Yes. The Practical Meter will work with the iPhone 5! In some of the pictures in the campaign, you can see my personal iPhone 5 being used. The Practical Meter can be used in-line with your native cable or you can use the 30-pin to Lightning adapter with our optimized charging tips, to rapidly charge iPhone 5.
We are unable to offer the Lightning adapter itself or a Lightning cable as part of our optimized charging kit at this time. We are investigating this issue and will keep you posted.
