AODELAN External Flash Battery Pack Battery Power Bank for Nikon SB5000, SB900, SB910 .Replace Nikon SD-9 (12 AA Batteries)

I use off-camera flash a lot but until now have only done relatively small projects. For those, one change of regular batteries was sufficient. However, I recently began a long-term project and I quickly found that I was getting through a dozen or more AA batteries each day or two. Not only was this not affordable, but it was also incredibly inconvenient and the recycling times were sometimes long enough for me to miss a second shot. I explained this on an online forum and quickly got the feedback that a battery pack based on NiMH cells would be the answer. Searching high and low I couldn't find one for my Nissin flashes and Fuji cameras. Then somebody pointed me to this pack with the Sony cord. I was still a bit unsure, but decided to buy it and try... Well, it has exceeded my expectations enormously. I have been running it on some regular AA cells, that had been indicated as insufficient when put into my flash directly, just to get the full value from them. I've been doing so intensively for two days, not only are these batteries powering the flash, but the recycle time is a fraction of a second. Once I've used up my stock of regular alkaline cells I shall move on to the NiMH cells. I was concerned that it would be too heavy for my belt, but it isn't - it sits comfortably at the waist all day. If I want to put my camera down, then it's easy to unplug the pack at the socket on flash.

I’ve tried it out - it works. So far so good. Only 4 stars because it is bulky, heavy, not a particularly ergonomic shape, the Velcro fasteners are a good idea but not really long enough to be truly functional. Probably too big and heavy because too many batteries that are essentially uneccessary.

Arrived faulty..battery terminals put in wrong...
