I am extremely pleased with the K&F Concept EN-EL25 Battery for my Nikon Zfc. This battery has proven to be a reliable backup for my camera, providing consistent power during long photo sessions. With a capacity of 1250mAh, I find that it lasts a good amount of time even when shooting in RAW and recording videos. It's on par with Nikon's original battery, which is impressive for a third-party option.

One of the best features is the USB-C fast charging capability. I love that I can charge the battery in about 2.5 hours, which is super convenient when I need a quick recharge between shoots. The USB-C port also means I can charge it directly with my phone charger or power bank, which has been a lifesaver when I’m out in the field without access to a regular outlet.

The battery fits perfectly in my Nikon Z50, and I haven’t experienced any compatibility issues or overheating. If you're looking for a high-quality, affordable battery for your Nikon Zfc, Z30, or Z50, the K&F Concept EN-EL25 is an excellent choice. It’s durable, fast-charging, and provides the power you need for extended shooting sessions.
