【Voltage Compatibility】
When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.
【Plug Type】
Our products use Japanese plug types (A or B type).
Please use a conversion adapter if necessary.
【Important Note on Transformers and Adapters】
A transformer adjusts voltage to match your device’s requirements.
A conversion adapter only changes the plug shape and does not adjust voltage.
Using only a conversion adapter without a transformer may result in damage to the product.
【Liability】
We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer.
[Upgraded Multi-Strobe] NW645II-N speedlight supports functions such as TTL, HSS (high speed sync) up to 1/8000s, optical slave mode, strobe flash, and rear curtain sync, enabling lighting with a high guide number (GN58, ISO100m). A clear LCD screen displays all the information you need for accurate configuration.
【Premium Flash Output】Flash output is adjustable from 1 to 1/128 in 1/3 steps according to the actual ambient light. Short recycle time of 0.1~3.5s and flash duration of 1/300~1/20000s allows you to capture every moment. To speed up recycling, you can use the SD-9 external charging port. Stable 5600K daylight provides consistent color temperature for every shot.
[Second-curtain sync] NW645II-N supports second-curtain sync, where the flash bursts at the end of the exposure and the movement stops during that time. This handy feature makes it easy to achieve bright photography with smooth and expressive motion trails.
【Optical Slave Control】NW645II-N is compatible with original master flash units and can be activated by them when set to the same channel. It also supports S1&S2 mode, which can be triggered when the master unit is in manual mode and TTL mode respectively.
[Flexible Bounce Angle] The flash head can rotate up and down between -7° and 90°, and can rotate 270° to reflect the light onto the wall, allowing you to take natural photos with less shadows. Diffusers and reflectors create a wide, diffused output with fewer harsh shadows.

Product description
Supports TTL, 1/8000s HSS, manual, optical slave, S1/S2 optical control, strobe flash, flash exposure compensation. High GN58 guide number allows for long range flash.
Rear-curtain sync allows the flash to fire before the shutter closes, giving you ample exposure and a smooth light trajectory.
With optical transmission function, NW645II-C can act as a slave unit when it is in the same channel and group as the original master speedlight.
1/128–1 dimmable to accommodate various light conditions, and a color temperature of 5600K±200K for natural colors.
The flash head can tilt -7°/90° and rotate 270°, and the diffuser widens flash output and reduces shadows.
