Will a Siemens e charger work for Rexton

Does anyone know if a Siemens e charger that is set for Pure RICs will work for Rexton Cobalts? I know they are very similar, but will Cobalts fit and charge in the Pure charger inlay. E chargers set for the Siemens Pure are pretty easy to come by at a discount, but the same isn’t true for ones that say they are for Rextons.
