Really pleased with this charger and batteries. Works very well, batteries sit tightly and quickly charge. Charger stays cool whilst charging. Nice and light for carrying round on holiday.I also appeciate the USB C and micro USB charging ports so it fits both my Anker power banks.I have the Fuji XT2 which eats batteries especially if using an auto tele zoom or burst shooting.Needed a new double charger as it ruined one of its supplied batteries causing it to swell so they were binned.Danger in unbranded products.I have acquired many K&F products and trust thier quality. It has now been used to cycle through my K&F and Fuji batteries many times.Always in use I will running them down to low battery warning level.So they get to fully cycle on charge. I number batteries and use them in rotation. After charging I always put meter on battery and check voltage before using battery, so far all within stated voltage parameters and they stay cool whilst charging.

Perfect and cheap spare batteries and charger. Works as intended.

Overall I am satisfied, they do not last as long as a genuine battery and in cold conditions drain very quickly (maybe 3X faster when I was at approximately 0 Degrees Celsius). If you can afford buy genuine, if not these are perfectly fine. The charger is handy though.

Firstly, the price is incredible. For two batteries and a USB-C charger, its so steal. Secondly, I'm blown away by the speed of delivery. I ordered this on Tuesday, delivery was meant to be Friday, I received the package on Wednesday (less than 24 hrs of ordering) without an Amazon Prime subscription. I wasn't going to order it at first because I felt it wouldn't receive it early enough to get the batteries charged for my shoot on Friday. Now I'm glad I ordered.Thirdly, the build quality looks premium, and looks sleeker than the battery that came with my Z5. Finally, both batteries work fine on my D750 and Z5, so no issues there.I'll post an update on the charge speed and battery life after a few weeks of use.

I seem to collect compatible Nikon batteries as I misplace them, replace them, and find them again. These are as good as any, and seem to last as long as the Nikon ones (although I've not done anything at all scientific to check that!). I've had these for a while with no complaints, and the charger works well for both the replacements and the originals. It's useful to be able to charge more than one at once.

I bought this item as I am a fan of K&F filters. The charger came with two batteries and was well packaged. Unfortunately one of the batteries did not work in my Z6III. I contacted K&F customer support via the Amazon returns process and was sent a complete replacement item - two more batteries and charger. Brilliant customer service and saved me having to go through the return process and shipping stuff back to Amazon. I will be buying more from them

These work and seem not to be obviously dangerous. Battery life seems broadly in line with the Fuji original. The batteries are slightly larger than the real ones, which ironically means that while they fit in the camera just fine, they're quite hard to get into the charger.The charger is a bit shonky. If you are charging two batteries and one finishes first, you can't just swap that one out with another that needs charging- the charger will often get confused and flash a red light, no longer charging. It requires unplugging from power and plugging back in to resume charging.So a little shoddy, but a lot cheap. Make of that what you will. As long as they're actually safe, it will probably be tolerable.

My husband uses these in his Nikon DSLR camera. Works well and holds good charge. The battery charger is easy to use and fits other nikon batteries in too.
