Here's a Collins dynamics handheld spotlight.
We hooked it up to 12VDC - it turns on and the battery charging light comes on.
We didn't leave it plugged in long enough to see if the battery charges or not, sorry.

We're a surplus store, and we aren't experts with most of this stuff;  we don't make any guarantees beyond what's stated in the listing & pictures.
