Buy a decent deep cycle marine battery (about $100). If you have a power supply at home to run your charger off you may be able to charge the battery back up with your RC charger, as long as it has a mode for lead batteries. Charge at about 4amps is good. Otherwise get a decent jumper pack, I like the ones that have built in power inverters, also about $100 for one with an inverter but is very useful!
