I recently picked up this K&F Concept NP-FZ100 Battery and Charger Set for my Sony A6700, A7 III, and A7R III, and it’s been a game changer for my photoshoots. The set includes two 2600mAh batterie which are slightly higher capacity than the OEM Sony batteries and a compact dual lot charger with both USB-C and Micro-USB inputs. This versatility means I can charge via a wall adapter, laptop, or even a power bank when traveling.

The batteries fit perfectly in all three cameras, registering full compatibility with no warning messages, and they perform reliably, holding a full charge for extended shooting sessions. The charger is straightforward and displays each battery’s charge independently, which is reassuring when planning long photo or video shoots. The build quality feels solid, and the protective plastic covers for each battery are a thoughtful touch for safe transport.

On the downside, the charger isn’t fast. Charging two completely drained batteries takes several hours, so it’s best to charge overnight rather than expecting a quick top up.

Overall, this set delivers high-capacity, reliable batteries and a convenient charger at a fraction of the OEM cost. So it's an excellent value for any Sony photographer.
