ProMaster NPF770 Battery and Charger Kit

The dual charger is a lifesaver—fits perfectly in my bag and charges both batteries at once. I’ve been using these with my Sony gear for two weeks now, and they hold a charge just as long as the original.

I've been shooting all day with this kit and the charger topped up both batteries in about two hours flat. The included case keeps everything together in my bag, which is more than I expected for the price.

Bought this to have a backup battery for longer shoots, and the charger is surprisingly compact for a two-slot unit. The battery holds a charge really well, even after a few weeks of sitting idle.
