Promaster 3757 Universal+ Battery Charger

I was surprised how quick this charger works — my old lithium ion pack was fully charged in under two hours. The LCD screen is a nice touch, makes it easy to see the charging status at a glance.

I was a bit skeptical it would handle all my old camcorder batteries, but the LCD screen makes it easy to track charging progress. It got a stubborn 7.4v lithium ion back to full in under two hours, which is faster than my old charger ever managed.

Got this to replace the charger I lost on a trip, and the AC/battery pack option is handy for charging in the car. It handled a mix of AAAs and a 7.4v camcorder battery without fuss, though the two-hour claim feels a bit optimistic for the larger ones.
