I used to have a charger, but I can't find it anywhere in the house. I think it may have been tossed out in a bit of "spring cleaning"

.
Though I got the last one from shiningbeam, I am anticipating some Amazon credit and would like to use that. Thing is, I'm not sure what is total junk and what is worth a gamble. Needs to be able to handle at least 2 cells.
TIA
