Listen up, Sony FX9 users...This thing is such a huge help on set. Now you don't have to fool with having tons of BP-U batteries with you. Simply connect this to your BP-U battery slot and plug in the other end to a p-tap port on a V-mount or Gold mount battery. No more switching batteries mid shoot!

And don't worry if you're not using an FX9. It works great for any camera that uses the BP-U system (like the FX6, FS7, and FS5).

Simple and effective. We love that, and are confident you will too.
