The Nikon MH-34 Charger is designed to charge the Nikon EN-EL15b and EN-EL15c batteries. If you need a spare charger, you’ve come to the right place!
To use this charger, you’ll need an AC adapter that supports USB power delivery, such as the Nikon EH-8P USB Charger, the ZILR 65W GaN 3-Port USB Type-C AC Wall Charger, the Anker PowerPort Atom PD 2 USB-C Wall Charger, or the Anker PowerCore+ 26800 PD Battery w/ 30W Charger.
Please note that the MH-34 won’t charge EN-EL15 or EN-EL15a batteries. If you’re looking to charge those batteries, check out the Nikon MH-25a Charger.
