Cons - No battery level indicator / Doesn't charge phone or boost the battery at all - only slows iPhone discharge rate / Uncomfortable to use.

The other units could recharge the iPod, whereas TuneJuice merely slows the rate at which the iPod's battery runs down so you must keep it connected continually.
