@helpabrothaout the original wall charger from Schumacher Electric for your SL-1 is part number 93026927 You can contact them on here SCHUMACHER ELECTRIC CORPORATION, 801 BUSINESS CENTER DRIVE, MOUNT PROSPECT, IL 60056-2179 or get an aftermarket replacement from places like this or even at common places like this.
Try getting a universal laptop power pack. This normally can adjust to the right voltage and has the right tip.
