Question about Sunpak 622 Super Pro TTL Flash
I own a Sunpak 622, and normally use rechargeable NiMH "C" batteries. I regularly have a recycle time of 5.5 sec. at full (1/1) power. Seeking faster recycle times, I purchased the Sunpak AD-26 AC Adapter. Using the adapter, I consistently have a recycle time of 18.4 sec. at full (1/1) power. I'm unable to understand why a constant power source, such as an ac adapter, seems to have less current/power/oomph/or whatever than a set of rechargeable "C" batteries.
That is my situation. I'd like to know if there is a way to "fix" this, and if this is common?
I have made Nimh pack which has 2900MAH cells and is very fast recycling.But beware that it will heat up Xenon(it needs cool down time before you fire full power repeatedly.Also its capacitor will be short life due to electrolytic(Same as fast battery chargers ruins the battery life).
And when its production is seized,I care it more.

I had the same problem - 10-11 secs on 240VAC. My solution was to get the Quantum Turbo SC for $450. It yields ~3sec recycle times. This pack for $150 should play nicely as well: http://www.adorama.com/JTMBPN.html?searchinfo=jtl+lancer+battery+pck It was out of stock at the time. The Sunpak TR2000 is $250, but it's Ni-Cd while the others are NiMH. There are other HV packs capable of powering the 622 w/ the fitting cable like Lumedyne IIRC. The AD-26 is still useful for non-action photography. The fastest time I saw posted is 1.5 secs, but it's a DIY job (search 'sunpak 622' on flickr). HTH,
