Induction charging and universal chargers

Aware this may not be the right section, but couldn't find a better place for it.

If anyone knows anything about batteries please answer. I recently got a Powermat induction charger. The main use for it is to charge electronics via induction to separately sold battery attachments and that I know is all good. But there is something else included with the package that induction charges to charger box (its called a powercube) and on the other end of the box is a standard mini usb which can be outfitted with the many different attachments (Sony, Micro USB, DS lite, etc..)

My question now, if I haven't complicated this too much: seeing as how all chargers have different charges, volts, hz, and what have you, designed specifically to the device, am I harming my batteries in all my devices since it is using one generic output, or is the device smart enough to regulate the power for each device.

Good question, which I can't answer. My total experience with this technology is my electric toothbrush.

That said, I would guess that the device operating voltage doesn't matter that much. I say that because all DC batteries have multiple cells in them. The higher the voltage the more cells. So, the cells need to be individually monitored to allow charging until they reach the target voltage.

Your best resource is the manufacturer of the device and the manual. Should explain things.

a device needs to be compatible with the charger (there is no magic involved!)

if the numbers don't match - it might still work but the battery life will be shorter, the hardware might overheat, and other issues may occur.

Oh yeah, they all work. Charging lights turn on the devices and everything (with the exception of my camcorder that if you powered it on while charging it would show a display, this one turned on but the screen was black)

So yeah basically, that's exactly what I'm concerned about, is destroying the life of the battery. The stats on the chargers make me skeptical as well as the fact that certain chargers have a large..... something attached to them (Lets take the Sony PSP charger for example, in the middle of the cord is a big honking brick that I have no idea what it does) The universal charger does obviously not have that same honking brick in it, so yea, I'm unsure.

Thanks for the replies.

If anyone else knows, please reply.

Most chargers are matched to the device by the manufacturer. Induction coupled charging is very inefficient. So using such a device would cost more and probably take longer.

That device has a USB output, the only voltage it's going to output is 5 volts DC. All devices that plug into a USB port for charging use 5 volts DC, nothing else.

You will not harm your devices but as Wizard-Fred pointed out, it will probably take longer to charge then using the charger that originally came with the device.

I wasn't really intending on using the USB on it ATM. While it is handy to have around, most of the things I have that are USB charged, I usually want to use a computer for it, so I dual task with it. Ex upload songs on my zune while charging it.

Good to know about the USB though, if you are positive about it.

I'm more concerned with the powercube (induction to mini usb with attachments) Doesn't really matter to me if it takes a little bit longer as now I don't need that pasta bowl of spaghetti known as cords around. I just don't want to kill my batteries. I have crap 360 and wireless phone batteries that last for less then a minute after a full charge, I've been through that, never want to be again.

Yes, I am 100% sure about the voltage. You aren't going to hurt your batteries.
