Will update the other thread later but it looks like my charging issues are related to a wonky outlet. Lamp worked but the chargers didn’t. Now the chargers work on that outlet so it sounds like it wasn’t putting out enough current or voltage. Going to need to get it tested. Could do it myself but I don’t want to risk shocking myself on a live outlet. It’s fine when I’m working on smaller circuits but I’ll leave the big ones to the experts. 😛
