Ac wall adapter - Meade Universal AC Wall Adapter for ETX-PE & AT, LS, LT, LXD, LX90, LX200 (up to 14"), RCX/MAX and MAX

I use my telescope outdoors. I also use it a good distance from the grid, on camping or road trips. Needless to say, I was disappointed to see that the adapter is for indoor use only. Point is, I doubt it will hold up in the great outdoors for as long as I would like. Really would like to see a better, more rugged version that has some protection from moisture, dust, and the elements in general.
Otherwise, this is a basic indoor adapter from 120V AC to 12V, 5 A DC. So if you can find a cheaper but reliable one elsewhere, might not be a bad idea.
No problems with this one so far.
