Very happy with this battery pack. Having three batteries is super convenient, especially for long shooting sessions. They hold a good charge and perform just like the original ones. The charger is easy to use and charges all batteries efficiently. Great value for the price and perfect for photographers or content creators in 2026

Was discouraged to use non-Sony batteries on my new camera, but compared to paying 90 bucks for a single battery compared to a three pack plus a charger. Can’t complain I actually remind these since they lasted longer than my original battery

For the price of just one original battery, you get three (!) And a 3-way charger on top of that.
I use several A7IVs with 5 original Sony batteries, the new K&F replace my old RAVPower and Evatronic... all my batteries are around 3 years old. With the latest firmware 6.01, there is NO warning message when the battery is inserted (I have no idea whether they use the same chips for all batches), the percentages are displayed. Charging current per slot depending on occupancy: 1x 850 mA, 2x 550 mA, 3x 350 mA Tested
all my batteries, high energy consumption mode with Sony A7IV - 4k video at 25 fps 10bit with 8 series PP and 140 Mbit, MF.
Average values:
Sony 2h02min (5 pcs)
Ravpower 1h42min (2 pcs)
Evatronic 1h43min (1 pc) K&F *NEW* 2h03min (3 pcs) I guess (!)
that the K&F will have similar values as my old third-party batteries after the same period of use - so guess (!) I set the performance in relation to Sony at 80%. That means you get almost 2.5 times the power AND a charger for the price of an original battery. That is great. Long-term experience is yet to be seen, this is a snapshot of the new product - I'll update my review just in case.
Current: Buy recommendation 5/5

These work PERFECT with my sony zv-e1. My original sony battery that came with my camera actually gave out and is not working anymore but these have outlasted the OG battery which is crazy. Super easy to charge and worth every penny.

The K&F CONCEPT NP-FZ100 batteries are completely convincing. The battery performance is excellent — in everyday use, you hardly notice any difference to the original battery. The charger is very compact, very practical via USB-C and the display reliably shows when the batteries are fully charged. Absolute purchase recommendation for anyone looking for a reliable and handy alternative.
