5 of 5 Pretty good battery charger. May 8, 2017
Reviewer: Donovan Lavinder  
This is a pretty good battery charger which I would keep in my Nikon DSLR camera bag because it's even more useful to have on hand whenever I am camping.

Well, it was awkward at first, until I realized it wasn't on this charger, the original wall charger has similar quirk too, it was the battery casing design to be blamed on.

Not to mention the usefulness have multiplied tenfold by the fact it has battery diagnosis, temperature and charge indicator - that way I will know if the battery is good, and able to judge if it's time for a new battery.

5 of 5 love this little charger! April 29, 2017
Reviewer: Brian B from Scottsdale, AZ United States  
I love this little charger!  It brought back 3 of 4 old generic Nikon batteries I had sitting on the shelf. One had been at .9 volts for at least 2 years!

The display is clean and bright. It's size is almost half that of the Nikon charger. Runs off 1a USB power so you can charge off a power bank while you are on the go.

Still not sure about the intrigrated USB plug. I'm sure it will be much more durable than the micro plug everyone uses. But, it's pretty short. No stars deducted, just a matter of taste.

Finally a high quality alternative to Nikon's 110v charger!!!
