Hi all. We recently bought our first tablet, an RCA Galileo Pro 11.4" 2-in-1, for a ridiculously low price ($87 US). It's principal use will be to run an application (OpenCPN) that allows us to plan trips for our sailing excursions. Secondary use will be as a backup navigation display. We do some web surfing, but not much. The tablet runs the app just fine, but the battery life is terrible (2 to 3 hours), so I would like to keep it plugged into a 12V DC socket on the boat while using it. However, the manual specifically says NOT TO USE THE DEVICE while charging on 12V DC. (It's apparently ok to use it while it charging from 120V AC). I really don't want to have to turn the thing off to charge it, then wait for it to reboot when I want to use it. I have unsuccessfully searched the web, and this website, for answers to the following questions, and the RCA site no longer lists this model. Here are my questions: 1) Why would this prohibition be in the manual? 2) Is this inability to charge on 12V DC (while actively using the tablet) common to ALL Android tablets? 3) IF I need to consider returning this to get a tablet I CAN use while charging on 12V DC, what inexpensive tablets (with internal GPS) are recommended? (We bought this primarily because the price point was so low, it was a relatively large screen size, and it was a 2-in-1). I would consider a dual core rather than quad core, to reduce power consumption. I will not be getting or needing cellular capability, as we have multiple phones.
