[LCD Display] It charges two batteries in two hours. It has a screen to tell you the ststus of the batteries. Take up 1/3 the space of the Nikon Cgarger, And no cord

[11 lb] For times when doing field videography with my Nikon Z7 (meaning when I'm away from base camp and off grid for 3-4 days), I used to be battery-limited because for space and weight reasons I just could not bring as many Z7 batteries as I would need. But video work is battery intensive... the solution for me now is this charger and a hefty power pack along with only 3 Z7 batteries. Works great!

[9 x 4 x 4"] Got this so I could charge my D750 batteries in the field off a Power Stick if needed. Planning a trip where electricity may be at a premium and did not want to deal with a dead camera battery or two. I already had a short USB extension cable so the length of the dongle did not concern me. Made a test run with 2 batteries and no problems. One less thing to worry about.

[3.5 Hour] Bought this Nitecore UNK2 Dual Charger to use with my Nikon Z7 II. The camera came with the MH-25A Nikon charger but only does one battery at a time, I wanted to get another Nikon MH-25A but they are super scarce and have not been available for a long period of time. This Nitecore will do two batteries at a time, has a LCD screen that lets you know about the charging process and battery condition. So far this unit has performed perfectly for me charging the Nikon EN-EL15C batteries at least as quickly as the Nikon charger does or perhaps just a tad bit quicker. Works great, compact, solidly built and I have not found the short USB cord attached to it to be any problem whatsoever. I would recommend this little charger and would purchase again.

[4] A better charger than the factory one. It's super light (lighter than the battery) and smart. Being able to charge anywhere, even in a car is a great convenience.

[3.5 Hour] These are the best chargers around, period. Charges 2 batteries at a time fairly quickly, great display for information about the batteries AND you can use a USB power pack to charge in the field or in your car. I bought one for double Nikon en15's, one for Nikon en15 on one side and an an el14a on the other and one for double sided Fuji 126's. Small,lightweight great for travel and all around use. Priced right too!

[11 lb] I like this charger over others I have. For critical moment when needing charge, the via USB is absolutely great. Can charge while literally on the go when plugged into power bank, laptop or even solar with Goal Zero panels. Reasonably priced+holds battery secure enough while charging (use silicone hair tie or rubber band to ensure bind in case of hard jostling), plus LCD display has lots of info: indicates health + progress of battery charging. Only con is the cable is very short easy remedied with USB extension adapter. essential for on location shooting. No power=No shots

[11 lb] I love the Nitecore UNK2! I don’t have to worry about charging my batteries at the house if need be. I have recently been doing photos and video in nature where I am not near an electrical source. This solves my problem. I use the USB adapter for my car and my problem is solved! This product keeps you up to date on the charging process on its easy to read digital display. Thank you nitecore for such a fantastic product!

[3.5 Hour] What makes this charger so great is that it is smaller and lighter than the Nikon provided charger. Plus the LED screen shows you the status of the charging and not just a flashing light.

[11 lb] I purchased this charger specifically for some travel I had planned. It's smaller and lighter than the Nikon charger and charges two over the one of the Nikon. I was worried about the USB charging but it wasn't an issue at all. It is a bit slower than the Nikon charger but seems to do a better job of charging so I'm happy to wait.
