Pearstone SB-4 AC Adapter for Vivitar 283 & 285HV Flashes

The Pearstone SB-4 is an AC adapter that allows the Vivitar 283 and 285HV flash units to be powered by 110V household current. This is especially useful for use in the studio. The adapter will also decrease the flash recycling time down from 10.4 seconds to 4.8 seconds, and it has a 6' (1.8 m) cord.

Note: The 283 and 285HV flashes require fresh AA batteries to be installed, even when using the AC adapter. With 285HV models manufactured after 2006, only alkaline batteries will allow the adapter to deliver proper voltage.

The SB-4 replaces the Vivitar SB-4 (239404) AC Adapter.
