Review on AODELAN External Battery Replace Batteries by Fred Whitehead

I recommend it to anyone who needs to shoot with full flash power. I have already used this at two weddings since receiving it, only two lines have been used. I use on Canon 600ex-ii rt. The refresh rate has greatly improved. I use it on a softbox stand most of the time, I've tried it on a camera and with a battery on my belt and it's heavy so I leave the battery on the stand and just take it. Flash if I should use the flash on the camera. I recommend this setup for traveling light and when working with a man and shooting without an assistant.
