This provides a 5.5x2.5 DC power jack from an ordinary 18 volt Ryobi tool battery. I use it with my TS100 soldering iron. Parts needed: - 1 x 5.5x2.5 barrel jack - https://www.mouser.com/ProductDetail/163-2325-E - 2 x AAA battery contacts: https://www.mouser.com/ProductDetail/534-204 - 4 x 16mm M3 screws: https://www.grainger.com/product/FABORY-M3-0-50mm-Machine-Screw-31JT09 - 1 x 2 meter 5.5x2.5 male to male power cable: https://www.ebay.com/itm/2-5mm-x-5-5mm-DC-Connector-Lead-Male-to-male-Power-Cable-50cm-1m-2m-3m-5m/382435803119 To assemble: 1. Solder wires to the power jack. 2. Insert the jack into a hole on the cover. 3. You can't turn the nut inside the cover, so you'll need to slide the nut and washer in place inside, then twist the jack to screw them together. I recommend using pliers to get a good grip on it. 4. Solder battery terminals to the wires from the power jack. 5. Slip the battery terminals onto a stem. 6. Slide the top of the stem into the cover. Depending on your printer, this may require some force after you line it up. It should end with screw tabs of the stem flush with the bottom of the cover. 7. Screw the base onto the stem and cover.
