Average Reviews:
(More customer reviews)I bought and compared TuneJuice against two other iPod power sources that use disposable batteries. TuneJuice was the least effective and least convenient, but it did help somewhat.
TuneJuice requries four batteries, versus one or two for the Turbo Charge units I tested. 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. The iPod doesn't actually recognize TuneJuice as a power source.
When TuneJuice is connected, the iPod either cannot display its battery level or it gives inaccurate readings. Consequently the battery level may suddenly drop from "full" to "empty" without any warning.
TuneJuice can't power the iPod's if its internal battery is so low that it demands an external power supply. The iPod doesn't recognize it, can't recharge, and won't work.
TuneJuice doesn't take advantage of the full capacity of its AAA batteries, and stops working when the batteries are about half-empty. (You could use them in some other appliance that isn't so finicky.)
Despite its limitations, TuneJuice will modestly extend the life of a well-charged iPod. It's better than nothing, but certainly inferior to some other choices.
