The charger works very well, not fast but solid, it has both a USB C port and a Mini USB. The C port is a real plus. The batteries have held up to all day several hundred photo shoots so far so good.

The is a great value for the money if you own a Nikon Camera: I have owned several Nikon Cameras and one of the biggest issues I have always had is the charger going bad! This charger was one of the best replacements I have every purchased!

Quality: The build quality is pretty good: The plastic feel is somewhat on the light weight side, but it feels sturdy enough to endure constant transport and on the go use!

Performance: The charging performance is okay compared to the original Nikon Charger. This charger takes about 90 minutes to 2 hours to fully charge both batteries! The Original Nikon Charger took about an hour to fully charge. Not a deal breaker for me.

Battery Life: The battery life is really good for these to be after market batteries! I was able to get through two separate photo shoots without having to recharge either battery. That is pretty impressive during a 4 hour shoot!

Great option for aftermarket Nikon Charger.

These normally are expensive but this charger set pairs great with our nice camera. I like having extra chargers so we are never out of battery when it really counts.

Any photographer knows the first rule of cameras: the battery will run down just when you need it most. So extra batteries are a must, especially when using DSLRs to capture video. I get about 30 minutes of reliable recording time from each battery, so I keep half a dozen charged for any given event.

This collection of two batteries comes with a charger where the two included batteries can be charged simultaneously. That is important. It powers from a USB connection - super convenient for almost any venue and cars where you already have your USB adaptor in place.

The charger has red and green LEDs for each battery to indicate when a battery is fully charged. Super reasonably priced for getting both the batteries and the charger!

These gave about the performance I expected. So a good choice!

I am always looking for extra batteries for my camera. I saw these on vine and had to order them. The batteries work great in my camera but the real star of the show is the charger. It seems to charge 2 batteries faster them my previous charger so that is a bonus. It also gives me an extra charger so I can charge 4 batteries at once. I am very happy with this order so I give it 5 Stars.

So far the charging and the battery life both are well. The future will tell if that stays true. I like that I can now charge two batteries instead of one and always have my camera ready to go for awesome shots.

I'm really happy with this battery set. Having spare batteries on hand is great, especially when I'm traveling and I don't know if I'll be recharging anytime soon. I love that these charge through USB, which makes it easier on the road if I do need to charge them.
So far they work just as well as my Nikon battery. I haven't done a shot count on them, but I'm sure they're fine. These batteries work in my Nikon charger, and vice versa for the Nikon batteries in this charger. You can tell they are well made and I've used other K&F Concept products before and have always liked the quality. Totally worth it!

Fast charger and good batteries. I go through a lot of batteries when taking product photos because the video output is usually on so I can see lighting changes through the lens. Having a fast charger and two extra spare batteries handy makes a big difference. The battery life seems as good as anything else I have, and so far they are working well. The charger is compact, too. Being able to charge two batteries at a time instead of one as in the Nikon charger is a major plus. Altogether, a great setup and a worthwhile addition to your gear.

I like that they came with a charger, and a charger that will charge 2 batteries at the same time, with a separate indicator for both batteries! The charger is flexible, it comes ready to use USBC, or Micro USB The batteries fit perfectly in the camera, are the same rated power as my original battery, 1050 MAH. Now with two spares, there should be no worries about running out of power! The D5100 is pretty good about not eating batteries, so this should easily handle a heavy shooting day! They certainly seem like a good quality product.
