Designed specifically for the AD600Pro Witstro outdoor flash, this AC Adapterfrom Godoxallows you to plug the light into a wall socket instead of powering it with its rechargeable battery. It gives you essentially unlimited runtime, making this an ideal accessory for long studio shoots. The product is composed of the adapter itself, which goes at the back of the AD600Pro into its battery slot, and a cable for connecting to a power outlet. The adapter unit accepts 100-240 VAC power at 50 or 60 Hz, and features an on/off switch for easy operation.
