Great batteries. Last just as long as the OEM Sony ones. Great charger too. Charges batteries to capacity in about an hour and even charges the OEM battery

Purchased this for my sony NEX . The original batteries were not holding charge well. These batteries brought my camera back to life.

The K&F Concept NP-FW50 Battery Charger Set is a lifesaver for my Sony ZV-E10 and other Alpha series cameras. The dual-slot charger ensures I always have a fully charged spare, ready for action. Its compact design and compatibility with various Sony models make it a must-have for hassle-free photography sessions. Highly recommend this reliable power solution!

The batteries fit and perform just like my original Sony battery. I don't see a noticeable difference in performance (either way, longer or shorter) which is fine. I like that the charger will accept power from Micro-USB like the camera or USB-C like almost everything else I own, so the chances that I have the correct cable are effectively doubled.

Later on down the road there may be some effects of different cells in the battery pack - and I'll try to remember to update this review if anything abnormal happens. But while they are fresh and don't have many cycles on them they are every bit as effective for me. Given the price difference and performance so far, I would buy the K&F Concept batteries 10 times out of 10 over another OEM battery the next time I need a replacement. The dual-power charger is a bonus.

I recently bought a used Nikon D3300 for use with some AF-P wide angle and telephoto zoom lenses as my older DSLR D7000 will not work with any of these lenses. The OEM battery that came with the D3300 is EN-EL14a and the battery is showing its age. So I ordered these extra batteries and charger set. I really don't need two batteries as I don't use this camera often as I use my other two mirrorless FF and APS-C cameras. But those extra batteries come in handy when I take the camera on vacation and don't have to worry about charging for days.

I have purchased a number of K&F Concept products over the years and they have all been of excellent quality. Those batteries and charger also look great. It came with a charger, two batteries and a generous 3ft charging cable with USB-A and USB-C end connectors. Note, however, that a wall charger is not included in the box. The charger has USB-C and Micro-USB input ports. The batteries were delivered fully charged. The charger works fine, but it has yet to be determined how long it takes to charge either or both dead batteries.

Just like the OEM battery, these batteries can be easily inserted and removed from the camera. Works as expected. These batteries should last a while. One day I'll update this review for the number of shots I get on each full charge. I am happy with this set and given the past history of the products I have owned from K&F Concept I would definitely recommend this set.

Great little budget battery and charger set. Charges batteries fast, works with both official and other branded batteries. Included batteries hold charge well and don't preform noticeably deferent from my official Sony batteries (although I haven't really pushed them super hard). The whole bit of kit is super easy to just throw in the pocket of my camera bag.

I bought the set for my Sony camera and I'm really happy with it. The batteries fit perfectly and last just as long as the originals—no difference in use. The charger with three slots is super practical, especially when traveling. The small display shows exactly how charged each battery is. I particularly like that the device can be powered via USB-C—ideal for use with a power bank when traveling. Solid quality at a fair price. In my opinion, this is an all-round successful set—a clear recommendation!

The set of a USB charger with 2 batteries

It has a large function, is also compatible and has an important function, with a camera connected to a battery with a low depressurise

I recently ordered this for my Sony ZV-E10 camera.

I just started using it and seems to work well so far. It’s better to be prepared and not need them, than need them and not prepared.

I haven’t used them for very long so I can’t speak to if or when they start to cycle or stop holding a full charge but, thus far these have been an excellent choice.
