Others will probably suggest all kinds of options, but I have been using my option for close to forty years without a hitch. I go to my local auto electrician's shop and get a car battery that is past it's best for around $10-15, which on average runs my mount and accessories for about 2 to 3 years, at which point I just repeat the process. Hard to get a cheaper power source than that.
A 4 amp charger can be used directly connected to the mount; I have done it myself once or twice, but make sure there is a fuse in the circuit.
