No. There is no external power source input to this camera. You have to keep the batteries charged. Odd they left that out.

There actually is no battery built into this. It's a hot shoe adapter but it won't power all things you put onto it, if any. I bought it so I could mount an external microphone on my dslr and it works great for that. Hope that helps clear some stuff up for you

The cord that comes with the external power bank has a USB end and the other end attaches to your device. The external power bank is charged by plugging the USB end into a USB outlet and the other end into the external power bank. Once charged, you have power on the go. No batteries needed.

Draws external power. One of these models has a micro usb port to power it. I usually just plug it into the cisco device im using it on. It also comes with a pair of wire leads that you could use to fabricate a battery pack.Another option would be to use a usb powered cell phone charger battery pack.I love mine.

It doesn't use batteries. It gets its power from the USB connection on the laptop or computer.

I suggest going to their website to get the answer to this question. You can probably find the manual online. I have no problem using it as a battery powered device.

Only if your devise is battery powered like the radio on my boat. It's powered thru the USB port.

This is not powered by battery. It is powered by plugging it into an electrical outlet.

unless you have one of those USB Back up battery for when you don't have electricity. You'd still need to plug it into a power source. Doesn't have a stand alone battery.

This unit is powered by the USB connector on your computer. No external power supply.

This devise has a built-in long-life battery. It is designed to be charged externally on a regular basis. They come with a car-adapter plug (cigarette lighter) for charging, and can be used while charging. You can also use a home adapter (does not come with devise) to plug the cigarette plug into a house wall outlet. In short -- the batteries were never intended to be 'replaced', simply recharged.

It will function without external power. Using external means there is less drain on your (Laptop) power.

No. This is totally portable. No external power needed. It will not charge devices it is just a hub which is exactly what I wanted. It works terrific.

No external power source needed. Just simply plug in the 3.0 USB to the PC and you are set. :)
