a power supply is the way to go. you can always use your battery when you go places that you can't use the power supply or you can put it back in your car, truck, or boat, lol.

car battery chargers won't work. i tried that before i had to go buy a power supply. they put out a little to much voltage. the chargers started beeping at me saying voltage input to high. i used to do the same thing with my old tekin peak chargers. hope that helps.
