Versatile & Easy To Use
By itself, on or off camera, it is powerful and easy to use to handle most situations with ease. The iTTl feature works well in quickly changing atmosphers/lighted subjects (Such as Wedding Reseptions and Events). Pair it with one or more 900's with the Remote or Master setting, and let the creativity begin. Would be 5 Stars, but the high temp shut down feature is a catch 22 (Can be avoided by use of the SD-9 Battery Pack).

Stopping in to order "another" SD-9 I'm what you may refer to as a Heavy User of the SD-9 units... I shoot an average of 32 weddings a year and also use them for beach shoots, portrait sessions and everything else in-between. This pack lasted three years and now I think something is simply wrong with the cord. Returned from a wedding and was unloading at the gear bench... I have a recent habit of putting batteries on testers to see what level they are on after a full day of shooting. The SD-9 batteries were still fully charged, so I knew I had a problem with it. I set up two SB-910 flashes up with fresh batteries.. added the SD-9 to one of them, then performed test flashes at 1/1 power... yep, they recycled at the same rate. Nothing being provided by the SD-9. So, I'm back to order another one to replace the non-functioning unit. Why five stars? Because I am happy with the years of abuse I've put it through, and the overall performance of the pack. I twist the cord, pull it too far, expose it to all manner of bad weather and cycle it fast, heating it up so much that is serves as a pocket warmer! If you're using the SB-900 or SB-910 units, this will give you a strong additional resource. The SB-900 over heats at the same rate with or without the pack. I like the pouch it comes with as I can just put that on my shoulder strap or belt... easy to load, convenient single plug and pretty decent construction overall. I definitely recommend it. Voting with my $$$.
I needed this! My SB900 flash & SD-9 battery pack work great together.Faster & greater power flash output,without heating up the unit. Speedy recycling & compact. Wished I had purchased it sooner!
Great addition to the SB-900 or SB-910. Instant recycling and I can go all day long. It comes with a holder that can be clipped to your belt. What I did is take advantage of the Kirk L Bracket on my camera, a Kirk plate, and the screw on part of this unit. I just screwed the entire pack onto the side of my camera. Makes a big camera bigger, but gives me freedom to move without getting the cord caught on things or wrapped around me. If you are going to take a lot of flash pics or need fast recycling, this is for you.
This has made speedlight use a breeze. Recycle times are incredible. Very consistent performance and power that lasts all day using my Nikon SB-910 speedlight. Can't believe I waited so long to make the purchase.
I bought two so I would have a backup or put one in my pocket for on-camera flash and one for the off-camera flash. A great product that does what it is supposed to do. Add batteries. Connect to flash. Fire away!!
I chose the SB-9 because all my other equipment is Nikon. The SB-9 is light and compact and slips onto my belt for convenient usage. It really does recycle my SB910 quickly for multiple, consistent flash bursts and I use it all the time. My only negative is the build quality of the internal battery holder. I've had to send mine back twice in three months for under guarantee repairs. The plastic battery holders inside my SB-9 shear off when inserting the batteries, meaning the AA size batteries are loose inside the holder. Maybe Nikon should use better quality plastic or use another material as the plastic is under stress every time the batteries are removed and replaced. Apart from this, I'm really pleased with the performance of the SB-9.
You will not be disappointed with this product.
When using bounce flash all day , and fill during a 90deg sunny wedding, I would not have got the 780 shots that I did if I was not using the power pack. Full power blast, Recycle, full power blast, recycle......
You cannot do without this flash accessory. The flash recycle time drops and the flash does not overheat. I bought one for each flash. I love them.
This power pack provides consistent output and excellent flashes. I have had three continuous 4 fps shots with flashes. Flashes came on each and every shot. However, this SD9 power pack is used only to shorten recycle time. That means your SB90/910 must have good batteries in it, as the battery pack cannot be used alone. Therefore, it should not be called an external power source, but as a supplementary power source to the main SB900/910. Nothing is mentioned in the manual about this requirement. As for the ready lights, none illuminates even with 8 fresh batteries. Called Nikon to ask about these questions, a rep had to put me on hold twice to consult with her manual or whomever before answering. Bottom line, the manual needs to be rewritten to avoid confusion.
