Universal Smart Charger

This charger can charge anywhere from 5-10 NiCad or NiMH battery packs (that's 6-12V, by the way). Use one of the many included connectors as shown in the image below, or just use the alligator clips.

Yes, that power cord is the same as the one that powers your PC, monitor, printer, etc.

I use this to charge the NiMH packs in my LarryK12.

For anyone who's interested, this is the label on the reverse side of the unit:

The little LED on the front is red during charging, and turns green when finished. It's a decent unit, and a darn sight cheaper (it costs about $30) than a full-featured universal charger like the Triton 2 ($120 plus a DC PS, which is about $60).
