A device that wants to be supplied with 4v, will be destroyed if connected to 12v.
Do not confuse voltage with Amp/Hour capacity, which is what I think you are looking for.
Make sure the voltage matches the device. Then determine how much current the device draws. The power supply will be rated as to how much current it can deliver and for how long.
