I really like the last one the best but im not sure if it will work for what i need it for. I need to be able to power them by a 12v rechargeable battery and I know the first three can be powered by that, but idk about the last one cuz it says that it comes with “1 x 100-240V Power Supply.” Does that mean that my 12v wont be able to power it? PLEASE HELP!

For the last one you need a 12V DC 2amp power supply. So be sure your 12v battery can provide 2amp, which for most of the batteries it will.
