Portable Non-Tablet screentime

Alright hold your judgements. I had my 2nd boy 6 weeks ago, super complicated pregnancy, 35 week induction, blahblah. My father passed away Friday morning. I have to travel out of state. My oldest boy is 2.

My son gets screentime, a little bit on iPad upstairs during the baby's first nursing session of the waking day, and then typically around dinner downstairs we use my CRT TV with a jailbroke wii with his shows on it.

I'm gonna need screentime in my home state- between baby, funeral planning, whatever else. I don't wanna just give him iPad. Is there a product for this? I have all his shows ripped off DVDs so he can watch them via usb.
