K&F once again delivers a great product at a affordable price. Got these for a couple of photography lights I use, and wanted to use them wirelessly and these batteries makes it possible for me to do so. Battery life is great and within expected reasons. Charger does a good job of recharging quickly. Overall, I have no complaints for these...they work and do what I need.

I have a whole bunch of NP-F batteries (550's and 750's) and they take forever to charge on the regular USB chargers they came with.
This plugs into the wall (so it has higher power) and fast charges them.
Most importantly, it does 4 at a time AND has a charging indicator letting me know whether they're nearly empty or nearly full. I can look at the charger and know if a battery is good enough to use in a pinch.
The batteries lay flat in the charger (as opposed to standing), which makes the base a little longer than it needs to be, but I've seen other chargers that stand the batteries and are large enough to accommodate all sized batteries, which makes them much larger than necessary. This is small enough to fit with my gear and handy to have as I'm going through batteries on a shoot.

The batteries work great, I am using them in video lights. They power the lights great and for an adequate time. They are on the small side but it's giving an appropriate run time in a small and convenient package. My long runs stick out very far. The charger works great and charges quickly.

This charger and battery set works great. The batteries fit the NP-Fxxx accessories just fine. And the charger is compact and small for easy packing. The charger also has both USB micro and USB C ports for power in.

Standard NP-F series batteries. its on the lower end of mAh but they work great for monitors and other camera gear (in my case) that uses NP-F batteries. Come with a dual slot charger which works just fine plugged in through USB. I can never have too many of these and this is a great set for a good price for the batteries from a company that you can trust

I have a number of NP-F style batteries and it's always a pain to get them all charged up with the limited number of charges I have. This charger solves that problem and makes it much more convenient to get them charged up in bulk instead of one at a time. The charger interface itself is pretty basic, but it's not much different than the single battery chargers I have.
This does not appear to be a fast charger, as it takes a while to charge up even my smaller NP-F batteries. But being able to fill it up with four batteries at night and have them all charged up by morning works for my needs. The build quality is pretty good and is what I expect from the K&F Concept brand that I've grown to like. I'm pretty happy with this charger.

These F550s power my camera monitor just fine. For more power hungry items like high wattage lights, they only power to 60%, but again, work great for my 6 inch monitor.

the charger came with a cable to charge. what I like about this is that when you put the bigger batteries other types you would have to struggle to get them out. this one they thought about that and add a space to put you finger to disconnect the battery from the charger. the display shows them separately. it charges fast and portable. great deal to be able to charge 4 large Np batteries.

I use these batteries for monitors and lights when I'm filming. The 550's are good for about 3 hours on a monitor and are much lighter than the 750's I have (that are double the size/charge). Fortunately, this also means they charge faster.
I do wish the charger was a fast charger, but it's USB, not direct plug, so it can only supply so much power. The charging base is small enough to fit with my gear and has USB-C and micro (anyone use micro anymore?). The only downside to the charger is that it displaysonly charging and full, it doesn't let you know how far along they are (like 3-bars, for example). When I'm at a shoot, sometimes it's useful to know if the battery is almost full, and with this charger, I have to guess. I've also found that if I take a full battery off the charger for a minute, when I put it back on, it'll charge for another 5-10 minutes. I don't know what's happening, if it takes that long to tell it's full or what, but it makes me wonder if it's underfilling the batteries for some reason (poor design, safety, or some other reason).
So far the batteries charge quick and work well. They clip in easily.
