Thanks Brandon! I believe the official Panasonic solution includes a USB cable, although I think it takes a standard 5v signal and then uses a step-up converter to bring it to the voltage the camera needs. Fortunately, with the G80/G85, it's not that high, so standard USB at 5v should be able to handle the current requirement, but because there are multiple voltage conversions, you theoretically lose power from the battery (no conversion is 100% efficient). With the USB PD option, there's only the single conversion within the battery. I might have to get the 5v to 9v USB cable to see exactly how much of a difference it makes powering from a 5v socket vs directly from 9v on the Type-C socket using power delivery.

You and me both!

Haha, thanks, Richard. :)

Ahh, that would be cool. Those long exposures can chew through batteries quick on a DSLR!

Yeah, it feels like a great solution for overnight timelapses. Now that Scotland's starting to open up again, I'm hoping to test the theory soon, lol.

Well, some cameras are implementing USB-PD natively now, which is nice to see!

I've got an LP-E6 dummy battery here for when I use the Blackmagic Pocket 4K. I wish I had a Pocket at the moment so I could test it and see how much current it actually pulls because it's struggled in the past with some of the power solutions I've tried.

I haven't seen any dummy batteries with build in USB-C sockets, but there are a few batteries that charge over USB-C now instead of requiring a dedicated charger. SmallRig and Nitecore are the two brands that immediately spring to mind, although they don't make them for all camera brands/models.

De nada, me alegro de que haya ayudado. ¡Gracias por ver! :)

Glad you liked it!

Yup, no info on either of those things yet, but it's definitely promising, especially for the cameras that don't yet support USB PD power directly, or for things like long-term timelapse.

I'm not sure, really. The crowdfunding campaign wasn't successful, so I don't know if the products will ever go on sale. There are a few alternatives out there now, but I haven't tried any I can specifically recommend. but what you need, basically is a 9v USB-PD cable. Beyond that, as I said, I'm really not sure. Sorry I couldn't be more help. :)

Basically, any power bank that has a Type-C socket that supports USB Power Delivery at 9V and at least 2A would work. Then you just need the USB PD cable shown in this video, an EN-EL15 dummy battery (not the official Nikon one, they have a proprietary square socket - I posted a link to one in the description but you just want to make sure it has a 5.5x2.1mm barrel jack on the end of it). That's how I do it on the regular D800.

Omars and Novoo are the same company. Novoo is one of their brands they release some products under. The smaller ones are still on Amazon UK (amzn.to/32awyxD) but I don't see them on Amazon USA anymore.

Hi there! I'm not familiar with Lanparte's V Mount plate or the power requirements of the S1H. These cables use USB-PD to deliver 9v straight to the camera (the camera then just thinks there's a battery inserted internally). I'd suggest contacting Lanparte directly and see what they say.

Explaining that is kind of what the whole video's about, haha. USB PD (Power Delivery) power banks support this function. That's how I'm able to show it in the video. I suggest you check out the GreatScott video I liked in the description for a full explanation. :)

@@JohnAldred I understand your method is to use the USB-C conversion principle. You can connect any power bank directly to USB-C to get the highest original voltage of the power bank, such as 9V, instead of the 5V of USB. I see other methods are to use the USB/dc, 5v of the power bank, connect to the DC coupler, and convert 5V to 9V, so there are two more conversions, so your method is the simplest, best, and most economical . thank you!

Yeah, the inefficiency of losing power to multiple conversions the big problem with converting a 5v USB output to 9v is that it requires more current at the lower voltage. If you need 2 Amps at 9v (18W) to power a device, that means you need 3.6 Amps at 5v to get the same overall power. Most power banks don't put out anywhere near 3.6A (most are capped around 2 Amps) at 5v - and if they tried, they'd probably get VERY warm (potentially warm enough to start a fire). I've got a couple of those cables that step up a Type-A socket to 9v and 12v, but they're current limited to about 500mA at 9v and 12v for this reason.

Hey Eric! I'm doing a test with my Panasonic G80 now in timelapse mode. I've set it to do a thousand shots (one every 10 seconds), so I'll come back to it in a couple of hours, see how it did and let you know! For my own reference (so I can see how much it's dropped when I come back, haha), the power bank I'm using is an Omars 45W 20,000mAh and it's starting off at 66% charge. :)

Ok, 1,096 images shot, ten second intervals (so about 3 hours), electronic shutter (just so the noise didn't get annoying, lol) LCD on the whole time, no problem at all. The power bank has dropped down to a 60% charge (from 66% at the start). Camera's now gone into standby, tapping the shutter or menu button wakes it back up.

@@JohnAldred Sweet! that is good news. I was actually just contact by Arseniy, Good information to know. I appreciate you doing the test for me. I will be backing his project. I assume that if it works on the battery pack it will work with a USB-C power supply as well, like an iPad pro power adapter or a MacBook power adapter.

I would expect so, yeah. Check out the timelapse rig video I just posted. I'm planning to switch that to exactly the setup you mentioned for powering the camera. Right now I have a whole separate AC adapter for the camera, but I'll be swapping over to a USB-PD charger and powering the Pi and the camera both from that.

The cable came through a crowdfunding campaign that wasn't successful, so this specific brand/product is no longer available. There are a number of similar cables out there that do the same job, though. You'll probably have to do a little hunting on eBay and AliExpress for them.

No, it's not just a regular straight cable. There's electronics inside the plug to negotiate the USB Power Delivery connection. So, you'll need a specific USB-PD cable for this. Making your own DIY option isn't completely impossible, but it's not really practical because of the size of the electronics and the time it would take (and the risk of potentially killing your gear).

