2-Pack of EN-EL14, EN-EL14A Batteries and Battery Charger for Nikon D3500, D3100, D3200, D3300, D3400, D5100, D5200, D5300, D5500, D5600, DF, Coolpix P7000, P7100, P7700, P7800 Cameras

I bought these to use with my Nikon D3100 and they work perfectly! I didn't really need the extra wall plug, but for $4 more than the cost of just the 2 batteries I figured it was a good deal. I have yet to try the car charger, but both batteries charged perfectly and work with my camera, and the wall charger works with my original factory battery as well :)

On receiving the batteries I immediately plugged them into the charger to make sure they would work in my Nikon D3200. After a couple hours the first battery was charged and voila it worked great in the camera. Just as advertised. I haven't counted the amount of photos I get with one of these batteries compared with the brand name but they both feel as if they're lasting the same amount of time for brand/off-market battery. The plug in car charger is a plus. I do a lot of shooting at the beach or bay. Having a car charger to charge your battery is a bonus when driving home and something catches your interest. No need to worry if the battery is charged.

The batteries work great but do not have as much capacity as a oem battery. Not a big deal as this whole package is cheaper than one oem battery. I haven't tried the car charger but the wall plug in portion of the charger works fine. Great value!

I purchased the ecoEfficiency 2-Pack of batteries for my Nikon D3400 in July of 2017. I had just purchased my first DSLR camera and needed some extra batteries, so I decided to give these a try because this set came with another charger, a car adapter, and two batteries. I haven’t left the United States, so I haven’t needed the European adapter.The batteries charge quickly. I haven’t timed the use of the batteries, but I have noticed they don’t quite work as long as my OEM batteries. I did expect this because of the price. I have used them in rotation with the battery that came with the camera over the year and a half I have had them and they still work just as good.The charger that came with the pack has folding prongs on the back making it easy to plug in or take with you on the go. It has an adapter for your car, which is super convenient. I have used it many times in the car as well as at home and the charger works perfectly both ways.Overall, I am very happy with this pack. I only took off the one star because they don't last as long as an OEM battery. If you have issues with your camera not accepting the batteries, I would recommend contacting the seller before giving up on them.

Purchased the ecoEfficiency battery batteries and charging system from Amazon Prime, Big Mike’s Electronics was the supplier. The package came as promised. I’ve had a chance to use both batteries, I’ve charged my existing battery and both charger and batteries are working fine. Mikes did an outstanding job with product and service.Thank youThomas

I'm very satisfied with this charger. I like it better than the one that came with the Nikon camera bundle. That charger was just fine, but this charger was smaller, and more portable. Not that the one coming with the camera bundle was so massive, but this one can also be used in a car cigarette lighter. The Nikon couldn't.It also has a different, clearer way of letting you know that the battery is charged, The Nikon charger didn't have a particularly clear way of indicating a full charge. This chargers indicator light changes color. The Nikon charger just glowed different and I was never sure if I had a full charge.The price is also a plus. It's less costly then others available.

These all work, the car charger is nice to have. One issue with the batteries is that they don't seem to last as long as the original that came with it. They're also visibly different then original which is nice to keep track of which are charged and not. I didn't need extra batteries I was just looking for a car charger but with this price you can't beat it.Update: I’m a bit late on the update but these batteries no longer work, they lasted about a year to 1 1/2 years, the chargers still work great though so it might still be worth it to you.

More than satisfied with these batteries. They hold about the same charge as my OEM Nikon batteries. I have not had the chance to use the car charger, but I did use the adapter when I went to Germany. It turns out the adapter also worked with other electronics that I took (like phone chargers and other small electronics). Cannot beat this price! You will not be disappointed in these batteries if you need extra. Perfect for video shoots! Also, I noticed some people were asking if the charger works with the OEM battery. I guess it just depends but for me the OEM battery charges on this charging port and vice versa (the replacements charge on the OEM charger).
