Dynacore DV-2S 雙 NP 電池充電器

The parallel circuits are exactly what I needed since I shoot with two different NP batteries and always forget which is drained. Both slots topped off my 7.4V packs simultaneously with no hiccups, and the status lights make it easy to see when it's done.

Finally a charger that handles my mismatched NP batteries without complaining—the two parallel circuits let me top off a 7.2V and a 7.4V at the same time.

The dual slots are handy when I've got a 7.2V pack and a 7.4V pack that need topping off at the same time, and it's nice that each circuit runs independently. It's not the fastest charger I own, but it gets the job done without fuss.
