【45W PD 4 Channel Fast Charging】 The NW-Z4 efficiently charges up to 4 NP-FZ100 batteries simultaneously. The Type C input port supports 45W PD fast charging protocol. To achieve full power output, use it with a 45W or higher PD charger (sold separately), and it can have four 2280mAh NP-FZ100 batteries fully charged in 2.5H. Note: When using a USB A adapter, make sure it supports the QC 12V protocol; otherwise, this charger will not work. The NEEWER PD 100W USB C GaN Charger is recommended 【Portable NP-FZ100 Charger with Battery Display】 The NW-Z4 charger is favored for its compact and lightweight design, weighing only 4.2oz/120g, easily slipping into your backpack or gear bag, providing a streamlined charging solution for outdoor shooting. Integrated with a battery display to show the real time charging status of each battery once plugged in 【Full Circuit Protection & Undervoltage Activation】 All the 4 slots of the NP-FZ100 charging dock provides a rated output of 8.4V/1A. They use an advanced circuit to prevent short circuits and overcurrent and ensure safe charging. Additionally, the charger features an undervoltage activation function, which will lift the undervoltage protection on batteries that have entered sleep mode due to low voltage, so as to restore their full performance 【Efficient Heat Dissipation】 At the bottom of the NP-FZ100 battery charger are densely arranged ventilation holes, which effectively expel heat generated during extended charging. This design not only prolongs the charger's lifespan but also enhances safety during use 【CNC Precision Machined】 Each slot of the NPF battery charger is engineered with precision to ensure a tight fit with the charged battery, making sure the charging is stable and effective. A 45W PD type C to type C fast charging cable is included
