Yes it does. It works along the lines of a battery charger, You plug into a 110 power source and it will charge and run your 12 volt battery and 12 volt devices.you will also have to get your own 12 volt fuses and 110 breakers as they do not come with them.

No, it supports 12V-24V DC only. Also, this item is not self-powered (power needs to come from another DC power source).

The input current is 12volts 1000mA used with an external adapter. Does that work for you?

No, there is not an external power source included, it only comes with a USB cable. However, you can connect this USB cable to one USB power supply that can be connected to your +12VDC car adapter, they are very popular now.

It does not come with it's own power supply or connector. All it has are leads to attach the power supply. So yes, it can easily be hooked up to a 12v battery cage or power supply.
