Reddit reviews Powerextra Multifunctional Battery Pack with USB Output for Sony NP-F970, NP-F975, NP-F960, NP-F950, NP-F930 Battery

I went this route originally, very cumbersome form factor. These are not really designed for cameras, although it will of course work. Instead, I replaced it with this solution:

Much more manageable and the bricks can power two more items plus the camera simultaneously. I've got 4 bricks and each will last between 1.5-2 hours on a charge.

Also, the brick you ordered takes FOREVER to charge up.

As some friendly advice, I'd cancel your order and instead go with the solution above. I'm confident you'll be more satisfied.

The items in this rig:

1. Small rig half cage 2254
   

• SmallRig Top Handle with Cold Shoe 1638

  Everything is powered off the Powerextra NP-F970 Battery.

I ended up going with this combo.

You can charge your camera from any monitor that takes a Sony NP-F battery, using this battery. It has a DC output and a USB output. From what I understand, you can power the a6500 either through the USB or with a dummy battery.

Dummy battery is more efficient as you get direct power, where USB merely charges your battery as you're using the camera - so all you're doing is basically slowing the drain of your battery, though it's a little 'cleaner' of a solution, and you don't run the risk of a bad dummy battery that misregulates the power input and fries your camera.

Aside from the Shinobi, check out the Portkeys, there's a 5" 1500nit or 7" 1200nit option for $289 and one cool thing about it is it actually has a DC output built in so you can use any Sony NP-F battery.

Did some research on the NP-F batteries, looks like they last about 2.5-3 hours EACH camera only, so both can run the camera only for 5-6 hours.

I also got 2 of these NP-F Powerextra batteries. They are a little more expensive at $22 each but they have a built in meter, 1 USB and 1 DC port that's great for powering a monitor if you don't have a D-Tap to DC cable..
