My storage garage has no power. I want to run a drill and a trouble light on occaision. O'reillys has some jap inverters,one plugs into cigar lighter & 2 hand held units that look like jump starters & I am told harbor freight has some(maybe that could be wired in the eng compartment. One guy talked about a deep cycle battery he uses in his storage shed w a harbor freight one & recharges it when it goes down. I am new on this, Do you guys have any suggestions on what would be the best way to go here? Thank you for your time.
