Hopefully someone has done this with something at a reasonable cost.
Depends on how many watts they will be operating at and your defination of reasonable. An astro Flight switching power supply will provide 13.5 volts at 12.5 amps.which is approximately 168 watts available here for $70
. A 12 volt battery being charged(maintained) with a charger will power a bunch of chargers depending on the size of the battery and the charger output. I use a 80 Ah deep cycle gell cell with a 45 amp. 13.8 volt power supply maintaing the battery. Six chargers,two Ham Radios all running at once and never a problem.
