Bub that is the only one I could find and they say the wattage
isn't what they say.
It is the only unit I've found though.
Now that I think about it, you may be better off going with a car stereo, reason is ... most of those will allow you to skip through your files on the USB drive. This Pyle is bare bones. Stick it in and it plays it from beginning to end.
Some of the new WiFi routers for your home have a USB port in the back of them, I have a Netgear and it's got one. You can plug in any USB drive to it, thumb, or USB-Hard Drive, and share the files over your home WiFi network. Doing that would allow you to take a laptop out to your shop, and connect wirelessly to your router. You'd be able to view/listen to any file, audio, video, pic.
I'm in the process of ripping my DVD collection on to an HDD and I hooked it up to the USB port on my wireless router. I'm much more inclined to watch the movies I own when all I have to do is click a file rather than go thumbing through my hundreds of DVD's. I can even access to them through my Playstation and watch them on my TV. I have a very cheap Sony Blu-Ray player that lets me access it too. This stuff is getting very inexpensive. Don't know how long it will last, but it's certainly cheap.
