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 recommend this for anyone who needs to shoot flash on full power. I used this on two wedding already since I got it, it has only used two of the lines. I use it on a canon 600ex-ii rt. The refresh rate has improved significantly. I use it most of the time in a stand with a soft box, I tried using it on camera and having the battery pack on my belt and it is heavy so for that reason I leave the battery pack attached to the light stand and just take the flash when I must use the flash on camera. I recommend this setup for light travel and if you are a one men show doing photos with no assistant.

works well and reduces recycle time down to <1 sec as advertised

I'm so excited about these! I bought 3 for each of my flashes. I was able to make it through a whole wedding without having to change my flash batteries. I used to have to change them at least 2 times during the night so it was so amazing to be able to set them up and not worry about them dying. They really made the recycle time better too. Myself and my second shooter were both set up to the off-camera flashes and sharing them the whole night and didn't have any issues with recycle time or delay. I'm so glad I bought these, it's stepped me up to the next level!

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.

I was a believer in this product but today was scary. I just put in 12 new batteries and tested it if the lights came on and it did. Went back to my camera case and my flash that was next to the battery pack was very hot and no batteries were inside the flash. I decided to check the battery pack and it was extremely hot and didn't want to open. I forced it open and all the batteries were leaking and swelling. No idea what happened but I would not be purchasing this one again.

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!

As a professional photographer, no need to worry about switching out batteries at events.Purchased 16 eneloop batteries. (4 for the flash) & was charged up all night for a 5 hour event. Only lost 1/4 of the power (indicator on the side) by the end of the night. recharged the batteries for next days event & level didn't even drop down. Took approximately 750 flash photos at each event with my 600EXII-RT flash & plenty of power left to take more.
