I gotta keep it real here. I know with the normal drama of handling power with typical CarPC's can vary quite a bit and makes for much chatter. I have had my Samsung tablet since the end of the summer and leave mine on all of the time. I don't have it connected to any power or ignition wiring. My battery charge lasts from 3 to even 5 days without needing to charge it. That's with internet music streaming and all the other data stuff like twitter, facebook, market updates, etc. All I do is have the brightness auto adjust plus I timeout the display and enable power saving mode. I turn off bluetooth, wifi, gps and only enable when needed. (Tasker app is your most bestest friend in the whole wide world :becky:

Ok, that's a good point. It does seem to go for days without needing a charge. I still need to power the converter though. So I guess I'll stick with the P O L i have and use it for that. Thanks man. I'm planning on getting that thing done and ready for install next week while I'm off. Maybe I can get it installed, even thought he rest of the system won't be anywhere near done. Lots to come that's for sure.
I was thinking about it last night and I have to have a power source to the tablet. I have to have it for the HDMI to work! So I need a charger up front. So I guess I'm back to my original question. Can I run them both off the same POL or do I need one for both, or should I go with a bigger device?
What type of adapters do these thing use? Can you simply use a USB car adapter? I have a Mi-Fi in the car with mini-usb connector. The Mi-Fi has its own battery, but i wanted to keep it on 24/7. It only lasts 4 hours on battery, So I bought a 5V 1amp USB car charger. So far the Mi-Fi has been on for almost 1 month.
The tablet has a usb to 30pin connector, and the converter has a barrel connector to it an goes to a wall plug. Both are 5v after testing, and I'm not sure of the watts on it.
I dont think its the watts you want to look for. Its the Amps. Say for example my Mi-Fi requires 500 mAmps at least to charge. So I paried it with a 1 amp charger. I took my numbers from the device of the wall plug itself, it should list it there.

If the voltage is a fixed number which in this case is 5v, and the current requirement is 500mA, then finding a supply that outputs 2.5w is the same thing as a device that is rated at 500mA. Just thought I would clarify this.
Dang it, I forgot to update this forum. I've been on my other forums updating and not doing all the audio over here, so I forget to post the tablet portion. I'll catch everyone up right now!
Ok another day in the books. Not nearly as much done as I thought I'd get, but I'm pretty pleased with the progress. I can see things coming together.
First up I started Version 2 of the tablet pan. The more and more I look at this and think about it, the more and more complex it seems. But I'm gonna keep working at it. Here we go.
If you will recall, I was going to use the docking station for this. After taping it up, and looking at it I decided not to do it that way. I decided I would just use the base part of it, and cut it in later. Thankfully I decided this after tape and not after glass or there'd be a version 3.
Time for glass! ALl my materials, including my coffee! Let's go for it.
Got some wax on it this time to help with the separation after drying.
Then I started the glassing process!
