on the go. It would be nice if when I get to a hotel, I can charge all of them before I hit the hay, then in the morning, I have what is essentially 5 full charges for my phone. Any thoughts would be appreciated.

As far as I was aware of, they only charged 1 at a time.

You can get universal chargers for something around $5-$10, so you can buy a few and charge a few batteries at once.

There have to be multiple battery chargers - no manufacturer is going to have a few thousand individual chargers plugged in - but there probably aren't any available to the public.
