A crazy idea. Has anyone tried this.

Introduce the kids to something different ?
Give them a rotary phone and tell them to figure out what it is and how it works.

Gordon Three it is an Asus RTN56U Wireless.

ChooCHoo please I would be interested in seeing your set up. If you would rather email them my email is shuter1371@gmail.com

I could add 2 more 6 volts, but really I hate having the DVD's around the trailer and working if they are scratched ect.

I never thought about using my hot spot on my phone in place of the router.

how hard would it be to convert a router to a 12 volt DC then (sic) using an inverter for 120?

Perhaps you could consider increasing your battery capacity.

I do, but do it a bit differently. I use a pocket router as a DNLA server, and store Ripped movies on a USB thumb drive, and when watching on A TV instead of a tablet, I use a FireTV Stick, which is more powerful than a Chromecast. If you're interested in my setup, let me know, and I will go into details and pictures.

Both plans revolve around the TV, which is going to be your biggest drain, regardless of dvd player usage. The tv's backlight and audio amplifier will use more power than the built in dvd player. The chromecast is a piggy little device too, mine gets hot while operating, and I believe the power adapter that ships with it is rated for 5 watts (my 24in Vizio led tv only takes 9 watts)

What sort of router do you have that needs to be plugged in to power to operate? Either a portable hotspot or cell phone hotspot run off an internal battery and just recharge as needed. Some folks running full time might leave the hotspot plugged into the charger all the time, most likely an automotive type charger (12v in, 5v out.)

Since you haven't bought a Chromecast yet, don't. If you want a streaming stick, get a Roku. They are about the same price and the Roku works by itself. Rather than needing a phone/tablet to control it, it has a remote control. Plus it supports Amazon Video, a service Chromecast will never support (although there are workarounds.)
