The Griffin TuneJuice has similar
problems. I want to be able to leave the battery
attached to my iPhone without having it hang off
the iPhone.
While I have really
enjoyed my two Mophie JuicePacks (and my
husband will continue to use my older one), I want
to take some time to compare the prices, structure
and battery capacity of several other possible
choices.
When you are comparing
devices that accept standard batteries, it is pretty
easy to compare AAA and AA batteries. However, when
the device is the battery, it would be difficult to
compare battery volume. Fortunately, the industry has
taken care of the problem by adopting a common
measurement, the battery capacity which is expressed
in mAh. The higher the mAh, the more power the
battery holds. While we often see cell phone battery
capacity expressed as talk time and standby time,
those numbers can be misleading.
Since I am looking for an external battery that will
also act as a case for my iPhone, I am looking at
three different options:
At the end of this
exercise, I have ruled out the inCase PowerSlider. I
have a white iPhone and I really don’t want
another black case. The difference in mAh is not
enough to give it a clear advantage over the mophie
juice pack air and I like the idea that I could buy a
replacement for the top case if I lost it.
However, the FastMac iV has several good features. It
has a clear advantage in battery power. The
integrated light is interesting and the extra USB
port might be nice. I guess I won’t be making a
final decision today and I might consider eventually
buying both units.

Good luck in making decisions for your iPhone
accessories!
