I found the stealth BB battle charger at Target in Kent.

 

Cool pic on the front of his packaging.

Eh, but I unfortunately didn't provide a receipt or in-"box" images since I didn't know it was a new sighting at the time, so I could see how some people would be skeptical. This is super-duper proof, now.

I'm honestly surprised it took this long for a second sighting, though.
