Dual-Slot EN-EL15c Charger

The Accessory Power 5491 is a dual-slot charger built for Nikon EN-EL15c batteries. It accepts power through a USB-C port and can charge two cells simultaneously in roughly two hours. The unit ships with a fast-charging cable and works with wall adapters, car chargers or power banks.

Power-source limitations

Photographers who can supply a 22.5W or higher USB-C adapter will see the full two-hour charge speed. Users limited to a 5V 1A adapter cannot operate the charger at all. Those with a 5V 2.4A source fall back to a slow sequential mode that fills the first slot before starting the second.

22.5W USB-C input requirement

The charger only reaches its rated speed when fed from a 22.5W USB-C power source. Lower-output adapters either disable the unit or force a slower sequential cycle. Check your adapter's rating before relying on the rapid dual-slot mode.

Questions about this item

How do I install the batteries and power the charger, and what step do people get wrong?

Insert up to two EN-EL15c batteries into the dual slots, then connect a USB-C cable to a 22.5W or higher power adapter; the common mistake is using a 5V/1A adapter, which will not power the unit at all.

What maintenance or replacement will this charger need later?

The charger itself has no user-serviceable parts; only the EN-EL15c batteries will eventually require replacement after their cycle life is exhausted.

What limit shows up first under sustained use?

With a 5V/2.4A adapter the charger enters slow-charge mode, filling Channel 1 first and then Channel 2 sequentially instead of simultaneously.
