PHOLSY External Hot-Shoe Flash Battery Pack Speedlite Battery Box for Nikon SB900, SB910, SB5000. Replaces Nikon SD-9 (12 AA Batteries)

With not having a product reviews, I ordered this not knowing what to expect. I received it an hour before heading out the door for a 10 hour wedding. I was blown away that at the end of the night, I still had enough power to go a few more hours. I shot over 1000 images and never had one failed image due to the flash not re-powering fast enough. The only thing that I did not like was the case that it came in and trying to make it work attached my camera belt as it is bigger than the other battery packs that I had previously. I will have to get one made that will work, but I made it work for that day. It was nice to be able to look down and see how much power the unit had left as it has 4 lights that each will go out as the power drains. The power cord is heavy duty and the plug securesvery well into the flash . I am thinking of buying another one to hook up to my slaved speed-light that I use as my main light for my posed pictures. I recommend this to any one that needs to power their flashes for the long haul.

I have only used this product on one photoshoot so far. Battery loading and unloading is easy. Not sure how accurate the battery meter is since it seems like it would increase and decrease with the same batteries. The cord is a good length. I had trouble with the cord disconnecting from the flash during the photoshoot. I'm not sure if it's the fault of the flash or the battery pack. It definitely helps improve the cycle time of the flash. Overall I am satisfied with this product. I think I can find work arounds for the minor issues I experienced.

Exactly what I needed for my flash. The only suggestion I will make is be sure which pin connection you are needing. Even though I have a Canon EOS camera, I have Neewer after market flashes that actually use a Nikon connection. The original battery pack I purchased had Canon connection to I had to exchange for this one. Now that I have this one, it was exactly what I needed for longer, indoor photo events.

Used this with a K & F concept flash. I shot a five hour sweet 16. Approximately 500 flashes and could have easily kept going. Dramatically improved recycle time. I used this in conjunction with the green Duracell rechargeable batteries which are excellent. This pack is extremely light wight which is great given the weight of the batteries. Only issue is that the dot lights indicating full low power never reached the top “full” light despite fully charged batteries.

Works as described. Great backup when you don’t have time or a place to charge other external batteries. A bit on the heavy side with 12 AA batteries. Would of been nice to come with a neck strap. But for the price. You can’t beat it. Product looks similar to others just different branding. At this point just used it once. Not long enough to have a true review yet. But on the surface, so far so good.

never again !!!

Works great! Used it for a wedding, lasted me all day! I used the lithium batteries and had it on all day with no problems. Only thing I dislike is the weight which I didn't even notice throughout the day with being busy taking photos. It has a Velcro strap so I looped it through my belt and the cord was long enough to wrap around my body to my flash. Highly recommend!!!

+ It comes with a belt Pouch to carry the battery pack on you or on stand flash- Didn't notice any improvement on the recycling time. I still get many black pics because the flash doesn't fire constantly. I use Canon Speedlite 600EX II-RT
