iPhone 4 with firewire A1070 charger

The original iPhone was the only one that could be charged with a Firewire charger. No later models (including all iPads) can be; the Firewire pin in the dock connector is not connected to anything in the phone. If I were to guess, continuing to support Firewire charging would have required 2 separate charging circuits in the phone, and there just wasn't room, and little incentive, because all newer devices come with their own chargers.

The good news is that you can use an iPad charger to charge an iPhone. The reverse works also, but v e r y slowly.

They will not work.

Will this damage the battery in my iPhone or will it just not charge.

It won't damage anything. It will just not charge.

What is the reasoning behind it?

USB ports have become ubiquitous. FireWire, not so much.

So this charger will only work for the iPod Mini and the original iPod?

Yes.

Firewire???

iDevices for the past several years due not accept power on the formerly assigned firewire pin. Unless you have one of the legacy devices that could still charge, but not sync, like the original Nano, etc., you will not be able to charge anything with those chargers.

One end of the cable is firewire (plugs into the charger), the other end is the 30 pin connector which would plug into the iPhone 4.

So I am not sure what you mean?

What I mean is that you are describing a FireWire cable that will neither charge nor damage your iPhone 4.

The photo is of a FireWire cable and two power adapters that will neither charge nor damage your iPhone 4.
