The power cord on our EcoGlow chick brooder broke at the nub.
I’m pretty sure the reason it broke was the way we wedged the brooder power cord up against the wall of a plastic tub. I don’t think it was meant to bend at such an extreme angle with pressure.
I used a coping saw with a knife to free the nub from the plastic case. There’s not much wire to work with, so make sure when you cut it that it doesn’t fall back in the hole.
