Hi. I have a couple of hand-me-down razor scooters. Kid size for little guys and gals. They don't have chargers. If you happen to have one sitting around and don't need it, I'd love to try to charge these to see if I can donate or gift the scooters. They would be the 3 prong female ones. I think it's the bigger one which is 12mm if I'm not mistaken.
If you happen to have batteries I might be able to use those too. Who knows if the existing ones are any good anymore.
