Voltage charger

Is it a USB charger? In other words, does it have the USB style outlet?

• If it states that its output voltage is 5.4 volts, I would say it's not suitable for your iPod. (USB supply is 5 volts, not 5.4 volts.)
• If it does have the USB style outlet, then it should be okay, although 5.4 volts is very slightly higher than the USB voltage.
• If it is not a USB style device, the best advice is to avoid using it for your iPod becasue it could damage the iPod (if the polarity is reverse to the iPod's requirements.)
• If you are unsure, then don't use it. Better that than ruin your expensive and delicate iPod.

I think the word "fake" is probably a bit strong. In fact, unless is claims to be made by Apple (i.e. their name is on the charger), then I think you will find it's simply a universal USB power supply, and not a fake. It can therefore act as an iPod charger - if it can supply at least 500mA. That should be written on it or in the instructions.

As such, yes I believe it's fine to use with your iPod. Note that this is not a guarantee.

I notice that you now say the output voltage is 5.31volts. Are you measuring this with a voltmeter? When you previously mentioned 5.4volts, I assumed that this was stated on the charger, but if you are measuring it and got that voltage, then in my opinion I think that's fine.

So the difference between the two chargers is:

Apple branded one: $19

Unbranded one: $3

It's possible to buy an MP3 player for far less than the cost of an iPod. It will play music etc. But that doesn't make it a "fake".
