NO POWER TO MY jvc DVX707

The battery is bad.

As long as you have a USB port and there is 4 AA or AAA batteries then you should be able to. USB is 5 volts DC and 4 batteries are 1.2 volts each and 4 equal 4.8 volts DC.

Yes it is the dc socket that you will use to charge your battery . It charges right on the camcorder itself with your ac adaptor . make sure the camcorder is in off postion for it to charge.

Can you plug the camcorder into the wall via the provided dc cable and your ac adaptor? If so your battery terminal cound have gotten bent, or a fuse link could have opened up inside. check above test first.

you can search ebay:

I bought a replacement data battery BN-VF-808U from Digicowfish through Amazon.com. (?made by PomerPower).
It fits nciely to my JVC Everio GZ-MG330 which uses a BN-VF808U data battery. However, JVC gives a screen message:Communicating Error.
Now I have solved my Communication Error by using a jumper cable provided with the replacement battery BN-VF808U to connect the attached replacement battery to the camcorder. There is a DC input socket on the camcorder. There is also a DC input socket on the replacement battery for direct connection.

The only suggestion is that it's a faulty battery. You said the camcorder is new, take the battery back, it's under waranty, and get a new one.

Try using the orijinal JVC battery, sometimes compatible batteries cause this kind of problems.

Order the original adapter from JVC. The adapter supplies the correct current requirements to operate the battery charge circuit. JVC's web site is JVC.COM. The correct charger will provide up to 1.5 amperes of current for the charge circuit at approx. 11 volts DC. Good Luck Joe Weibel Custom Electronics (customelectronics.org)

Just found a workaround for the "cheap battery" problem. The problem is that there is some circuitry in the more expensive JVC batteries that the generics don't have. When this isn't detected by the camcorder, it won't function. It's a neat trick to make you buy the proprietary battery. Also suspecting that with the JVC battery, if the circuitry gets fried for some reason, the battery will no longer work. Well, the generic battery I have has a plug in the back of it so you can charge it with the JVC factory supplied charger. There was also a jumper cord supplied with the camcorder. Plug this in the back of your cheap battery, plug the other end into your DC port on your camera, and voila! You're in business. Downsides are that you have a short cord between the battery and camcorder and the battery indicator won't work so you'll need a spare.
