The picture shows an input for external power. does it?

It runs on AA batteries but you can buy a adapter for a Sony battery which is a good idea if you use Sony batteries for your camera

Sorry but mine is the same answer as the other fellow. Mine does not. they updated the lights, probably because of complainants. I believe that electric plug is just for charging the bigger camera batteries that you can put on them. I would try to contact them for the answer. I have the old model and either you have to turn them off between subjects or have plenty of batteries on hand. Would be nice to have electric, I agree. Good Luck.John.

No mine does not. It appears that the model has been updated. The lights I have are battery powered and drain batteries with 1 usage. I'm planning to return the product.

Good question, dont remember if it actually does. I pretty much use it via USB power.

no it does not have a external power supply in the box. Although it does have an input jack for a 5 vdc power supply to be added. These are very common and easy to pick up at any electronics store

Nope. The cable serves as a way to draw additional power from diff USB ports, usually used for external hard drives.

no it does not, it is a Direct Current power source, and would not work properly with any standartd USB or in house items

I don't know. I would assume so, since it has it's own external power supply.

No. It gets its power supply from the raspberry itself. No need for external power

The switch does need external power. I removed the switch when it defaulted and blew out the HDMI input on my TV. I wouldn't suggest using it--period! !!!!!

Probably, since it plugs into the usb port of your computer and nothing else (no external power supply needed)

As built, do not see how that is possible. Tested it and doesn't work. There are external power supplies available.

I guess there is a external power input, but it does not come with an adapter. so pretty much batteries only.

No you don't need a external power source that's the whole point of this one over other ones that require it red wire is in parrelel with load yellow wire is in parrelel with the shunt along with the ground the shunt is in series to the the load and power source the current is sensed through the voltage drop across the shunt and the voltge is simply measured from the red wire to the black wire last picture has a very simple schematic

The device uses an external power supply. If you have needs other than 110V, you'll have to supply you own.

There is a power supply that comes with the device. I was worried about the same thing since it wasn't shown. But it did arrive in the packaging.

No it has three built in outputs (the button to switch one input to the other and then the two USB outs to the computers) on the front there is a DC input, but mine is not pulled into a power source and has been working fine for the last year.

No external power supply on this unit. Just a regular 2 prong plug straight from the unit.

No, it is powered by a cable which is included. It plugs into a standard outlet.
