Q: I have an older, third generation iPod that came with a power adapter that connects to the iPod’s Firewire cable. I wonder: can that adapter can be used to safely charge my new fifth generation iPod as well?
A: It most certainly can – if, of course, you also have a Firewire-to-Dock Connector cable. Any existing iPod or iPod nano can be charged via Firewire. For other readers, however, the same is not true in the opposite direction: first- to third-generation full size iPods cannot be charged via USB. Below is a full table of each iPod’s charge and sync capabilities over Firewire and USB 2.0.
|1st Gen||–||Charge & Sync|
|2nd Gen||–||Charge & Sync|
|3rd Gen||Sync only||Charge & Sync|
|4th Gen||Charge & Sync||Charge & Sync|
|Photo||Charge & Sync||Charge & Sync|
|5th Gen||Charge & Sync||Charge only|
|1G/2G mini||Charge & Sync||Charge & Sync|
|1G/2G nano||Charge & Sync||Charge only|
|1G/2G shuffle||Charge & Sync||–|
