The Nikon MH-34 Battery Charger is a wall charger specifically designed for charging EN-EL15b and EN-EL15c lithium-ion batteries. The MH-34 needs to connect to an EH-8P AC adapter, EH‑7P charging AC adapter, or third-party AC adapter that supports USB power delivery. To use the MH-34 with an EH-8P AC adapter, you will need a separately purchased UC‑E25 USB cable.

The MH-34 battery charger cannot be used to charge EN-EL15a or EN-EL15 Lithium-ion batteries.
