2018 Update: The Mophie Juice Pack is still an awesome addition to your smartphone. No need to run out of battery while on the go.

Last year the #1 item on my iPhone Accessories Gift Guide was the Mophie Juice Pack for iPhone 3G and 3Gs. When in Vegas for CES I stopped by the Mophie booth to talk about how much I loved my older juice pack. But I had since upgraded to an iPhone 4, so I could no longer use it. The rep happily gave me a new Mophie Juice Pack Air Plus for the iPhone 4. This is a permanent fixture on my phone. Even though the battery on the iPhone 4 is greatly improved over past models, it is still a must to have a backup if going out all day.

I like the design of this newer unit a lot better than the model that I had for my iPhone 3Gs. Not that it was bad, but this one is a lot sleeker.  It also has better grip. The older unit was hard plastic and kind of shiny. This one has a soft matte finish that hardly shows wear.

The Juice Pack Plus for iPhone 4 is available in black, yellow, magenta, and cyan.

Although I love switching up cases sometimes to change the look of my phone, I make sure that I have my Mophie on my phone when going out for long periods of time. If you have an iPhone 3Gs, you are probably very familiar with having to charge your phone halfway through the day. When at conferences, etc. it’s common to see people charging phones, sitting near wall outlets, or asking friends if they can borrow their iPhone charger for a bit. With a Mophie, you would no longer have to worry about any of that.

Mophie Juice Pack Pros

  • Offers double the battery life for your iPhone4
  • Portable charging whenever you need it. No cords to carry around.
  • A very sturdy case that also protects your phone.

Mophie Juice Pack Cons

  • Makes the phone quite a bit thicker and bulkier
  • Makes the iPhone heavier

(neither of these is important in the scope of things)
