My magnasonic projector's battery doesn't last long enough
I need this projector to operate on an ac instead of dc. There are no instructables on this specific topic

I have not seen or touched this particular gizmo before, apart from looking at pictures of it on the web, and reading some of the text describing it.
However, I am guessing that if you run it with a USB cable plugged into it, with that USB cable connected to a 5 volt DC supply. Then that supply will give it as much power as it wants.
I am not sure how much current this gizmo will want while it is running, but it might be as large as, around 2 amperes. There is some official, upper limit, for current supplied by a USB cable. I mean, one that conforms to the official USB specification, and I think that limit is 2.0 amperes.
The attached picture, I stole from an eBay listing. This one:

That picture shows us where the USB port is, and its shape is "micro USB" which is pretty common. It might be the same shape as the port that charges your phone.
In fact, a generic, 5 VDC, phone charger supply, with a micro USB plug output, might be just what is needed to keep this projector juiced up while it is running.

Just get a power adapter (DC) with the same voltage as the combined batteries and hook it up...
