SmallRig Power Charger Case Kit for Sony NP-FZ100 Camera Batteries ensures full compatibility with Sony NP-FZ100. It holds two camera batteries and supports charging for both original and third-party batteries. Featuring an integrated 13,600mAh power battery, this charger case allows you to charge camera batteries without needing an external power source. It can also power other devices, such as smartphones, via its USB-C port or built-in cable, providing a comprehensive outdoor power solution. With a dual-channel design, this charger case enables simultaneous charging of two batteries or single-battery charging. It can fully charge two batteries in approximately 2.5 hours, significantly reducing charging time for enhanced efficiency. The high-definition display clearly indicates the battery level for both slots and the internal power battery even when disconnected from power. This ensures you're always aware of the remaining charge. If battery levels drop critically low, the battery icon will flash, alleviating low-battery anxiety during shoots. The fast-charging case includes a 36W USB-C port and a built-in cable, both supporting input and output. It takes about 3.5 hours to fully charge two camera batteries and the internal power bank. It can be recharged using a wall adapter, car charger, or external power battery, enabling convenient top-ups anywhere. The internal circuitry features over-temperature and over-voltage protection, monitoring temperature and voltage to automatically slow down charging during overheating and cut off power in case of overvoltage. It also employs trickle charging near full capacity to preserve battery health, ensuring safe shooting sessions.
