The PP-600 will give you approximately 900 full power flashes with speedlights and 400 flashes with monolights on a 4-hour charge with a typical recycle time of 1 second for speedlights. Remaining power can be monitored via 3 LED indicators. The package includes the PP-600 battery, a multi-voltage charger, removable belt clip, US, UK and European plug adapters, quick release shoulder strap and a user manual.
With most compatible flash units, an additional flash cable is required to connect the battery pack to the flash.