@@JohnAldred Please can you sent me a link to order this cable..thanks

The one in this video isn't available. The crowdfunding didn't hit it's coal, but if you search for a 9v usb pd cable on AliExpress or eBay, you should get some results for similar.

If it's one that supports USB-PD and you have the right USB-PD cable to give a 9v output, I would expect it to work, but I've heard that Sony cameras can be funny with external power supplies sometimes. I wouldn't have thought you'd need it on the A6400, though. Doesn't it support USB power through the micro USB socket?

Hey I believe so. I linked my dummy battery and powerbank below. When you have time, do you mind having a look to see if this would work and give me a few hpurs of shooting time? Dummy Battery : www.amazon.co.uk/dp/B07NWBBR2T/ref=cm_sw_r_apan_glt_fabc_6KBY9FW8GEQG5MX7KZ9X?_encoding=UTF8&psc=1 Power Bank: www.amazon.co.uk/dp/B07S829LBX/ref=cm_sw_r_apan_glt_fabc_N1MHGT7P1D1RZNK11Z1K?_encoding=UTF8&psc=1

That power bank doesn't offer USB-PD. The Type-C socket on it, it says, is for charging only, so it wouldn't work with these types of cables, and it only outputs 5v at up to maybe 2 Amps on the Type-A sockets. The cable's also different. It's not a USB-PD cable like the ones in the video. That only works on the 5v Type-A socket and then uses what's called a buck converter to step up the voltage. The short version is that if your camera needs 1 Amp at 9v, then it's actually pulling 1.8 Amps at 5v. If it needs 2 Amps at 9v, it's pulling 3.6 Amps at 5v (which is way above the spec of most Type-A USB sockets - and certainly more than that power bank you linked can handle). I don't know how much current the A6400 draws when it's using different functions, but I tend to avoid the step-up cables, just because they can often draw more current than the batteries can handle due to the fact that they're pulling 5v from the power bank and not 9v. I tried them a couple of times with my Nikons and they failed miserably. They just couldn't supply enough power and got REALLY hot because they're not designed for that high current. The combo you linked *might* work to power the A6400 (but it also might not, I couldn't really say without trying it), but even if it does, I couldn't say for sure how long without knowing how much current it's drawing at the voltage it's expecting (and there's also a power loss during the conversion process from 5v to 9v or whatever the cable outputs to the camera).

I've no idea. It's going to depend entirely on what electronics are inside the dummy battery or cable (if any). You're going to have to ask the place you bought it from. :)

@@JohnAldred Yeah i got a anker powebank just to be sure! They have 5V 3A

If it's just a regular 5-9v step-up converter and not USB-PD, then once it converts it, that 3A @5v is only going to be 1.66A @ 9v which may not be enough depending on the camera you're using. I've seen some cameras (particularly DSLRs) pulling over 2 Amps at 9v, especially when shooting continuous stills.

@@JohnAldred its powers my Canon eos m!

@@mp3remix171 Which converter are you using, and where did you buy it? I have seen 5v to 8.4v ones, but their output is limited to 1 amp.

USB-PD is unlikely to be able to work that way without a lot of extra electronics to deal with load handling and to prevent one power bank from charging the other. I haven't tried it with the Ninja V because I don't have one. Doesn't the Ninja V have a DC output? With my Feelworld monitors, I can throw an NP-F on the back and take a DC output to power the camera from that.

@@JohnAldred I don't know if Ninja V have a DC output... but C5 need 15 W of power and NP-F... well... I don't know if NP-F can handle that power... 37 W is something... about preventing one power bank from charging the other... indeed ... a lot of electronics needed .... I must search another way. BR

Sounds like you might be looking at v-mount batteries, really.

@@JohnAldred yep... v-mount...ing

No, because the 7.2 or 7.4v rating is a nominal voltage. Fully charged, those batteries will be closer to around 8.4v and almost all cameras are rated just fine to 9v. My Nikon D800 actually says it'll take 7-12v, the rest of my Nikons say 7.4-9v. And I had a Panasonic G80 powered from this and a USB-PD charger for a solid six months 24/7 while live streaming at the end of 2020 and beginning of 2021.

On my Nikon DSLRs and the Panasonic GH5, there's a little rubber flap on the body by the battery compartment so the cable can stick out the side when the door's closed. On the Panasonic G80/G85 and GX80/GX85, that little rubber flap is on the battery door itself and you just open it up and poke the cable through the hole.

@John Aldred My Olympus EM1 is weather sealed so I will have to rremove the door on the extra and grip

The GH5 and all my Nikons are weather-sealed, but, I don't really use grips with my Panasonics. I'm only using those for video. With the Nikons... if I'm using a grip, I'm handholding and shooting stills. So I'm not really using a dummy battery with an external power source. I'll just put two batteries in the grip in those instances. If I'm shooting timelapse with the Nikons where I do need external power, I just don't use a grip.

@@JohnAldred Duh I am an idiot, the Olly has and trap door for the power cable that Olympus never wanted to support, hence never sold the cable

Haha, thanks, Udi. Yeah, the prototype cable with the socket on it that lets me use any Type-C to Type-C cable... That's SUPER handy. I think this would be the ideal connector to put onto a dummy battery so we could use whatever length of cable we want.

It wasn't a useless video at the time it was posted. And It's still not a useless video as there are a number of USB-PD cables out there now that can perform this same function if you search eBay, AliExpress or Amazon. :)
