Unfortunately, the current design is intended for use with the first generation Apple iPhone ONLY. The dimensions of the 3G iPhone will not allow for cross compatibility. We will be releasing a version of the Juice Pack for the 3G iPhone soon.
Will my current Juice Pack work with the new iPhone 3G?
When I try charging my iPhone and Juice Pack at the same time the iPhone keeps “chirping”.
If this happens, simply detach the iPhone from the Juice Pack and charge them separately.
My Juice Pack isn’t charging.
If both the iPhone battery and the Juice Pack battery are dead or very low, they may not charge simultaneously if the iPhone is inserted in the Juice Pack, in this case, the iPhone may “chirp” intermittently. If this happens, simply detach the iPhone from the Juice Pack and charge them separately.
I’m trying to plug my iPhone/iPod cable into the Juice Pack and it's not working!
The charging connector on the Juice Pack is inverted. You will need to flip the charging cable over before inserting.
Can I sync my iPhone while the Juice Pack is still connected?
The “Pass through connector” on the bottom of the Juice Pack is for charging only, it is not intended to sync your iPhone.
What is the battery capacity rating in mAh?
The Juice Pack battery capacity rating is 1800mAh.
