Trying to figure out what this is lol. Been out of the hobby for a while and I'm assuming it is a timer for the lights, but it does not have the adapter. So trying to figure out if it would be worth it to buy a new adapter or not. Also, disregard the circled part, that was just me asking the seller if they happened to have the power adapter.
Any JBJ nano cube DX people have this attached to their tank?
