Thread Starter 
Would this setup work?
this monitor PYLE PLHR76. connected to this battery Anker® Astro Pro2 20000mAh via this adapter 2.1x5.5mm Male Jack DC Power Adapter.

also do i connect the 2 (+) wires (blue & red) together? btw this will also power my RPi + 2 usb dongles

ps. my bad if this is in the wrong area

I do not see the voltage/current requirements for that monitor anywhere. (Could you post some?) Assuming the monitor draws less than 2 amps (which should be a safe assumption) and the voltage of the external battery pack is set correctly, it should work.

Do you connect the two + wires together? Only if they are the same voltage. If they are a different voltage obviously you should not. Link to a datasheet please (or your source for this information)?

I just wanted to point out that LCDs gobble up a lot of power. If you went to a LED monitor you would greatly increase the battery life.

i.k. well so far i haven't found a LED monitor in the 3 - 5" range, so i settled on that one. have you seen any led ones? also i changed the model: i was going to use this one.
Car monitor temperature:
- Work: -10 to 50 degrees C.
- Storage: -30 to 70 degrees C.
Car monitor color: Black.
Power consumption: 3W.
Power supply: DC 12V.
Dimensions(L x W x D): 113mm x 70mm x 20 mm.

i'm going to keep looking for an led one. if i find one then i can lower the mAh of the battery
