Ac or Dc don't matter for me I bought a good beefy deep cycle marine battery and I wanna say like a 1000 watt inverter from pep boys for $200 for the pair you can charge and fly anything all weekend on a single charge of the marine battery and power 12 volt LED lighting in ur trailer, Husky also makes a 1000 watt 2 stroke generator with 1500 watt surge with breakers for like $249 which has both 12 volt and 120 volt plug ins with leads maybe a bit more expensive and less creative than a pc power supply but non the less a bullet proof solution that won't leave you stranded add a $69 ship n shore charger and you are 100% prepared to charge anything anywhere anytime
