This two-pack of batteries from K&F Concept is an absolutely essential accessory for any Lumix owner using the DMW-BLK22 batteries (S5, GH6, S5IIX, etc.). Theses are way better than any other option I've used.

The standout feature is the built-in USB-C charging port and fast charging capability. This makes then super convenient as you can charge them with any USB-c power source. I can charge multiple batteries at once even if I forget my charger. It is nice that they include the USB-C cables, so you have everything needed right out of the box.

Not only is the charging better, but the performance is superior. These batteries claim 2520mAh and 18.5Wh capacity, which is better than the Panasonic OEM specs (around 2200mAh & 16Wh. In real-world use, they provide excellent, extended power. They also slide into the battery compartment flawlessly, just like the OEM batteries.

Lastly, a small but awesome detail: the white casing makes them easy to spot in my various camera bags, whether the pockets are dark or brightly lined.

For a fraction of the price of one OEM battery, you get two higher-capacity batteries with vastly more flexible charging. This is an easy 5-star recommendation!
