Great for traveling, the IM22 is lightweight and offers five adjustable steps with light indicators for greater lighting control and signals when the flash is ready to fire again. After a 70-minute charge with the flash's included USB-C cable, the IM22's built-in 3.8V lithium battery provides up to 440 full power flashes with a three-second recycling time. This flash works well for photographers creating close-up portraits or smaller product shots.
