Thanks for the input and link.
One charger I just bought is there latest or last touch screen that is AC or DC powere.
Normally I just use DC power, but as there specs say 100-240V I wonder if it would blow up if I try it on 110v
The online specs say it's powered using 220v AC and It's only sold outside the states.
I bought the one that's coming from RCMart
