Category: 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.

Michael D. ★★★★★ Oct 22, 2026

Charging both EN-EL15 batteries at the same time has cut my prep time in half before shoots, and the compact footprint means it tucks right into my camera bag without adding bulk. The single-bay option is handy when I only need a quick top-off, too.

Steven U. ★★★★★ Oct 21, 2026

Having two batteries topped up at once without needing a wall outlet is a huge timesaver. The compact size fits easily in my camera bag. I’ve already used it on a weekend shoot and both batteries were ready well before I needed them.

Charging two EN-EL15s at once without a wall wart is clutch for my weekend shoots, and the compact body slips right into my bag. The simultaneous slots cut my turnaround time in half, which alone saves me from travel anxiety.
