AODELAN External Flash Battery Pack Battery Power Bank for Canon 600EX II-RT, 600EX-RT, 580EX 580EX II, 550EX,MR-14EX，MR -24EX .Yongnuo & Godox Speedlite Replace CP-E4N & CP-E4 (12 AA Batteries)

The battery pack is sturdy and has an on/off switch. Very easy to carry on your belt during long photo shoots. The battery pack still had a strong charge after 6 hours of use during a wedding!(I replaced a Nikon S9 which does not have an on/off switch.)Note: it requires 12 batteries - a bit of overkill, but works well! (other pack only used 8). Also weighs a bit more. Overall, it's a great product and the cost is very reasonable. I highly recommend it!

I shoot a lot of boudoir, glamour, and portraits in Las Vegas. I often shoot in client's hotel rooms and got tired of the time and effort required bringing in studio strobes with all the cables and power cords. I used to work with an assistant to help with all the equipment and it was not efficient. I put together a total location lighting kit with Canon 600 series wireless battery operated strobes, lightweight stands, collapsible softboxes, and the AODELAN battery packs. I like to shoot fast and these battery packs never let me down. I keep my flashes at 1/2 power or less for most setups and I can shoot as fast as I want with every unit firing without fail.The battery packs are well made and nice to look at and the having 12 batteries is great. They have just enough weight and the power cord is long enough to usually be able to strap them to the base of the stands so they double-down and help stabilize my lightweight lightstands as well.I am very pleased that I purchased these packs.

I am a professional photographer and I couldn't have been more thrilled when Nikon released it's newest speedlight--the SB-5000. This new generation of speedlights used radio control instead of optical control and that flexibility is HUGE for professionals. After looking at all the options for battery packs, I chose this one because of the mix of small size, ease of use and price. IT was a great call on all counts!It uses 12 AA batteries and powers the speed light for over 1000 shots. In fact, I haven't bothered to count. Before the COVID crisis, I was shooting 4-5 restaurants a week and the batteries lasted me over a month. And while I didn't know it at the time, the power-pack greatly reduces the recycle time for the lights. The SB-5000 is already a superior speed light with lots of power and faster recycle times than the other Nikon speed lights, but you'll notice a big improvement with these power packs. At lower power settings, the speed lights will allow you to shoot almost continuously and at higher power settings, your speed lights will recycle in about 1 second.In my kit bag, I now carry three SB-5000s and three of these power packs and I can shoot all day and all night without worrying about needed to replace batteries. And all that for a fraction of the cost of other solutions. Highly recommended for anyone doing serious flash photography.

The unit worked as advertised. I needed to extend my flash for a up coming photo shoot, and this unit was great. You do have to have batteries in your flash for this unit to work. It allowed me fast recovery time for shot to shot. A little heavy, but what do you expect with 12 AA batteries in it. Shot over 1300 shots and still had 1 LED lit.

I used this for my SB910 speedlight for a full night of shooting and it was great. Didn't have to waste time switching out batteries. I attached this to a stand with the speedlight and extra weight was not an issue.

Bought this for a small indoor shoot-low light that needs the support of my speed light. This product absolutely did what it's made for and definitely made the recycle time of my Canon Speedlite much faster (3-4 seconds delay and it's ready to go again) The case it came with makes it super handy to strap on my tripod, It seems you can strap it in your belt too! Overall, I am pleased, not sure yet for longer use, it uses a lot of batteries so I suggest buy rechargeable to make it worthwhile.

This unit not only helps with recycle time of my Nikon SB910 it is a lifesaver for batteries. SB910 and drain a set of batteries real quick even when shooting at 1/4 power. When I first got the SB910 I would have to change batteries 2 or more times a night to keep up with my shooting. When I plug this unit in, the SB910 can make it through 2 or 3 nights of my typical outdoor shoots before needing batteries. The strobe itself must have some battery life in it for the 2 to operate as a unit but this external battery pack provides the power for the actual flash. Love the fact that this battery pack has LED lights to indicate the amount of battery life left in the unit. It holds 12 AA batteries but it performs well and provides long battery life. Carry case is not easy to attach to my person or belt but w a little creativity one can manage to keep this unit close at hand.

I meant to return it and unfortunately forgot to within the timeframe. It's heavy, bulky and would never work well for weddings with all of the other heavy items (that are needed) that I'm toting those long days. Bummer!
