The Cyclone PP-310 Compact Power Pack for Portable Flashes is an affordable, reliable and lightweight power source that works with most hot shoe and handle mount flash units that have a high voltage input, such as Canon 600EX-RT, Nikon SB-910, Sony HVL-F60M and select Metz units.
Building on the success of the PP-300, the PP-310 upgrades the original Ni-MH battery to Li-Ion and gives you 100 more full power flashes for a total of 500 on a 2-hour charge. Remaining power can be monitored via four LED indicators. Typical recycling time is approximately 1 second. The PP-310 is compatible with Quantum, Lumedyne, Dynalite and Impact battery pack systems and accessories. The package includes the PP-310 battery, a multi-voltage charger, car charger, removable belt clip, user manual and neoprene shoulder strap with quick release buckles.
With most compatible flash units, an additional flash cable is required to connect the battery pack to the flash.
