Is 6v too much for an ipod 5th gen video? Answered

I have a 6v charger, just wondering if i could run that to a usb port and charge my ipod from that. will it fry it? planning on running it to a female usb plug then just plugging up ipod with usb cord.


Aelias36 is wrong about one thing: surplus current capability isn't a hazard. Current rating on a power supply -- unless it is specifically current-regulated rather than voltage-regulated, which is extremely uncommon outside a lab -- is the maximum current that the device can safely draw from that power supply. That number should be as large as OR LARGER THAN, what the device needs; it will only draw as much as it needs.

Voltage is a different matter. Yes, I'd be nervous about exceeding the specified voltage by a significant amount; I'm guessing that you would get away with it but I wouldn't bet my own iPod on it unless I had to. So I'd recommend that you put a 5V regulator circuit between the power supply and the output.

Getting back to current (needs rather than availability): As I understand it, for USB to put out its full power the device and the port actually have to exchange some signals agreeing that it will do so. If you just plug into a "dumb" power-only USB jack, the device is supposed to only draw about a quarter of that, and should charge correspondingly more slowly. If so, then again you need some logic in your charger rather than just wiring it directly.

There are lots of Instructables having to do with USB-based chargers. I'd suggest looking at them for more information.

... Y'know, the simplest solution might be to get a cheap ($10?) powered USB hub. That should have the logic to handle the faster charging negotiation, and I *think* it will do that even if it isn't connected to a PC. Or get a real USB charger; they're probably in the same price range by now, and might be available used for much less than that, given how many devices have now standardized on that connector.

Um, yeah, what he said.

(I really should have remembered that...)

I've tried it once on a Creative MP3-Player. It didn't work, so I would advise you not to do it if you don't want to ruin your Ipod.
As orksecurity said, just go buy a USB-charger, those few bucks you'd save are not worth the risk.

I've been told that a good rule of thumb is that electronics can handle about 0.7V more than their rated, I wouldnt trust 6V, and like astroboy said, you have to make a special resistor network for the ipod to know it should charge, that is to prevent people from using any old charger and messing up their devices. Also if you use an underrated charger, the ipod wont be the only thing at risk.


USB power is usually 5v at 500ma. Because the voltage can actually fluctuate higher, (I think 5.2v is the maximum allowed by standards,) it *may* work with this higher voltage.

Current is a whole different issue, though. If it's too high, which it most likely is, it will fry the circuit in a matter of seconds. The adapter will say its current rating, and if its more than 500ma, it could prove dangerous.

except you might have to guild a custom resistor-array type thing to get the ipod to recognize its plugged into a charger.
