I found out that when battery is in and then the adapter is plugged, the adapter shuts off (output voltage gradually drops to 0), and the only way to restart it is to unplug it from AC power and plug it in again. Personally I wouldn't risk it. If, as you say, the power cord is short there's a good chance it'll come out during the operation anyway.
If the device is running off battery, the output voltage of the battery will be increased by circuitry to run the device at the required level, however the voltage of the batteries themselves decreases as they loose power (and this is how the amount of charge left is calculated) When you have a power supply, it needs to provide the correct voltage.
When you have a power supply, it needs to provide the correct voltage. If there is enough current it will run the computer. If there is more current available then the computer requires to run it will charge the battery with the excess, and if it's not enough, the battery will provide power to top up the difference.
The main job of a power source is to supple electrical energy to a circuit. This is accomplished in different ways depending on the type of power source. Batteries provide a direct current (DC) and convert chemical energy into electrical energy. Electrons leave the negative terminal of the battery, which is called the anode.
It should work by taking the protection circuitry from an old battery and take a power bank that uses a lithium cell and connect the + & - of the power bank to the + & - of the battery circuitry. This way it should trick the phone into thinking it has a fully charged battery installed, plus giving the extra overcurrent protection from both boards.
The only time you're exclusively on battery power is when the engine is off (or, of course, if the alternator has failed). With the engine running the alternator supplies current that both recharges the battery- or, once it's recharged, maintains the charge - and runs the rest of the stuff on the car.

Electric Power Sources
Power sources supply electric power by pushing and pulling the electrons in a circuit. Without a power source, circuits quickly stop working due to energy losses. Think about the battery in your phone or tablet. When the battery runs out of charge, it stops functioning as a power source and your device quickly shuts down.
