The plugs come in many different sizes so I would take the SAT into the store and correctly fit the plug. There usually is a octopus of plugs hanging near the display to fit the correct one. <o:p></o:p> But first……….<o:p></o:p> <o:p> </o:p> A DISCLAIMER:  Before I would go through the trouble of outsourcing from RS I would try to get the correct recharger from Sanderson. I wouldn’t want to void a warranty or toast my expensive SAT and besides we can keep the monies circulating in the brotherhood.
