Q: 1. When camera/coupler/Tether Tool is operating, suggestions of how to keep battery drain from exceeding the simultaneous charging? I have found it will not do both at the same time. Thanks.

A: It works for me. Keep in mind you have to use a power bank or charger that outputs at least 2 amps (the one i use is 2.1 amps). I tried with a power bank that only outputs 1 amp initially and that gave me the same problem as you have.

Q: 2. Do I need to buy a Coupler to connect my EOS R5 to the AC wall power? Or just can do it throughout the USB-C included?

Q: 3. I have the Panasonic DMW-DCC12 and an Anker PowerCore 13000. Will this work with those two items to power my GH5? Can you tell me how long I could shoot video with the GH5 with that battery and the Case Relay?

A: I have two of these that I run on GH5 and GH5s's using the Anker 13,000mah pack. I have only tested it with the Tether Tools adapter, but it sounds like it should work with the Panasonic adapter equally from what I read. I actually ran full tests just this week. On the GH5s at 4K/30p/100mbps with the display screen open/on, I shut it off when the Case Relay was red but still running at 7 hours and 50 minutes! I also tried on the GH5 and was getting around 7 hours or so. I ran the GH5 with the Panasonic XLR adapter and two SM81 mic's on phantom power and it ran for 6 1/2 hours continuous.

Q: 4. Does this Case Relay include the CRUPS110 adapters including the Nikon 4 pin adapter?

Q: 6. Can I connect this directly to the DC port on the Atomos Ninja Assassin?

A: The Atomos Ninja Assassin supports NP-F series batteries. So if you use this in combination with the Relay Coupler #CRCNPF. I don't see this coupler in B&H's stock but you could ask them to carry it.

Q: 7. I bought this product and used it 5 or 6 times on an A7s and connected it to a Vlock battery with a 2.1 Amp USB port. When using the A7s the battery inside the case relay runs down and eventually the camera shuts off. In other words, it doesn't work for me. But if I turn the camera off the Vlock charges the Case Relay battery. It would appear the camera uses power quicker than the Vlock battery can charge the Case Relay battery.My question is am I doing it wrong? What can I do to make it work like it is advertised?

A: This is a quirk - you have to unplug the power pack from the relay and replug. The relay will indicate it is charging. If this fails, unplug from the dummy and replug. It will catch and function properly from then on. Not intuitive.

Q: 8. Will it work on my Canon 5DSR? And how long is the wire/cable if I will connect from camera to power outlet?
