How many minutes cranking equals iPod play time?
Each iPod model consumes power at different rates. Our primary recommendation for iPod is that you power it off a fully AC pre-charged LED-98/99. A fully charged LED-98/99 will give you about 10 hours play time on iPod and 1 hour play time on iPod Video. However, for iPod 5 minutes of cranking equals 5-10 minutes of play time. Please also note that with iPod, when charging off LED-98/99, you must charge it only for one hour, and then unplug it, or it will start to discharge.
