this coupler / DC power cord is (7.6v). but the battieries are rated 7.2v. would this voltage damage my camera over time or anyway?

Let me start by saying that so far, I've only connected this power supply long enough to verify it wasn't DOA. However, I'm an electronic engineering technician by trade, and have done some DC power supply design and prototyping. Generally, whatever voltage the battery or other DC power source provides is further regulated and conditioned before being passed along to more sensitive, delicate circuitry. So putting out 0.4V more, or having a bit of 60Hz ripple is very unlikely to have any effect at all on the camera. Solid state electronics usually operate on 5.v, 3.3V, 2.V, or 1.8V, each with a tolerance of 5% or more. Typical lithium cells seem to be nominally around 3.6V (or 7.2V for two in series). The charging of all lithium cells is carefully managed by elaborate controller chips, so I wouldn't worry.

It hasn't in my case. Most electronics logic and components sensitive to a .4 Volt difference run at 1.8V, 3.3V or 5V, as well as the fact that batteries voltage can drop up to a volt or more from full to empty, so there is circuitry to drop a range of voltages down to logic levels and that circuitry should handle the extra .4 volts. That would be the close to limit in my case, though, at which point I'd confirm against Sony branded equipment (the sony adapter is 7.6V as well).

Nominal voltage for most typical Li-Ion/Li-Poly batteries is 3.7 volts per cell (some older chemistries are only 3.6). This corresponds to approximately 50% charge.So a 2S battery such as the NP-FW50 is nominally 7.2-7.4 voltsHowever, the peak voltage of a Li-Ion/Li-Poly cell is well above 3.7v/cell - a 3.7v cell will typically be 4.2v when fully charged, so a 2S battery such as the NP-FW50 will be 8.4 volts when fully charged (or 8.2v if Sony is still using a very old chemistry). 7.6v is well below this. :)

Krys I've used this setup on my Sony a6000 for almost a year now everyday with no issues at all. Good luck

There are apparently people using this attached to a 9v battery brick and using it without problem. Meanwhile, someone put a volt meter on Sony's own AC adapter and it seemed to deliver 8.4v (despite saying 7.6 on the label). I'm under the impression these cameras can handle a range of acceptable voltage.

i dont about the trigger voltage on novatrons but it will fry your camera if its more then 6volts. Most old studio stobes put out alot 100-400volts. but if your using a radio slave like a pocket wizard you should be fine. also i've noticed it only wants to play nice if there's also a flash on the hot shoe. i use mine on a t1i with a on camera flash via a bracket and seems to work ok that way

I don't know about the specifications of your camera but the Kodak USB power supply has a max output of 5 volts at 1.0 amps. As long as your camera charging input does not exceed this rating you are okay!

What exactly is your question? Check your power supply. Make sure you have 12v. If you can confirm that then meter the ends of the longer 20 ft cable to find 12v as well. If confirmed there then may be an issue in the camera

The camera comes with a small adapter that is powered off of the 115 VAC system. This AC-powered adapter supplies 5 Vdc at 1.5 Amps, so it seems likely that any source of 5 Vdc at 1.5 A could power the camera.

The large LEDs do use twice the current as most cameras. It does sound like a power supply issue / voltage problem at the camera. any way to see if you are getting 12volts at the camera in black & white mode? Agree with Sam on bigger powersupply & cable. I soldered my connections.

I am not sure. I used it for a 12V CCTv camera system. It works well. I am not sure if it is rated for 19V. Also, you will need more info about the polarity of your laptop.

Have a look at the back of your power brick (you may need magnifier, I do), it will have an output value saying ___ VDC. If that is 12 or 19 then you should be good to go.

Mine is connected to my camera and 12 volt battery and all of the power and ac/dc cables are plugged in but it won't work.

I can't say that the plug would not work up to 36 volts. It really depends on how much current you want to draw through the extension. The difference between your linked cable and this one, if any, is wire size. The wire thickness in this pretty small, I could not tell you exactly. It seems to do fine with a camera amount of current draw, but I'm not sure how much more it could take than that.

I recently put 6 of these around my house. The power adaptor that came with this camera is listed at 8Vdc 500mA... however, I connected a couple of my cameras up to my variable voltage bench supply, and I can confirm that this camera will run up to [at least] 12.5Vdc! I didn't want to spend the $15 to continue increasing the voltage to see where the camera lets the smoke out at... but I would assume that they are good for up to 15Vdc... However, as you increase the voltage, parts of the camera will get warmer (due to the LDO regulator within)...

I use it on cameras that require 12V and it works just fine. No problems whatsoever! Definitely worth the purchase if you install multiple cameras.

DC voltage drops rapidly with length, so too long a dc line will have a voltage drop that will affect the performance of the camera. In my case I extended an AC line into the garage to setup my camera. Perhaps in your case an AC extension cord may work ?

I believe you need to look at the plug you would be plugging into this. If the plug says it can handle dual voltage, then you are fine. Most cell phone chargers can be used with dual voltage. Chances are your camera charger is the same. It should say on the plug for your camera though.

I am told that voltage and current must match. Check camera info and go from there.
