Hi all,

I was recently given a USB power bank (2000 mAh) as a birthday present but I’ve been unable to get my 5th Generation iPod Touch to charge using it.

Is this because the two are incompatible in some way?

If I buy another power bank at some point is there anything specific to look for to ensure compatibility with the iPod?

Many thanks in advance.

Kind regards.

What is the output of the power bank? how does this compare with the output of charger the iPod came with?

Many thanks for your reply. I've checked both my Apple charger and the power bank, and the specifications for each are as follows:-

Apple Mains to USB Charge A1399 - Output = 5V 1A.
Kodak Charger KPB-S 2000mAh - Output 5V 1A.

I've had problems with third-party accessories not working with Apple products in the past due to not being Apple approved - MFI certification? - could this be the case with this power bank?

Thanks again.

Does the Kodak charger correctly charge other USB powered devices?

Are you using the same cable with it when charging the iPod touch as when you charge the iPod touch from other USB sources? I'm assuming of course that the iPod touch does charge fine from other sources.

There used to be a time (several years ago) when some USB chargers (both mains powered and portable) did not provide the necessary signalling on the data-lines to indicate that they were a USB charger, resulting in Apple devices refusing to charge from them, but I doubt there are many of them around today so that shouldn't be the problem.

Provided you are using an official Apple cable or adapter (with either the Apple Dock or Lightning plug, dependent on the device), it shouldn't matter where the USB power comes from, or the amperage of it. A 500mA source such as from a standard USB 2.0 computer socket is sufficient to charge an iPod touch fine (the iPod touch doesn't even come with a charger, just a cable to connect to a computer).
