Question 1

The description and pics aren't clear. Is this also a wall charger, or only a car charged adaptor?

Accepted Answer

It is a dual charger.  It can use 110 ac or a usb connection.  It is not a car charger unless you have a 12 volt dc adapter with a usb plug in or you can charge it through your usb connection in your computer.

Question 2

My original battery says 6.8v.  this one reports 7.2v.  are they still interchangeable?

Accepted Answer

My original battery is 7.2 volts so this replacement works fine. My camera is a Sony HDR-CX380. Do you have a different model that would account for the difference in voltage? To the comments that the battery is difficult to put into this charger; The charger comes apart into two pieces. I have found that if I separate these pieces, it is easier to slide the battery in. I have had no problems with the charger or the two batteries that I received with it.

Question 3

Does this work with 230v AC input or it will work only with 110v?

Accepted Answer

I believe it works only with 110v.  It is one piece with a fold-down plug.

Question 4
