Works Perfectly in the Lumix S5 — Charges Just Like OEM, plus directly
The K&F CONCEPT 2520mAh DMW BLK22 battery fits my Panasonic Lumix S5 perfectly and performs exactly as expected. It comes with a USB-to-USB C charging cable and clear documentation.
Charging performance:
• The instructions recommend using either the original Panasonic charger or a K&F Concept charger.
• I also tested charging the battery inside the S5 using the camera’s USB C port, and the camera’s charging lamp stays solid — confirming it charges normally with no errors.
• You can charge it the same ways you would the OEM battery, plus you get the option to charge the battery directly via the included USB C cable.
Power details worth noting:
• The printed instructions that come with the battery list the input as 5V/1–1.5A.
• K&F’s website states USB C charging supports up to 5V/2A (Max).
• For reference, the Lumix S5 uses a 5V/3A charger for continuous power or charging while shooting, so it’s helpful to know the battery’s limits.
Overall, it’s a reliable, well-designed alternative to the OEM BLK22 with flexible charging options and no compatibility issues in the S5.
