SmallRig 5107 Portable Charger Case for EN-EL15c Camera Batteries With a dual-channel design, it allows for simultaneous charging of two batteries or single-battery charging. Equipped with an 18W USB-C fast charging port, it can fully charge two batteries in approximately 2.5 hours, significantly reducing charging time for boosted efficiency. The high-definition display clearly indicates the battery level for each channel, even when disconnected from power, ensuring 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. Intelligent circuitry offers multiple safety protections, including over-temperature and over-voltage safeguards. It monitors temperature and voltage, automatically slowing down charging during overheating, cutting off power in case of overvoltage, and employing trickle charging near full capacity to preserve battery health. Additionally, the charger comes with a fast-charging cable, making it compatible with wall adapters, car chargers, and power banks for versatile recharge options in any shooting scenario.
