Category: Batteries & Power Battery Chargers

Two batteries are better than one, but only if they are charged and ready for action. The ProMaster Dually Charger can charge two batteries simultaneously, or just 1 if required. It is compact and convenient with a USB-A input cable that neatly stores itself in the bottom of the charger. 

Since it draws power from USB sources, you can use the Dually Charger with a USB AC Adapter (not included), laptop, power bank, car charger, and more.

Amelia O. ★★★★★

Finally a charger that actually keeps up with my shooting schedule – both slots charge at the same speed whether I plug in one battery or two. The compact design means it doesn't take over my whole bag, which is a nice bonus.

Matthew N. ★★★★★

Charging two batteries at once has been a game changer on shoot days, and the compact size means it slides into my bag without eating up space. Even when I only need one topped up, it handles that fine.

Amelia Q. ★★★★★

Charging both camera batteries at once before a weekend shoot saved me from the usual scramble. It's small enough to toss in my bag, and I like that I can still run it with just one battery when I'm in a hurry.
